With a lighter weight 65mm rim and easier to use Road Tubeless technology, this carbon disc-brake wheel delivers lightning fast speed and efficiency for road racing and triathlons. The Cosmic name has always been synonymous with speed and performance. This 65mm version for disc brakes is no exception, and it’s the fastest of the family when it comes to hammering the flats and in the wind. The 65mm deep airfoil rim slices through the wind with minimal drag, and its 26mm wide profile makes it highly stable in crosswind. It also uses our patented elliptical spokes that save another 5 watts to maximize your efficiency. Another key factor in efficiency is rolling resistance, which we address with our updated UST Road Tubeless system that makes it easier than ever to mount and change tires. No tube means no friction, and more air volume means a smoother, faster ride. Exclusive Fore Carbon technology attaches the spokes to the rim without the need to drill the upper rim bed. With the new rim bed shape, no tape is needed, eliminating any hassles and saving 30g per rim. We further lowered the weight of the rim with a new laminate and local reinforcement. Our Infinity hub platform optimizes spoke lacing and tension for maximum power transfer. The Instant Drive 360 freewheel, coupled with automatic bearing preload (QRM Auto), provides fast engagement, high stiffness and added durability. It's available with Shimano or SRAM XD-Road driver bodies and converts to Campagnolo with an optional driver body. It's compatible with 12x100 axle up front, and 12x142 rear, and can convert to Quick Release with supplied adapters.
