Praxis M30 Service Kit

Engineered Precision. Stepped-Spindle Performance.

The Praxis M30 Bearing Kit is designed specifically for Praxis M30 BB30, PF30, and Specialized OSBB configurations. By utilizing high-grade chrome steel bearings with a specialized internal grease fill, Praxis has created a replacement kit that thrives under high-torque climbing and high-cadence sprinting, ensuring your power transfer remains absolute and noise-free.

Why the BR-3028 Kit is a Performance Essential:

• Stepped-Diameter Architecture: Includes the specific 30mm (Drive Side) and 28mm (Non-Drive Side) bearings required for the patented Praxis M30 interface, eliminating the need for sloppy adapters or shims.

• High-Load Chrome Steel: Forged from premium chrome steel for maximum durability and resistance to pitting, ensuring a long service life even for high-mileage endurance riders.

• Advanced Labyrinth Sealing: Each bearing features dual-lip rubber seals designed to act as a fortress against water, road grit, and salt, keeping your internal grease clean and frictionless.

• Quiet-Drive Technology: Engineered to eliminate the "creaking" common with press-fit systems by providing a high-tolerance, snug fit within the Praxis M30 carrier cups.

• Professional Grade Grease: Pre-packed with a specialized high-pressure lubricant that resists "wash-out" during rainy rides or bike washes.

• Complete Refresh Kit: Includes both the drive and non-drive side bearings along with the necessary seals and dust covers for a total bottom bracket overhaul.

The Alegro Perspective: In the shop, we call the M30 system "the mechanic's choice" for press-fit frames. It’s an incredibly smart design, but because of that unique 28mm non-drive side, you can't just throw in standard 6806 bearings. The BR-3028 kit is the only way to do the job right. If you’ve started to feel a slight "crunch" in your pedals or heard the tell-tale click of a worn bearing, this kit will make your bike feel elite again for a fraction of the cost of a new crankset.
