Those Tricky Tricky Bottom Brackets
so I've trolled the forums and found no luck so here is my problem..
I have a late 80's Saintropez "La riviera 440" frame, and it has a mystery bottom bracket.
I know that It is not Italian, and no 35 x 1 stamp on the OG cups..so not french, it's pointing towards English threading, but I bought a Shimano UN25 cartridge BB and the removable cup threads perfectly into both sides but the actual cartridge itself wont engage the threads in the least. It also seems to sit funny in the BB shell (the spindle is not centered in the shell on the non drive side)
help please I'm bikeless until I can figure it out
