Praxis M30 Thru Road BB30/PF30 68MM Bottom Bracket
The Praxis M30 Thru Road BB30/PF30 68MM Bottom Bracket is designed for 30 mm spindles. It uses a rubber elastomer that expands within the bottom bracket shell when installed. This helps ensure that the bottom bracket is locked in place. This bottom bracket fits frames that use a BB30 or PF30 68 mm (road) bottom bracket shell.
In addition, this bottom bracket features a sleeve for BB30 shells and a sleeve for PF30 shells. Riders installing this on for a BB30 frame can remove the PF30 sleeve for proper fitment. It requires two Praxis M30 Bottom Bracket Socket Tools for installation and removal.
