If youre attempting to put a Race Face Cinch Crankset, and its attendant 30mm spindle, into a bike with a threaded bottom bracket, youve come to the right place. Here is the Race Face Cinch BSA30 Threaded Bottom Bracket.

Race Face has designed this bottom bracket to work with English (BSA) threads. There are versions that work with three different shell widths: 68/73mmwhich is your OG traditional bb, 83mm, and 100mm. The 100mm version can also work with a 120mm wide bottom bracket, but youre sacrificing the use of the sealing sleeve between the cups.

The cups are threaded and coated with locking compound. The bearings are in sealed cartridges and covered with a dust cover. An internal sleeve seals the system on the inside. You use a traditional external cup bottom bracket tool to install. Weigh is 87g.
