The roval clx 32 disc front wheel is one of the lightest carbon clinchers ever made but this doesn39t come at the expense of fundamental performance instead painstaking engineering and lab testing helped us achieve a 610 gram wheel that39s tough enough for cyclocross racing yet light enough for the demands of a gc climber the low inertia and ample stiffness help the wheel accelerate and change direction on a dime we didn39t skimp on aerodynamic benefits either despite this wheel39
