Hey guys,
I was doing some maintenance on my vintage track bike's bb, and when I was re-installing it the lockring/adjustable cup interface stripped. Anyone know where I can find a replacement italian-threaded bb (or just the cup/lockring) for a stronglight track crankset from the 70's?

Here try this link https://www.sheldonbrown.com/harris/f...s.html#bottom2

Is it just the lockring that is stripped? Any Italian thread lockring will work.

No, it's the cup that stripped unfortunately. I checked harris but they only have french threaded replacement cups. I'd replace the whole thing with a cartridge bb but I'm not sure what kind of spindle these cranks take, JIS or ISO.

I replaced the bb and the cranks as well. I used SRAM Apex. had to buy italian threaded bb separately. I have the stronglight italian threaded bb but I won't sell just the lockring, only the entire set. Let me know if you want it. 2 cups, spindle, lockring, left crank, right crank. make an offer.

AFAIK, Stronglight never made a JIS spindle. If Stronglight worked before, an ISO taper cartridge ought to be fine.
