Praxis Shimano Road BB30/PF30 68MM Bottom Bracket
The Praxis Shimano Road BB30/PF30 68MM Bottom Bracket is designed for Shimano Hollowtech II cranksets. The Praxis Shimano bottom bracket uses a rubber elastomer that expands within the bottom bracket shell when installed to lock the bottom bracket in place. This bottom bracket is designed for frames that use a BB30 or PF30 68 mm (road) bottom bracket shell.
This bottom bracket also features a sleeve for both BB30 and PF30 shells. Riders installing this on for a BB30 frame can remove the PF30 sleeve for proper fitment. It requires two 16 notch, 44 mm internal diameter bottom bracket tools in addition to a bearing press for installation.
