Welcome to the Mavic website

This is the secret weapon for fixed gear racers. Anyone committed to racing ultra-fast and highly technical street criteriums such as the famous Red Hook series demand wheels that deliver speed, reliability, and even more speed.

These wheels were developed with racers who initially rode our proven Ellipse training wheels, a standard for velodrome and fixed gear winter training. In an effort to elevate those racers’ performance possibilities, we tested various rim depths, spokes and lacing styles in tubular, clincher, and then UST Tubeless. That process led to the Ellipse Pro Carbon UST.

The 64mm deep Comete Pro Carbon UST rims are laced up with 20 patented steel aero spokes on our sturdy Ellipse hub. The rear hub is flip-flop style, so you can mount one cog on each side and make quick gear ratio swaps according to the racecourse or terrain.

Main features

Aerodynamic and stiff for speed and acceleration

64mm deep full carbon NACA rim profile
26mm wide, optimized for 25mm tires for low drag and high crosswind stability
20 flat straight pull spokes, laced 3x, for high lateral stiffness

Fast and efficient on straights, more control when cornering

UST eliminates tube friction for less rolling resistance
UST lets you ride with lower tire pressures for improved grip in the corners

Easy to set up and maintain for daily training or race use

Simple tubeless tire set up and high puncture protection
Flip-flop rear hub lets you use 2 cogs on the same wheel for more versatility
