Which model had the 100mm brakes? I'm pretty sure the brake size was XL (100 - 105?) and they made them a while back...I think in the black color with silver brake arms.
I can't find any online for the life of me (used of course) and have no idea why they stopped making them in this size. A jump from 90mm to 115mm is kinda stupid because there's no middle ground for people like me with a 100mm waist. I have bent fks's right now but wish I could buy a more proper fitting binding/brake from them.
