This is a French (or Swiss) threaded Bottom Bracket for use with 24/22mm axle cranksets (SRAM GXP compatible). It comes as a 24mm (Shimano Hollowtech II) bottom bracket plus a 24 to 22mm converter kit to make it GXP compatible.
Millions of vintage bikes have French threaded or Swiss threaded bottom brackets. Used and new square taper bottom brackets are still available, but there is (almost) no solution to install a modern crankset with a 24mm or 24/22mm spindle on those frames.
Our BB is custom produced by a respected Taiwanese producer and uses quality steel bearings.
The French threaded BB uses 35x1mm metric threads right-handed on both sides.
The Swiss threaded BB uses 35x1mm metric threads a right-hand thread on the left and left-handed on the right (to avoid the cups to unscrew themselves).
