A Chinese brand Magene recently released a new electronic road bike groupset, featuring hydraulic disc brakes under their QED line of products. I saw it in the flesh at both the Shanghai bike show. and Eurobike this year, and my first impressions were very good.
It seemed like an incredibly polished groupset, and I was extremely excited to try it out. It is currently only being sold in China, but they do have plans to make it available in other markets. However, someone using the groupset in China faced a problem with the braking system recently, causing him to lose control and he ended up breaking his leg in a crash.
Petr and his interviewee Mel speculated that the cause could have been something to do with the oil reservoir within the shifter. Essentially if the reservoir is not big enough, then as the brake pads wear, the pistons will eventually bottom out, and you will loose braking.
This is a failure mode I haven't even considered, so in this episode I will briefly discuss the issue, and then run some other Chinese groupsets from L-TWOO, Sensah, and Wheeltop, through a test to see if they also face any issues.
Please note: I am not a professionally trained bike mechanic. There can be risks associated with using products that are unbranded, untested, or come from sources where the provenance is unknown. Please talk to a qualified bike mechanic if you are in any doubt.
In essence, be careful, do your research, and cycle safe!!!
A New Chinese Groupset is Under Scrutiny - Magene QEDTrace Velo2025-08-28 | Firstly MASSIVE thankyou to Petr from Cyclists Hub for breaking this story on youtube, you can find his video here:

Sounds too good to be true right?
In this video I take a detailed look at their design, compare them directly with Shimano's 105, Ultegra and Dura-Ace pedals, and explain why I think they may have one major weakness.
The interesting part? I've already tested a very similar set of ultralight carbon composite pedals with titanium axles from a brand called Onirii. They were brilliant to ride, until they wore out in a way I wasn't expecting. So can these carbon composite road bike pedals from ROCKBROS avoid the same fate, or is history about to repeat itself?
These pedals were purchased with my own money. Nothing in this video was sponsored or provided for review, so everything you see is my honest opinion after riding and comparing them.
If you're looking for the lightest road bike upgrades on a budget, hopefully this helps!

In essence, be careful, do your research, and cycle safe!!!The Bike That Makes AliExpress Look Pointless...Trace Velo2026-07-01 | I’ve spent years building bikes with cheaper parts sourced from places like AliExpress, chasing the absolute best value for money. So when a complete carbon road bike arrived that was priced SO aggressively, I genuinely struggled to work out how they were doing it… I had to take a closer look.
The Sunpeed Invincible Sport comes with a full carbon frame, fork and seatpost, integrated carbon handlebars, Shimano 105 R7020 12-speed groupset, and hydraulic disc brakes. It also comes from a UK bike shop with a warranty, and you can even get it on the Cycle to Work scheme.
The price is a mere £1,399.99 ($1,850), which is frankly a bit bonkers. In this episode I’ll compare it against the competition (Ribble and Canyon), take it out on the road, completely strip it down, inspect the frame inside and out, and work out exactly where Sunpeed has spent the money, and where they've saved it.
Plus I'll even spec out a similar build from AliExpress to show you how crazy that value really is!
**Disclosure** Just FYI, this is not a paid video, and the bike is on loan from the distributor. If you do want to check it out, or any other bikes they do, use my discount code below. It’ll get you 5% off the price, and I get a little kick-back if you choose to buy from them 🙂

Email: tracevelouk@gmail.comWhen the Cheap Carbon Gamble Doesnt Pay Off...Trace Velo2026-06-18 | AliExpress can be an absolute gold mine for cheap bike parts. Over the years I've built lightweight fully carbon road and gravel bikes using components sourced entirely from China. But when you chase the absolute lowest prices, there are definitely some trade-offs…

In this episode we'll take a look at a carbon seat post from Toseek that failed on its very first use, leaving one of my viewers with a nasty leg injury. We'll explore what might have caused the failure, from quality control and layup defects to prepreg handling and the carbon fibre manufacturing process itself.
But, more importantly we'll talk about how to shop safely on AliExpress, how to approach ultra-cheap carbon components, and why not all Chinese bike parts should be treated in the same way. Because while some of the best value components I've ever used have come from AliExpress, not every bargain is worth the gamble, and you have to take the right approach.

