Mavic Front hub MR801INFSPRR CL XDR 24H

The MR801 INFINITY SP hubs are the worthy successors of the best historical Mavic hubs (501, 571…) and feature our latest innovations.

The Infinity design is Mavic's latest hub innovation, featuring a lighter build, straight pull spokes and contact-free spokes, better spoke tension balance, the same spoke length all around, and the renowned ID360 freewheel system. Infinity has it all and is now available for your custom build!

The ID360 freewheel's ratchet provides quick engagement and optimal torque transfer, reduces drag, and offers great ease of maintenance. It’s compatible with all types of cassette bodies (classic Shimano and Campy 9 to 12 speeds, XDR, N3W).

The precise CNC machining of the hubs optimises the alignment and arrangement of the spokes for stable, robust, and long-lasting builds.

The large sealed cartridge bearings (2 at the front, 4 at the rear) feature a C3 internal clearance for smooth operation and long durability.

Our QRM Auto automatic bearing adjustment system ensures perfect play and flexibility without needing any adjustment from you.

This road version is compatible with all major frame/fork axle systems: 12 x 100, 15 x 100, 12 x 142, and quick release.

Designed, developed, and tested in France, with CNC machining done in Europe.
