Bottom Bracket bearing size?
I just found a square taper Shimano NJS bottom bracket today at a garage sale (thanks Judah!) The BB didnt come with bearings and so I ask you: Is there a standard for this sort of thing? 1/4"? All the rest of the measurements are in metric (68mmx107mm)so it seems weird that it would be imperial. Anyways thanx.

Well, a Dura Ace hub is metric like his BB and it uses 1/4 bearings.......
The Dura Ace hub uses 9 bearings on each side and it is a bit smaller than a BB race so 11 bearings do not seem excessive.
I think it is pretty relevant