In essence, be careful, do your research, and cycle safe!!!The Secret Chinese Factory Behind Premium BikesTrace Velo2026-06-05 | A few weeks ago I was given rare access inside FiberTek Composite in Xiamen, China - an OEM manufacturer producing carbon frames and other components for some VERY well-known bike brands.
In this episode I’ll document the entire manufacturing process, from rolls of frozen carbon prepreg and hand layup, through to EPS and latex molding, curing, quality control, testing, and final assembly.
However, one thing that REALLY surprised me was just how manual the entire process still is. Despite using advanced composite materials and modern manufacturing techniques, many of the most important stages still rely heavily on skilled technicians working almost entirely by hand. For example, modern carbon bike frames contain 200–300 individual carbon patches, each positioned according to a precise layup recipe.
We’ll also take a look at: • EPS vs latex molding • Carbon fork and handlebar production • Frame curing and internal pressurisation • OEM manufacturing for major bike brands • Carbon frame quality control • Fatigue and load testing • Why some carbon frames are manufactured in China but painted in Europe
A huge thank you to FiberTek for allowing me to film inside the factory, and to Joe from Panda Podium for helping make the visit possible.
#hoverair #CarbonBike #BikeFactory #CarbonFiberI Built the Ultimate Chinese All-Road BikeTrace Velo2026-05-22 | When I first showed a Chinese carbon all-road frameset a few weeks ago, a LOT of people were interested. So today, it’s finally time to build it up.
This bike is basically a full Chinese / AliExpress dream build. We’ve got a carbon all-road frameset from a Chinese direct to consumer brand called LightCarbon, deep section carbon wheels, integrated carbon cockpit, a budget power meter crankset, and the cheapest electronic groupset currently on the market, the L-TWOO ER7.
Honestly… I wasn’t expecting to like this bike as much as I do.
I had assumed the bike would be quite racey, stiff, and unforgiving, but despite the aero styling, it’s surprisingly comfortable, incredibly smooth on rough roads, and genuinely feels like a really well thought-out all-road bike. Plus at just 8.26kg with pedals, cages, computer mount and chunky 38c tyres, the final weight ended up being VERY impressive.
AliExpress parts here: https://linktr.ee/tracevelo
In this video i’ll cover: - The full end to end bike build - Ride impressions on road & gravel - L-TWOO ER9 electronic shifting performance - Weight & full cost breakdown - How the build compares to other bikes on the market - Whether an all-road bike actually makes sense
Bike weight: 8.26kg Total build cost: £2,121 ($2,850)

Today I checked out some of the latest smart trainers from Magene, alongside their growing range of cycle computers and power meters as they continue pushing further into the performance tech space. It’s honestly kind of wild how quickly some of these Chinese brands are evolving now.
There were also some very interesting new wheelsets on display from UpVine and No.6 Wheels, with both brands continuing to experiment with lightweight designs, new spoke technology, aggressive aero concepts, and some genuinely premium looking finishes.
On the braking side of things I spotted some absolutely enormous 6-piston disc brake calipers, alongside a few new shifters from a groupset brand called Polarway that looked VERY familiar to some of the Shimano offerings…
And one of the biggest surprises of the day was a new Triton road bike from Sunpeed that looked seriously impressive for the money. The value-focused end of the bike industry is getting extremely competitive right now, and some of the bikes appearing at this show would have seemed impossible at these prices just a few years ago.
As always, I tried my best to cover as much interesting tech as possible, but there is just an absurd amount of stuff at this show. Every hall seems to contain either something genuinely innovative, completely bizarre, or suspiciously similar to an existing product.

Massive thank you once again to the legendary Joe from China Cycling and the Panda Podium team for hosting me out here in Shanghai.
One of the most fascinating things I came across today was a new ultra-light disc rotor design from RideNow that immediately got my attention. They’re incredibly lightweight, don’t require proprietary brake pads, and seem to take a very different approach to the carbon-ceramic style rotor concept I’ve looked at previously. Whether they’re actually good in the real world though… that’s another question entirely.
I also got a look at a stunning 3D printed titanium bike that somehow manages to look both futuristic and slightly terrifying at the same time, alongside some genuinely beautiful chains from YBN and SUMC, two brands that continue to push drivetrain tech surprisingly hard.
Sensah or Senteyh, were also showing off an updated version of the 14-speed groupset I checked out last year, and there were loads of smaller tech-focused products around the halls too, including tyre pressure monitoring systems and some new carbon handlebars from CRW designed as direct replacements for Canyon’s proprietary cockpit setup.
And perhaps most importantly… I finally got to ride one of the latest ultra-budget Chinese groupsets that costs roughly $300... I was surprisingly good!
Honestly, every year this show feels bigger, stranger, and more ambitious. There’s an absurd amount of development happening in Chinese cycling tech right now, and even if some of it turns out to be nonsense, it’s never boring!
And of course Shane Miller @gplama, and the nero boys @NeroShowCycling are still all over the show, so check them out for even more coverage!!

Day two was absolutely packed with interesting tech, strange ideas, and some genuinely impressive bikes.
One of the coolest things I saw all day was a brand new modular groupset from SRide, designed in a way that could make servicing and repairing modern groupsets dramatically easier. It’s such a simple idea, but one that makes a surprising amount of sense once you see it.
I also checked out some incredibly cool folding commuter bikes over at Java, including a few designs that looked far more refined and practical than the folding bikes most people are probably imagining right now.
There was also a completely ridiculous money-no-object road bike build, alongside a quite confusing lineup of groupsets from L-TWOO, that left me with a few questions....
And of course, electronic shifting continues to be absolutely everywhere in China right now, with Wheeltop showing off their latest electronic groupsets and tech as more and more brands try to push into the performance road and gravel market.
Honestly, the sheer pace at which new cycling tech is appearing over here is kind of wild. Every time I walk around another corner at this show I seem to find something bizarre, clever, or unexpectedly impressive.
Again, massive thank you once again to the legendary Joe from China Cycling and the Panda Podium team for hosting me out here in Shanghai. If you could go and check them out, it would genuinely mean a lot.

This is day one of one of the biggest bike trade shows in the world, and as always there is an absolutely absurd amount of stuff to see. From a seriously lightweight gravel bike from Evolve, to FarSports showing off carbon thru axles with a very unusual thread attachment system, to one of the strangest bikes I’ve ever seen that literally has no bottom bracket....
There was also a brand new electronic groupset on display for less than $300 that could shake things up a bit, alongside some crazy looking new bikes, wild paint jobs, and bizarre tech experiments that make this show SO much fun to walk around.
I tried my best to cover as many interesting booths and products as possible, but honestly you could spend days in here and still miss so much stuff, it's honestly HUGE.
I’m once again being hosted by the legendary Joe from China Cycling and the Panda Podium team, and Shane Miller is also roaming around causing trouble, along with Jesse and Chris from the Nero show!

Email: tracevelouk@gmail.comDid This Chinese Groupset Just Copy Shimano?Trace Velo2026-05-01 | The Chinese groupset manufacturer L-TWOO have done something I really didn’t expect… They've ditched their Campagnolo-style thumb shifters, and gone full Shimano!
Today I'll be taking a look at their updated GRT gravel groupset. It’s a 1x12 mechanical groupset, and can support a frankly massive 11-50 cassette, but they’ve taken the design in a COMPLETELY different direction. You now get a swing-lever downshift and paddle upshift setup that looks very familiar, and pretty Shimano-esque. But the real question is, does it actually perform?
In this video I’ll install the groupset, take it out on the road, and see how it stacks up against Shimano, especially when it comes to shifting performance, braking feel, and overall value.
TLDR - The shifting is seriously impressive, but it’s not perfect….
What’s covered in this video: -Full install on an integrated cockpit gravel bike -First impressions of the new shifter design -Real-world road test -Shifting performance vs Shimano-style systems -Braking performance (and where it falls short) -Weight + cost breakdown
Bottom line, the shifting is the closest I’ve felt to Shimano from a Chinese groupset—but the braking still needs a bit of work. If they can sort that out, this could be a serious contender in the budget gravel space.

#hoverair #bikeupgrades #ltwoo #aliexpressThis One Ingredient Made Chain Waxing Worth ItTrace Velo2026-04-14 | Chain waxing felt like one of those activities reserved for the most obsessive cyclists, but after a year of experimenting with it myself, I think I found the ultimate additive…
SIROKO CLOTHING – 10% off (automatically applied via link below): srko.co/tracevelo
In this episode, I’ll take you through my full DIY chain waxing setup, the mistakes I made along the way, the various additives I tried, and the one ingredient that made the biggest difference: microcrystalline wax.
I cover how I clean and prep chains for waxing, my original paraffin, MoS₂ and PTFE blend, why I moved away from PTFE, and some of the real drawbacks of chain waxing that people don’t always mention. Things like flaking wax, cold weather issues, rust after wet rides, and the hassle of breaking in a freshly waxed chain.
I’ll also show you the updated formula I’m using now, why microcrystalline wax improved it so much, what my current process looks like, and whether doing it yourself actually makes sense compared with buying a ready-made system from someone like Silca.
If you’ve been curious about hot waxing your chain, or you’re already fully initiated and want to refine your own blend, hopefully you’ll find this episode useful!

Email: tracevelouk@gmail.comA Complete 2x Road Bike for £399 - What’s the catch?Trace Velo2026-04-04 | Checking out one of the cheapest drop bar road bikes in the UK!
On this channel, I usually build bikes piece by piece, often using cheaper components from AliExpress and other direct to consumer Chinese brands, but this time, I wanted to try a different angle. What happens when you just buy a complete box bike for £399?
SIROKO CLOTHING – 10% off (automatically applied via link below): srko.co/tracevelo
In this video, I take a closer look at one of the cheapest complete road bikes I’ve come across in the UK, and break down exactly what you’re getting for the money. From the aluminium frame and finishing kit, to the 2x drivetrain, Sensah groupset, and overall build quality, because at this price point, there are always compromises.
Why it’s interesting: A £399 road bike undercuts pretty much everything you’ll find from the big brands, especially on the UK high street. But unlike a lot of the budget stuff I cover, this isn’t a pile of parts from AliExpress…Iit’s a ready-to-ride bike from a physical shop in London.
Disclosure: I forgot to include it in the episode, but I did get this bike sent over for review, however I am not being paid by V-Ride or Sunpeed to make this content. If you end up buying a bike and use my discount code, this is how I make a small commission 🙂

In essence, be careful, do your research, and cycle safe!!!This Cheap Titanium Crankset Has a Weird Problem…Trace Velo2026-03-15 | I've tried a few cheap carbon cranksets from AliExpress over the years, and results have honestly been mixed. They can be nice and lightweight, but often they have some slight issues that need to be worked around.
In addition, one thing that has always made me slightly hesitant to fully recommend them is the fact most use aluminium axles. Not so much of a problem on DUB standard cranksets, but 24mm Shimano standard axles made of aluminium have had issues. While I’ve personally never had one fail, there have been reports of aluminium spindles shearing under high loads. NOT ideal!
So when I found a crankset from a brand called WUZEI, that uses a 24mm axle made of titanium alloy, I was really interested to give it a try. In theory it should solve that issue. Titanium is stronger and much more fatigue resistant than aluminium, while still keeping the weight extremely low. On paper it looked fantastic. Lightweight, well machined, and under £150. But once I installed it… there was a really strange issue, I’ve honestly never seen anything like it.
So in this video I take a closer look at this WUZEI titanium crankset from AliExpress, explain the design, and show the unusual problem I ran into when trying to get it shifting properly.

All for around $950 for the complete frameset.
That price almost sounds too good to be true, so I wanted to take a proper look at it.
SIROKO CLOTHING – 10% off (automatically applied via link below): srko.co/tracevelo
LightCarbon is a Chinese direct-to-consumer manufacturer that has been getting more attention recently for producing some high quality carbon frames at surprisingly low prices, and after seeing this frame in person at Eurobike last year, I was curious to see if it actually lives up to the hype.
In this video I’ll take a close look at the external paint finishing, internal carbon layup, manufacturing quality, and overall design, including a look inside the frame with an endoscope. I found a small imperfection in the layup, so we’ll talk about what it means structurally and how LightCarbon responded.
In this episode, I'll cover:
- Overview of the LightCarbon LCR018-D frameset - Paint quality and external finishing - Internal carbon layup inspection - Latex mould manufacturing process - Frame details: T47 BB, internal routing, in-frame storage - Weight and included components - The small imperfection I found inside the frame - How the manufacturer responded
LightCarbon primarily supplies frames to other bike brands, but they also sell frames directly to consumers. Details below:

Not just using cheap carbon frames and wheels, but full groupsets, integrated carbon cockpits, cranksets, cassettes, chains, all as cheap as possible. And honestly? Most of it works surprisingly well.
But there’s one component where I’ve repeatedly faced issues, the bottom bracket.
SIROKO CLOTHING – 10% off (automatically applied via link below): srko.co/tracevelo
In this video I break down why cheap bottom brackets, especially external BSA units, have consistently failed on me in real-world British weather. We’ll compare budget AliExpress options against OEM units from Shimano and SRAM, look at bearing quality, seal design, weatherproofing, and why some designs last dramatically longer than others.
I’ll also cover: - Why dust cap tolerances matter more than you think - The difference between generic cartridge bearings and custom lip-sealed designs - Why cheap BSA DUB bottom brackets keep seizing on me - Why T47 bottom brackets are such a good design - Whether facing and chasing your bottom bracket shell is really essential
If you ride in dry conditions only, your experience might be different. But if you’re riding through UK rain, grit, and winter roads, this might save you some frustration.

SIROKO CLOTHING – 10% off (automatically applied via link below): srko.co/tracevelo
These lightweight SLR Gen3 cassettes from a brand called ZTTO on AliExpress, are pretty incredible for the price. They are MUCH lighter than the equivalent cassettes from Shimano or SRAM, and you can find them for around £60-£70. They use some very intricate and frankly, quite good looking CNC work, and come in a bunch of colours and sizes.
The largest 3 gears are machined from a single block of 7075 aluminium, while the rest are made from a single block of steel, however it’s the aluminium gears that could be a problem.
A viewer sent me some pictures of his cassette where the top two aluminium sprockets had completely sheared or snapped off the back of the cassette. After taking a more detailed look at the design, it’s quite easy to see how this could have happened.
I have run these cassettes on my road bikes for over a year at this point, with no real issues, but it looks like it might be a good idea to proceed with caution when it comes to the 11-36 version of this cassette…

In essence, be careful, do your research, and cycle safe!!!This thing was terrible, for SO many reasons...Trace Velo2026-02-11 | This “carbon ceramic” disc rotor from AliExpress makes some very bold claims, but after testing genuine carbon-ceramic rotors on my road bike recently, I can tell you this is nothing like them…
SIROKO CLOTHING – 10% off (automatically applied via link below): srko.co/tracevelo
Despite being advertised as “carbon ceramic”, the braking surface on this rotor isn’t carbon fibre, carbon-carbon, or a silicon carbide composite. In fact, the brake track appears to be aluminium, not steel, treated with what looks to be a PEO (Plasma Electrolytic Oxidation) ceramic oxide coating.
In this episode I will: - Examine the construction - Break down the marketing claims - Explain why it may be a PEO coating - Put the rotor through real-world braking tests
The result? The braking performance was only part of the story.
If you’ve ever wondered how far AliExpress marketing can stretch technical language, this one’s interesting.
Setup: Tested on a hydraulic disc brake road bike using resin pads (as required by the manufacturer), across repeated stops and sustained braking to attempt a proper bedding in procedure, and properly evaluate heat behaviour, noise, modulation and consistency.

The shimano freewheel still span perfectly, impressive stuff!The BEST cassette on AliExpress!Trace Velo2026-02-03 | This is the SLR Gen3 cassette I bought from AliExpress. I've had two of them at this point, and the quality is very good for the price of just £60.
However, the selling point is the weight. This things weighs just 122g, which is bonkers.These had a BIG flaw… Have Elitewheels fixed it? - Velo Six IITrace Velo2026-02-02 | I tested the original Velo Six wheelset from Elitewheels a year or two ago, and honestly the lateral stiffness wasn’t really good enough. However, these are the second-generation, and today I’m finding out whether they’ve actually fixed that issue.
Since my first review, I’ve built a lateral stiffness testing jig, so this time we’re not relying on feel alone to measure stiffness. I’ll run Version 1 and Version 2 through the updated test, see if my original criticism holds up, and talk through what these wheels are like after over 6 months of real riding.
What’s covered: - Why the original Velo Six wheels failed my stiffness test - Side-by-side Version 1 vs Version 2 lateral stiffness testing - Real-world ride feel after 6 months - Weight, construction, and aero design - Crosswind behaviour & comfort trade-offs

In essence, be careful, do your research, and cycle safe!!!Carbon ceramic brakes on a bicycle are pretty nuts...Trace Velo2026-01-22 | Carbon-ceramic disc rotors are something you usually find on high-end supercars, but what happens when you bring that tech to road bikes? These rotors from Carbonova promise incredible heat resistance, ultra-low wear, and braking performance that doesn’t fade on long descents. But at $300 per rotor, are they really worth the asking price?
SIROKO CLOTHING – 10% off (automatically applied via link below): srko.co/tracevelo
In this episode, I’ll be diving into the incredible tech behind carbon-ceramic rotors designed by Carbonova for road bikes. I’ll demonstrate the construction and build quality, discuss how they ride day to day, and put them through real-world braking tests to see how they compare to traditional steel rotors.
The setup: I fitted these carbon-ceramic disc rotors to my endurance road bike with Shimano standard dual-piston hydraulic calipers, and ran them through everything from short city stops to long, steep descents to see how they handle heat, wear, and overall stopping power.
Why it’s interesting: Carbon-ceramic brakes are well-known in motorsport and high-end supercars for a reason. They’re incredibly durable under extreme heat, but for cyclists, the benefits may not be quite as obvious. This episode is all about separating hype from reality and showing whether these exotic rotors actually make sense on a road bike.
My thoughts: - Great braking performance, even from cold - Smooth and progressive braking, with incredible levels of modulation - Very high ceiling on brake fade - Slightly weaker initial bite compared to steel
Details: Talking with Carbonova, they are still in the very early stages, ramping up production on these rotors. They hope to start selling in late April, ready for the Spring season. Official purchases will be via the website:
http://www.carbonova.cn/
The site is currently under development and expected to launch by the end of January. I've been told pre‑orders will also be available with discounted pricing.
DISCLAIMER: While I received these pre-production prototypes to test, I haven’t been paid anything by Carbonova to feature their rotors, I’m just doing it for the love of the game baby! Also, they had ZERO say on the content of this episode.

In essence, be careful, do your research, and cycle safe!!!Carbon-Ceramic disc brakes on a road bike! #cycling #roadbike #carbonbike #newbiketechTrace Velo2026-01-14 | I've been running these carbon-ceramic disc rotors on my road bike for a few months at this point. They are made by a company called Carbonova, and are still in the testing and development phase.
They have a number of differences to regular steel rotors, not just in the braking characteristics, but also in terms of aspects like the bedding in process. They are quite expensive at around $300 per rotor, but they are certainly VERY cool.
They feel very different under heavy braking, the ceiling for brake fade is extremely high, and the level of modulation is absolutely crazy. Long form review on these coming very soon!AliExpress titanium & carbon crankset #cycling #roadbike #bicycleTrace Velo2026-01-13 | I've tried a number of cheap carbon cranksets from AliExpress over the years, some have been great, others have cracked and failed, but they all had one thing in common, aluminium axles. This is fine with SRAM DUB standard cranksets, but Shimano standard ones require a thinner profile 24mm axle, which have been known to snap or shear under high loads when made from aluminium.
However this new generation of carbon cranksets use titanium alloy axle spindles, maintaining all important lightweight characteristics, but increasing strength and fatigue resistance!Riding budget AliExpress bike parts for a whole year…Trace Velo2025-12-19 | Using parts from AliExpress & other direct to consumer Chinese brands, I’ve put together what I think is one of the best value carbon road bikes of 2025!!!

I build A LOT of cheap road bikes, mainly using parts that I've sourced from places like AliExpress. So in this episode, I’ve cherry picked some of the best parts from various builds i’ve done this year, and combined them together into what I think is one of the best value road bikes of this year!
It has a full carbon frame, tubeless ready carbon wheels, a 2x11 speed groupset with hydraulic disc brakes, and some other incredibly lightweight parts. Everything has gone through EXTENSIVE testing, and I’ve managed to build it for just over £1,600.
So in this episode I'll discuss the bike in detail, cover each part that I used (while also providing some alternative options), cover the total cost and the total weight, and finally compare it to some other name brand bikes on the market, so you can decide for yourself if my approach is worth it!

In essence, be careful, do your research, and cycle safe!!!Unlocking MAXIMUM performance from your Chinese groupset!Trace Velo2025-12-05 | Cheap Chinese groupsets from brands like L-TWOO and Sensah from AliExpress, can be VERY tempting. But out of the box, performance rarely matches Shimano gear.
However, I’ve been using these cheap groupsets on my bikes for MANY years, and believe with a few tweaks, hacks, and techniques, they can come very close in terms of performance to groupsets from SRAM and Shimano. So in this episode, I will share all my tips and tricks for squeezing every ounce of performance out of these cheaper Chinese groupsets.
I’ll cover things to look out for, ways to improve shifting performance, proper brake bleeding technique, and some general tips to ensure they run as smoothly as possible in all conditions!
If you fancy checking out any of the groupsets featured, these are the sellers on AliExpress that I personally use.

Email: tracevelouk@gmail.comThis AliExpress Bike Gadget is Pretty Incredible...Trace Velo2025-11-11 | This mechanical to hydraulic disc brake converter might be one of the coolest bike gadgets I've found on AliExpress. It’s from a brand called IIIPro (3Pro), costs less than £50, and claims to transform any old-school mechanical shifter into a fully hydraulic braking system, complete with dual-piston calipers!
SIROKO CLOTHING – 10% off (automatically applied via link below): srko.co/tracevelo
In this episode, I’ll show you the build quality, get it installed on a road bike, bleed the system, and ultimately test whether this budget hydraulic conversion kit actually works. Could this be the perfect upgrade for riders running mechanical groupsets or mechanical disc brakes like the TRP Spyre? Let’s find out.
The build: I fitted the kit to a carbon OG-EVKIN road bike frame with Micro-New mechanical shifters and Shimano 105 R7000 derailleurs to see if it really delivers “hydraulic” performance on a budget mechanical groupset.
Why it’s interesting: This idea is nothing new, the Giant’s Conduct SL system did something similar back in 2016, but this kit is lighter, far cheaper, and much easier to get hold of.
My thoughts: -Great braking performance, very close to fully hydraulic -Noticeably stronger and sharper than any mechanical caliper -A bit tricky to bleed and mount on the bike
For £50, though… this is one seriously impressive upgrade for anyone wanting hydraulic-like braking without changing their groupset.

It’s small and compact, very bright, totally waterproof, and charges via USB-C. It has a battery life of around 10 hours, and can really help add a little bit of personality to your bike!
Email: tracevelouk@gmail.com5 AliExpress Bike Upgrades - Cheap, Lightweight, & ColourfulTrace Velo2025-09-12 | Most bike tech looks pretty boring, usually sticking with black and silver. However, AliExpress has become a fantastic place to grab some really colourful parts, colour-match your bike, and personalise your ride.
All the parts I’ve chosen for my road bike build are purple, but you can find the same bits in loads of different colours to suit your own bike. Whether you want to add a few subtle touches or go all-in with a full colour theme, these upgrades let you make your road bike truly unique.
On top of the looks, many of these AliExpress bike parts are lighter than standard components, giving you a little performance boost while keeping the price super affordable. It’s a great way to freshen up your setup, stand out from the crowd, or just have some fun experimenting without breaking the bank.

In essence, be careful, do your research, and cycle safe!!!Did their disc brakes really fail? - Magene respondsTrace Velo2025-09-04 | The new QED electronic road bike groupset from the Chinese manufacturer Magene, has recently come under scrutiny after a reported disc brake failure.
In the last episode which you can find above, I discussed this reported issue, and used it as an opportunity to test a number of other Chinese disc brake groupsets that I have from the likes of L-TWOO, Sensah, and Wheeltop, for any similar issues.
Since that episode went live, I’ve been chatting with Magene, and they’ve sent over some interesting documentation. They’ve done some additional product testing, and are confident that the braking problem did not stem from an issue with the groupset.
So in this episode, I will discuss the issue, go over the evidence that Magene has provided, and give my own thoughts on the situation as a whole.

NTP composites located within the costal city of Xiamen in China, are an OEM manufacturer, making some of the fastest, lightest, and most exclusive carbon wheelsets, for some of the worlds biggest cycling brands.
I got to see the entire process, from frozen sheets of raw caron fibre pre-preg, through to cutting, layup, baking, and lacing the final wheel. It was absolutely fascinating from start to finish, and there were several steps that were completely new to me.
So join me as I uncover the secrets of carbon fibre bicycle wheel manufacture within one of China’s best factories.

Buying cheap carbon wheelsets from China does come with some risk, especially when buying from random sellers on AliExpress, that’s where this wheelset REALLY surprised me.
At £525, the cost is extremely reasonable, but the specs are INCREDIBLY impressive for this price. A 52mm deep carbon wheelset, tested in a windtunnel in Silverstone, that uses titanium nipples, with a combined weight of just 1259g for the pair!
They also come with a pretty impressive warranty from the manufacturer Upvine, and ride incredibly well, but there are some caveats to be aware of…

Buying very cheap carbon road bike wheels from AliExpress always carries a bit of risk. None of the Chinese wheelsets I have bought have failed or caused me any problems really, but it does happen.
Last year I purchased a set of tubeless carbon wheels from a brand called RYET on AliExpress for £300. However on the product page I found a review with some detailed pictures, showing virtually the same wheelset as mine, but cracked and splintered. They had apparently disintegrated or exploded during use.
So what happened to the exploded wheelset, and importantly how have my set held up over the last year and nearly 1,500 miles?

They make fully custom 3D printed bike shoes tailored to your foot, for less that £200 (€230). They use FDM printing to keep the cost low, and the entire shoe, including the liner is 3D printed... Really cool!
I also found some INCREDIBLE looking bikes! A hard tail mountain bike that is SO custom it beggars belief, and easily one of the most beautiful gravel bikes I have ever seen!
In addition, I checked out the Classified hub, with updated Shimano Di2 integration (which blew me away if I'm honest), and a relatively new groupset from TRP. It also uses the Classified hub, but in an interesting way, offering a wild 1x16 drivetrain…

Full disclosure, I have never ridden a steel road bike. My first road bike was a Claud Butler with an aluminium frame, but since then I have been lucky enough to own all carbon road bikes. However in my comments section, people always say ‘steel is real’, so I decided to find out if this is true.
The basis for the build is a cheap chromoly steel bike frame that I bought on AliExpress from a brand called Seaboard. I’ll be using a mechanical groupset from a Chinese brand called Sensah, and with external cabling, the bike should have a really back to basics feel.
So in this episode, I’ll show you how to properly protect a steel frame with Boeshield, give you a rundown of all the parts (most of which i sourced from AliExpress), show you how to build the bike from start to finish, and then give you my impressions of how it rides.

Me and a friend Alex landed in Palermo and decided to do a circular tour around the west of the island, stopping in Trapani, Mazara del Valo, Sciacca, and Corleone. I’ve done a few days cycle touring in the past, but never back to back gravel rides over a full week.
I hired a relatively premium gravel bike, a Focus Atlas 6.7 (£1,899 retail), but even so, once it was fully loaded up with a pair of panniers and all my gear, the total weight was around 26kg!
It was tough at times, the route was questionable, the roads went from lovely tarmac to rutted farm tracks without much notice, and I definitely made a few mistakes along the way, but it was an INCREDIBLE trip.
So join me and Alex as we tour around the island of Sicily, on some incredibly heavy gravel bikes!

Email: tracevelouk@gmail.comThis AliExpress bike upgrade is too powerful...Trace Velo2025-05-20 | I exclusively ride disc brake road bikes, so can this cheap AliExpress brake upgrade improve things or are they just overkill?
I have used disc brakes on my road bikes for many years at this point, and in all honesty, I have never felt like the brakes needed upgrading. The stock brakes are fine for 99% of road bikers, but I spotted some really cool looking brake calipers on AliExpress.
ZRace have just started selling flat mount 4 piston brake calipers on AliExpress, and as soon as I saw them, I had to buy them! 4 piston brakes have been available on mountain bikes for a while, but these are the first set of cheap flat mount 4 piston calipers I’ve come across, hence my excitement to test them.
Spoiler alert, these brakes are mental! SO much top end braking power, amazing modulation, and hitting brake fade is almost impossible, at least on the hill i’ve tested them on. A definite upgrade over the stock brakes, but do you really need them, and what are the drawbacks…?

Today was my last day at the Shanghai bike show 2025. It all wraps up at about midday, so I had to be quick, but I still managed to see some REALLY interesting stuff!
A few new groupsets from a brand I’d not heard of called S-Ride, 12 and 13 speed mechanical groupsets, with hydraulic brakes. The shifting was lovely, and the quality of the construction seemed very high. Now word on price unfortunately, but I cannot wait to try them.
I also saw some incredible wheels from a brand called MVMT. They had some mean looking bladed spokes, definitely the widest i’ve ever come across at around 1cm.
The microshift sword groupset was on display, so had a play around with that (although i wasn’t very impressed), I checked out some colourful new chain options from YBN chains, a new carbon crankest from Elilee, but the most interesting booth was a brand called RUFON.
They had some INCREDIBLY nice looking road bike frames, with some fantastic paint jobs. The weights were also quite impressive, and so were the prices. $1,200 is slightly more that my usual fare, but the quality was pretty impeccable, so I’m really excited to get my hands on one!
As always, today I was hosted by the INCREDIBLE Panda Podium team, so huge thanks to them, Shame from GPLama also covered some amazing new bike tech, so check out his coverage, and please check out Panda Podium for some of the best bike parts Asia has to offer!

I saw SO MUCH stuff today and interestingly got a good insight into some dealing pricing of bikes here in Shanghai. Ultimately, the cost of the entire bike here, including a DuraAce Di2 groupset, was nearly identical to the cost of just the groupset in the UK.
Tavelo had some flashy new paint-jobs for the Arow, Ridenow unveiled some lightweight titanium thru axles, and Cybrei were displaying their RIDICULOUSLY lightweight carbon crankset.
However, one of the most interesting booths was Elitewheels with their new Evolve frame. It is one of the lightest carbon road bike frames i have ever come across. For a small frame, it comes in at only 640g, and even in a large, it comes in at just under 700g!!!
I also saw a few brands that I have seen many, many times on AliExpress, like RockBros and Westbiking, and came across a promising new carbon bike brand, Rockwolf.
I am being hosted by the venerable Joe from @ChinaCycling, and his Panda Podium team and Shane from @GPLama also knocking about 🤣
But yeah, MASSIVE thank you to Joe and Panda Podium. They have been utterly incredible, so if you could check them out, it would mean the world:
Email: tracevelouk@gmail.comRIDICULOUS electronic groupsets: Shanghai bike show 2025 - Day 2Trace Velo2025-05-07 | As you may know,I cover ALOT of cheaper bike parts, mainly sourced from places like AliExpress, and naturally most of those products come from China… So what better bike show to visit!
The day one show was all about getting my bearings (the bike show is honestly HUGE), but day 2, I really tried to focus on checking out some crazy new electronic groupsets from some Chinese manufacturers.
One from a Chinese manufacturer Ningbo Suyu Transmission Technologies, a 12 speed electronic groupset that looks suspiciously like the original L-TWOO eRX groupset from a few years back (all bar a pretty monstrous front derailleur).
Wheeltop with a revised version of the EDS TX, with some new TT style shifters.
Magene with both their QED, and slightly less expensive PED groupsets.
And finally Sensah (SENTYEH), with the brand new ECS Pro, rocking a worlds first 14 speed groupset.
I also spent some time checking out new offerings from Farsports, checked out Joe from Panda Podiums’ ridiculous bike, and popped in to see OG-Evkin, the frame manufacturer that makes the bikes I personally ride.

This is day one of the Shanghai bike show, one of the world's biggest trade shows. Vendors from all over the world are exhibiting their best stuff, from a new electronic mountain bike groupset by L-TWOO, to absolutely bonkers looking chrome and gold bikes from a brand called Dragon. I tried my best to cover some of the most interesting booths at the show, and trust me, some of the stuff is unlike ANYTHING I have seen before.

Email: tracevelouk@gmail.comNo Hype, Just Real World Use - Insta360 X5, My FULL WorkflowTrace Velo2025-04-22 | The Insta360 X5 is an absolute beast of a camera, but behind all of the hype, from shooting to editing and exporting, what’s my process?
If you ask me, the quality of the footage you can get out of the X5 is pretty much beyond question at this point. 8k, super sharp, stabilised 360 footage, with nice vibrant colours. BUT behind all of the specs and the glowing reviews, what does the whole process look like, and what are these cameras like to use day to day?
I’ve been using 360 footage in my videos for YEARS at this point, so in this video, i’ll cover the new X5, but importantly, I’ll show you my full workflow. From the extra accessories I take with me, to some time saving tips capturing footage, and the easiest way to edit on desktop AND mobile.

I used to use a GoPro on a selfie stick, but it was quite difficult, and the footage was always a bit crummy. However with a 360 camera, you can get some incredible footage, incredibly easily!Mouting 360 camera to a road bike #cycling #roadbike #cameragearTrace Velo2025-04-15 | Using a 360 camera to capture ride footage is great, but you need to know how to mount it to the bike.
