M30 Thru BB Conversion (BB30/PF30) 73mm MTB

The Praxis Works M30 Thru bottom bracket features a patent-pending threaded design that eliminates the common creaking and tolerance issues found in BB30 and PF30 mountain bike frames. By threading the drive cup directly into the non-drive cup, the internal collet system expands to create a rock-solid, even fit. This unique construction keeps the premium Enduro 6806 cartridge bearings positioned outboard, significantly increasing frame rigidity and drivetrain efficiency.

Designed for high-performance 30mm spindle cranks, this bottom bracket is fully compatible with Praxis Lyft, Race Face Cinch, and Rotor REX systems. The assembly includes a sleeve for BB30 installations and uses high-grade grease to ensure long-lasting, smooth rotation in harsh off-road conditions. Engineered for 73mm shell widths, it provides a precise, professional-grade solution for riders who demand a quiet and reliable mountain bike setup.
