Race Face BSA 30

The Race Face BSA 30mm Bottom Bracket was made to work with their 30mm Cinch interface system. The Cinch system uses a 30mm spindle to provide a stiffer bottom bracket/crankset interface, but previously this would limit you to BB30/PF30 frames not with Cinch! These new BSA 30 bottom brackets will allow you to fit your Race Face Cinch 30mm spindle crankset in a standard threaded bottom bracket. Don’t let your bottom bracket shell width keep you from experiencing 30mm spindles!
