So I've got a Schwinn Moab, needs a threadless sealed bottom bracket because whoever put the last cartridge in ruined the threads. The problem is the threadless bottom brackets at the shop don't work. the threads don't catch when I try to screw the puppy together. I want to order a threadless bottom bracket that fit, but I don't what specs dictate the reach of the threads that grab onto left side of the cartridge. the old cartridge was L-mm110-R.

any suggestions?
