I've got an earlier model Zebdi (not sure which version), and my brake bosses are something like 111mm from c-c. I just recently got a Shimano Carbon booster and found out it doesn't fit, widest point is 103mm. Has anybody had this problem and what have you done about it? I can't seem to find any boosters wide enough. Has anybody made their own? suggestions? thanks btw, I have searched for a while and not found anything helpful
