The Praxis M30 thru bottom bracket is engineered to deliver exceptional performance and reliability for mountain bike enthusiasts. Designed specifically for optimal compatibility with the Praxis Lyft Carbon Crank, this component ensures a seamless and durable fit that enhances your riding experience. It also supports RACE FACE "CINCH" and Rotor "REX" MTB cranks intended for 73mm BB30/PF30 mountain bike frames, making it a versatile choice within the mountain bike category. Its patent-pending design positions Enduro cartridge bearings outside the frame, significantly improving stiffness and eliminating common issues related to frame and c-clip tolerances found in other bottom bracket systems.
Installation is engineered for precision and ease. The longer non-drive cup is pressed in first, followed by threading the shorter drive cup into place. As the drive cup tightens, the innovative Collet system expands evenly to a precise limit, distributing pressure uniformly to ensure a rock-solid fit. This mechanism guarantees the bearings remain perfectly aligned without risk of movement or misalignment during demanding rides. Additionally, a compressible o-ring on the non-drive side cup compensates for slight variations in frame shell width, providing a consistently perfect fit across compatible frames.
Is this bottom bracket suitable for different rider sizes or preferences?
The Praxis M30 is compatible with a range of MTB cranksets designed for 73mm BB30/PF30 frames, accommodating multiple configurations without restricting rider size or preference.
