The DV46 C UL provides identical performance to the DV46T UL but with Reynolds' propriety, patented all-carbon clincher technology. The deep-V rim improves flat-out speed, and combines it with lateral stiffness and durability 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 sure. 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 worlds fastest carbon clincher.
