I like the kcnc’s, braking is great, setup was a little tricky (but again, compairing to road bike brakes). I don’t notice any sloppiness (or flex when I’m really cranking on them). I don’t have the kcnc brake levers, but got j&L’s instead. The collar is actually a mcfk road bike collar that I had lying around (don’t ask why). I plan to get a shorter black Thompson seatpost (current one is 410mm, way too long) and a different saddle to match the bike a bit better. Glad you like it, thanks!
