Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

BB for vintage dura-ace track cranks?

Any ideas as to what a good bb would be for vintage dura-ace track cranks? My old one was 103 or so but had some bad pitting when I went to service it. Time for a replacement. It would be used with 120mm drops. Like to keep the cost low but quality high of course. I just found a 110m bb shimano UN72 for $10 brand new..would it work. Just need some advice from more experienced people.

Thanks!

Depends on which series you have. I have the older 7500 cranks, kind of Campy style-fluted arms and spider, and a 107mm BB.
