2019 Specialized Roval CL 50 Disc Wheelset

The Specialized CL 50 Disc Wheelset has been designed to fill a gap in the market for a truly race-ready, affordable carbon wheelset. The CL 50 Disc Wheelset uses the Specialized CLX 50 Disc rim with DT Swiss Competition round spokes, Specialized Aero Flange Disc hubs with DT Swiss 350 internals, and steel bearings to deliver you an exceptional wheelset at a more than accessible price. Why disc you ask? With Specialized disc-specific rims, you not only ditch the brake track, but you get a stronger, more impact-resistant rim. This comes at the hands of a disc-specific carbon layup that optimizes stiffness and keeps weight as close to its rim-brake brethren as possible. And all the while, you get incredible brake modulation and power in all conditions. Sharing rims with the CLX 50s, the CL 50s feature many of the benefits as their higher-end siblings. Even though the CL 50 is similar in weight to many wheels in the โ€œlightweightโ€ category, aerodynamics came at the forefront of the development. With this, Specialzied jumped headlong into Computational Fluid Dynamics computer modelling to arrive at various rim shapes that could make the CL 50 as fast and light as possible. It took a while, but Specialized narrowed the rim shape down to three contenders that were then CNC machined into rims, built into wheels, and put into the Specialized Win Tunnel. The result? A 50mm-deep, 1515-gram clincher wheelset that’s race-ready and wallet-friendly.
