OK, another unscientific video for comparison to my prior one you can see here:
youtu.be/SI477AeLb-o

I finally got my bike back from the shop (long story involving crashes and COVID …). Anyway, the shop installed the Race Tech springs front and rear, and set the “race sag” on the rear for 4” @ 240-245lbs (that’s about what I weigh with all off-road gear on).

Specs for the springs:
Rear: 6.0kg/mm
Front: .52kg/mm

I believe that combo of spring weights serves up to about 270lbs with preload set properly. IIRC I fell roughly midway in the compatible spec. Race Tech has a good table to help you pick a spring weight. Best to look there! :-)

Note: I was not present to set the sag, but the shop’s owner goes roughly 240-ish, and they used his weight to set it. This is not an exact science, and on any given day I might not be wearing 25-30lbs of riding gear, or I might be wearing that gear and also have bags on. I figure I’ll be adjusting the sag at some point, and I have not even begun to dig into clicker settings.

PS: I NEVER ride as clothed there, though!! Haha.

PPS: I realize this angle is not the best, but I wanted to keep it about the same as the stock video.
