Mavic wheels have been a staple of road cycling for decades. Our ceramic bearing kit modernizes your Cosmic or Ksyrium hubs with Grade 3 silicon nitride balls and DLC-coated races. Mavic's Instant Drive 360 or FTS-L freehub systems benefit directly from the lower friction — faster engagement, smoother coasting, and dramatically longer bearing life. The most cost-effective upgrade you can make to aging Mavic wheels.
