The Mavic Ellipse is a race-proven, high-performance wheelset for competitive velodrome racers and urban fixed gear riders who want max-level speed with everyday durability. Featuring 30mm deep Maxtal® aluminum rims with welded SUP joints and Mavic's black Exalit brake track for stealthy rim brake compatibility, QRM+ sealed cartridge bearings, a low spoke count and wide bladed straight-pull spokes, the Ellipse wheelset delivers reliable aerodynamic efficiency, swift acceleration and superior strength. ⓘ The lockring included with this wheelset uses a proprietary French threading. We sell genuine replacements, but no other lockrings are compatible.
