M30 Thru BSA Bottom Bracket - Silver

The Praxis Works M30 Thru BSA Bottom Bracket is a threaded BSA bottom bracket built for riders running 30mm-spindle cranksets on English-threaded frames, with a focus on precise fit and dependable bearing performance. With 30mm drive-side and 30mm non-drive-side bearings, it’s a clean solution for modern crank compatibility while keeping the serviceability and creak resistance many riders prefer from threaded systems.

• BSA threaded interface - Prioritizes straightforward installation, repeatable service, and a secure threaded fit for compatible frames
• 30mm drive / 30mm non-drive bearing layout - Supports 30mm spindle crank applications while maintaining proper alignment through the shell
• Broad 30mm crank compatibility - Intended for Praxis Lyft cranks and compatible with SRAM 30mm spindle, Race Face/Easton Cinch, Rotor REX/3D+ 30mm, 5Dev, and Cane Creek eeWings cranksets
• Enduro bearings + high-grade grease - Built with quality internals chosen for smooth rotation and long-term reliability under real-world riding conditions
• Correct tool requirement - Requires the Praxis M30 BB tool for installation; for versions with external cups use PX8980/8981
• Silver finish - Clean, workshop-friendly appearance that matches a wide range of builds
