Do touring bikes of the 80's as a general rule (by design) have a lower bottom bracket height? Should I eliminate 80's tourers from my search as possible candidates for a 650b conversion?
TIA
Some touring and sport touring bikes from the 80's have higher bottom brackets than others. Miyata and many bikes made by the such as Univegas and some Specializeds had higher BBs than Treks.
Weinmann and Dia-Comp 750 centerpulls have sufficuient reach on many frames built for 27" tires. It all depends on where the holes in the fork crown and the rear brake bridge are.
