The identical performance of the DV46T UL but with our acclaimed, one-piece clincher design. The deep-V rim improves flat-out speed, and combines it with lateral stiffness and strength for tenacious handling on a sketchy descent or in a bunch sprint. The DV46C UL incorporates a continuous section of Ultralight (UL) unidirectional carbon fiber material with a carbon braking surface, so response is quick and solid. Braking performance on short and long descents is improved by up to 17%, thanks to more effective heat dissipation. Our Vibration Management System (VMS) reduces vibration down to the bare minimum. When it’s time to start kicking up the wattage, you’ll be glad you’re riding the world’s fastest carbon clincher.
