The Cosmic Pro Carbon was originally used primarily for fast, flat races, but incremental improvements have given it the versatility it was once missing. At only 1690g with a 45mm deep rim, this wheel system now offers the perfect balance of lightweight and aero efficiency. The new 25mm wide rim shape is NACA compliant for low drag and excellent crosswind stability. It’s an innovative hybrid of alloy and carbon, using the best qualities of both materials. The alloy rim core is ISM (Inter Spoke Milling) machined to remove excess material between each spoke, which minimizes weight. The carbon rim flanges improve aerodynamics by increasing the rim depth and lowering drag. This is much more than a fairing—it’s a structural part of the wheel that adds the lateral and frontal stiffness that racers crave. The rims are laced with our patented aerodynamic spokes, saving another few watts. The Cosmic Pro Carbon comes with 25mm Yksion Pro tires for improved rolling efficiency and comfort. The front GripLink tire features a supple 127 TPI casing reinforced by a strong Kevlar anti-puncture belt. The tread pattern is optimized for cornering, even on wet roads. The rear Powerlink tire also has asupple127 TPI casing and a light nylon anti-puncture belt, along with a specific tread pattern for super low rolling resistance. The wheels come with white or grey decals, but can also be ordered using our customized decals service.
