  • Cosmic Pro Carbon SL UST Disc

    The super fast Cosmic Pro Carbon SL Disc now goes even faster thanks to the added benefits of Road UST Tubeless.

    Road wheelsets are delivered as Wheel-Tyre system

    To make the most of punchy terrain, with repeated short steep climbs, twisty descents and fast flats, any high-end race bike with disc brakes should be set up for speed. And for the truly competitive, this Cosmic Pro Carbon SL C Disc is the go-to carbon clincher disc wheelset.
    The unique rim design makes it super strong, while its unique shape also provides:

    • Extremely low rolling resistance and high comfort thanks to a wide 19mm inner rim that perfectly complements the 25mm tires
    • The best aerodynamic performance in the category, meaning low drag and superior crosswind stability thanks to the 25mm wide NACA profile that perfectly suits the 25mm tire shape

    Smart modifications for disc brakes
    Because 90% of the rider’s weight is transferred to the front wheel when braking hard, we’ve beefed up the front wheel with a higher spoke count (24). The spokes are also crossed on each side of the hub to perfectly transfer the braking load to the ground with no loss of stiffness and no wheel wobbling, keeping you perfectly in control.

    Finished with the perfect wheel-tire system

    The new UST Tubeless compatibility further reduces rolling resistance, while increasing comfort and flat protection and reducing the whole system weight. It also offers a front triple-compatible hub, so you can easily fit it to any fork. The wheel comes in 12mm, and converts to quick release and 15mm through axle fork with optional adapters.

    On the rear wheel, we’ve gone for maximum power transfer and rolling efficiency. The 24 spokes, using our Isopulse lacing (radial on the drive side), make for an incredibly smooth transfer of energy. We also use our brand new Instant Drive 360 hub, which offers low friction, instant freewheel engagement at only 9° and total compatibility with any kind of frame retention system: delivered in 12x142, they convert to quick release with optional adapters. The rear clincher tire is a Yksion Pro Powerlink in 25mm. It offers a high rolling efficiency thanks to its 127 TPI casing and specific center grooves on the tread pattern that reduce the pressure on the ground giving higher speeds and superior traction in wet conditions.

    Cosmic Pro Carbon SL C Disc is available for 6 bolts and Center Lock rotor and Shimano / Sram cassettes. Convertible to Campy or Sram XD with optional driver bodies.
