Are you looking for period correct BB set or just a new American
Sealed set? I upgraded my Pro Racer with my original Sugino GT 3-piece
set with a Tioga sealed bearing conversion kit. Tioga #CK-170SB, it
comes with a new spindle(standard square taper) cup set and bearings
and it's own wrench. It's 80's NOS, the person I bought it from sells
on e-bay under Earlstuff. He has a huge warehouse of NOS bike parts
only a few miles from my house. I can see if he has more. I think I
paid around $35-40 for it. You can also try contacting him through e-
bay he has his e-mail on his auctions. Otherwise Dan's Comp has one
for $29.99 on the website that would probably work part #455021.
Standard American/127mm comes with everything needed. Hope this helps.
