    A superlight and super strong carbon tubular aero wheel, favored by racers for the toughest classics races

    Cosmic Pro Carbon SL T was originally designed to meet the demands of our Pro teams who wanted a tubular carbon rim that would be fast over the toughest conditions, like Paris-Roubaix. So, we went through intensive testing with them, putting an incredible number of prototypes through their paces until we achieved the standards our athletes demanded. These very same wheels led Johan Van Summeren to the finish of Paris-Roubaix in first place – and now they can be yours, too.

    The carbon rims feature a unique depth to width ratio. At a height of 40mm and a width of 25mm, they are the perfect blend of high aerodynamics, low weight, excellent tire support and great strength. The 3K carbon external layer hides an incredibly complex inside lay-up using multiple types of carbon fabric that have been hand-placed for complete precision.

    Finished with the perfect wheel-tire system
    These unique rims attach to hubs that feature smooth adjustable cartridge bearings (QRM+) and our new light, fast engagement Instant Drive 360 freewheel system (convertible to any drivetrain, Shimano, Sram, Campagnolo, 9,10, 11 speed).

    Cosmic Pro Carbon SL T comes with our Yksion Pro tires. The front Griplink tire offers a confident feel while cornering thanks to its supple 210 TPI casing, and water evacuation tread pattern, coupled with a safe nylon puncture belt. The rear Powerlink tire efficiently transfers your power all the way to the tarmac, thanks to its supple 210 TPI and a carefully designed tread pattern that reduces the pressure on the ground and keeps traction at a maximum even on wet roads.

    Key Benefits:
