This cassette from RIRO is INCREDIBLY lightweight, and beats even the top offerings from SRAM RED and Shimano Dura-Ace. But what’s the compromise?
This road bike cassette from RIRO is a hybrid of machined aluminium, and monoblock steel. I bought it from AliExpress, and it only weighs 146g!
For context the same cassette in Shimano Dura-ACE (CS-R9100) weighs 193g, and from SRAM Red (XG-1190) weighs 161g.
Using aluminium teeth on the RIRO cassette can impact durability, but they are only used on the 2 largest sprockets. So unless you live somewhere incredibly hilly, durability shouldn’t be impacted too badly.
Regardless this cassette is EASILY the lightest one I have ever seen, so in this episode I’ll show you how it is constructed, why the aluminium teeth may not be such a bad choice, and finally provide a shifting demo.
