The Roval CLX 32 rear wheel is one of the lightest carbon clinchers ever made but this doesnt come at the expense of fundamental performance. Instead painstaking engineering & lab testing helped us achieve a 550-gram wheel thats tough enough for cyclocross racing yet light enough for the demands of a gc climber. The low inertia & ample stiffness help the wheel accelerate & change direction on a dime. We didnt skimp on aerodynamic benefits either despite this wheels low rim profile. The CLX 32 was engineered in cfd around a 26mm tire shape & honed in our very own win tunnel in order to be as aerodynamic as some rims almost twice its depth. Meanwhile the tubeless compatible 21mm-wide inner rim width better supports a tire for increased comfort & stability in corners & on descents. Lastly the wheels been outfitted with Roval aero hubs fitted with DT 240 star-ratchet internals & ceramicspeed bearings to complete the fast engaging ensemble. Truly the CLX 32 ushers in a new era of lightweight performance road wheels.
