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