This is my first post, as I'm ready for a fixed. Be gentle. I spend most of my time over in the SS forums on MTBR.
Anyway, I am planning on building my first fixed on a track frame and I really want to use the Nitto RB-021 pursuit bars with my Thomson stem.
Problem is, the stem is a 31.8mm clamp and the bars are 26. The steerer is a 1 1/8.
Is it sketchy to use shims, or is there another 31.8 bullhorn out there that has the same dimensions as the Nitto?
