The MR801 are the worthy successors to Mavic's best historical hubs (501, 571…). The millimeter-precise CNC-machined hubs optimize torsional stiffness and spoke alignment for stable, robust, and durable setups. The large, sealed cartridge bearings (2 in the front, 4 in the rear) feature an internal clearance of C3 for smooth operation and a long lifespan. Our automatic bearing adjustment system QRM Auto ensures perfect flexibility and play without any adjustments on your part. The ID360 ratchet mechanism of the freehub offers an engagement point of just 9° and optimal torque transfer, reducing resistance and creating a pleasant sound when the wheel spins freely. The disc brake version is available in 24, 28, or 32 spoke holes (front and rear). It is compatible with a 12 mm diameter axle and can be easily converted to a thru-axle.
