When Specialized set out to create a wheelset built purely for speed, they wanted to make it more than just fast. Not that being fast wasn’t a priority, but Specialized was tired of wheels that only performed well in a straight line. In the end, Specialized developed the Roval CLX 64 Carbon Disc clincher wheel, the fastest wheel that Specialized has ever tested with all of the performance benefits of disc brakes that we have come to love. This iteration has a more impact-resistant rim, a disc-specific carbon layup that optimizes stiffness and weight, and incredible brake modulation and power in all conditions.
