Building up a Poprad (first build-up on my own), how do i figure out what size BB I need?
Also, installed Avid Shorty 6 canti's and for some reason there is a small amount of front to back play on the arms despite the bolt being fully tightened. Do I not have them set properly, is there a compatibility issue, or should a simple additional washer on the bolt fix the problem?
Thought I'd simply be able to port all the components from my too small bianchi axis to the poprad but i'm now learning the nuances of part specifications!!
The Poprad uses a standard 68x109 (double) or 69x118 (triple). Sound to me like you are missing a washer on those brakes - maybe the one with the half-moon cutout that seats it against the frame? If not, just add a thicker one until it tightens up.
