Bottom Bracket question

jrobichaud said:

I'm restoring a 20 year old steel bike with campy components. I'd like to swap the original bottam bracket for a modern sealed one. Its a campy 70-SS, total length is 115 mm. Cups are Italian 36x24F. Not sure what would fit, in terms of dimensions. Any recommendations ?

Are the Campy cups worn? Is the spindle worn? If not, put in some new grade 25 bearing balls, add grease, install a plastic sleeve, re-install, adjust and ride on. IMO, a "modern" BB is not an improvement over what you already have _unless_ you put on lots of miles in the rain/snow/slush.

Actually, cups, spindles are all fine, plastic sleeve is cracked. Not planning op puting many miles on it. I will provbably just re-install it.

Yeah, get some new grade 25 bearing balls and a new sleeve and ride on. With decent maintainence, that BB will last forever (well, almost!).
