Slice through the wind on Roval's Rapide CLX 40 Rear Wheel. It features a 40mm-tall aero rim and DT Swiss Revolution straight-pull spokes laced to a Roval hub with DT Swiss 240 star ratchet internals. The wide, carbon rim provides a round tire profile and greater lateral stiffness for precise handling. This feathery wheel spins up with ease so you can bolt out of corners and breeze up the climbs. And, with sealed ceramic cartridge bearings, this hoop roll as smooth as glass.
