Praxis M30 BSA Bottom Bracket

Praxis based the new Turn cranks on the Praxis M30 ‘Wide-Stance’ platform. The M30 bottom bracket uses one spindle for three of the most common bottom bracket frame standards in the market. The Praxis Turn M30 bottom bracket is available as English threaded frames, BB86/BB92, or in the very popular Praxis Conversion for BB30 or PF30 frames. This design keeps the cartridge bearings outboard the frame free of frame tolerance issues and keeps the bearings aligned for longer wear and noise free riding. One crank, with proper bottom brackets’s for compatibility across many frame types.

Larison Rebuilding a vintage Cannondale mountain bike and needed to upgrade crank. The M30 standard provides a wide, externally mounted, sealed bearing configuration that supports a variety of Praxis Cranks. Bracket came prepped with thread lock to avoid creak and misalignment. Bracket installed easily, works well, and looks great.
Mr Thomson Required to install Praxis Works sub-compact chainset to my Croix de Fer. Quality part, clear instructions, just remember you need the Praxis tadapter to tighten as it’s different to Shimano standard.
