Praxis M30 BB30/PF30 68mm Road Bottom Bracket – M30 Road Crank Compatible

The Praxis M30 BB30/PF30 68mm Road Bottom Bracket is engineered to install Praxis M30 alloy spindle road cranks into 68mm BB30 or PF30 road frames. Built for precision, smooth pedaling, and durability, it features forged and machined heat-treated alloy cups and high-quality cartridge steel or ceramic bearings for long-lasting performance.

The bottom bracket uses a 30mm drive / 28mm non-drive bearing configuration, with a drive-side wave washer to preload the bearings for optimal smoothness and alignment. With the Praxis Collet Design, this BB ensures a secure and precise fit. Average weight: 130g.

Installation requires a press tool/drift along with M30 Socket Tools or M30 Wrench Tools.
