As a standard, THM cranks use a 30mm spindle. In order to satisfy an ever growing market of new bottom bracket standards, THM has created several BB’s to be used with their Clavicula, M3 cranks, and 68mm wide mountain bike cranks in the following bottom bracket shell sizes. Select THM bottom brackets are available with hybrid ceramic bearings.

BSA English - Fits standard sized bottom bracket shells with English facing threads.

**Please note that THM is changing the anodizing on their BSA cups. All newer cups will be coming in black. We still have a couple of silver sets in stock so get them while they are still available.

Italian - Fits standard sized bottom bracket shells with Italian facing threads.

BB30 - Fits oversized BB30 frames.

PF BB30 - Fits oversized BB30 frames, which are specifically Press Fit.

BB Right - Fits Cervelo’s BB Right bottom bracket standard.

Shimano PressFit - Compatible with BB86.

SBI PF30, Carbon OSBB Specialized's - (SBI) PF30 and OSBB standards are unique to some models of Specialized bikes. In other words, the PF30 on a Specialized is not the same PFC30 on another bike.
