BB for my Cannondale
I have a Cannondale R700 1997 with Shimano 105 Crank
After having some noise from teh crank/bb area i reoved the crank and the BB
The BB is a Shimano BB-UN52 68 BC1,37x24
Whemn i look at webpages for a replacement i have the option for
Shimano compatible. 251g. (68x107mm). Specify Model: 68x107, 68x110, 68x113 or 68x115mm.
witch one to get?
messure the axle with a ruler . my guess would be like a 113 mm should do it.
infact it was a 107
.... i am wondering ... i like this bike a lot .. and would like to upgrade it it has 105 and ultegra now
from 1996 with lots of miles on salty west norwegian roads .. if i buy a new ultegra sl .... does the new BB have to be a 68/107?
yes with your question , but if you are going with new stuff (08) then it will be external cup and bearing units. then the axle would be longer .
