Can anyone tell me where to buy LH threaded BB lockrings? These would be for BB's like Galli, Omas, and I think some Stronglight models, that use adjustable cups on both sides. This allowed some chainline adjustment as with Phil BB's. I used a Galli BB on the 50th Anniversary Paramount, but it had no lockrings, so I had to steal them off another BB. I think one would need the LH lockring only on English/ISO BB's. The RH cup on French and Italian is RH thread, so the same lockring works on both sides. I suppose a Swiss BB would need a LH lockring also, but I would think extremely few BB's of this type were ever made with Swiss thread. Fortunately, I don't need to find a lockring for one of those.
