The concept of what makes an "attacking", all-around wheelset has been flipped with the proven attributes and real world capacity of a rim brake wheelset such as the Roval CL 50 Disc. At 1515 grams for set it is more than competitively lightweight for a disc brake aero wheel, yet carries a 50mm profile 2Bliss Ready full carbon rim that has an internal width of 20.7mm. The max external rim width is 29.4mm, which speaks to it's shaping and overall design. Roval generates wind tunnel tested, CFD driven rim shapes to account for yaw angles and tires, as well as testing with parent company Specialized's pro teams and cyclists to fully understand the variables and requirements of the road that CFD can only model.

Aerodynamically, the CL 50 Disc outperforms many deeper-section aero rims without suffering the weight and handling drawbacks associated with deeper wheels. The lightning quick response, adept and stable handling, and great rolling speed make the CL 50 Disc Wheelset a true option for the attacking cyclist who loves to climb and descend, as well as strategically breakaway from the pack, knowing the speed and efficiency needed to maintain a gap. The rim is shaped to manage the air better at the tire rim interface. It appears the design will be aero optimal with 25-28mm tires, though keep in mind wider rims can accentuate width of many tire designs, both clincher and tubeless.

Roval builds wheel systems, not wheels. Each component part (rim, spokes, nipples, hub) has been carefully chosen and optimized to work together. In other words, you can't buy a Roval rim then lace it to whatever hub you want. From and engineering perspective, spoke angles, tension, how the the nipple interacts with the rim, etc., have been developed to produce the exact performance, weight, and overall ride characteristics that each wheelset is intended for. Hence, you see the Roval AFD1 hubset, with sculpted aluminum bodies and aero flanges that are a specific height and angle to both shorten spoke length, and create the proper path to the rim. The rim has spoke hole drilling that reduces risk of damage at high tension, and factors in the head shape of the nipple and how it interacts with the rim. This is pure engineering, with each component designed for specifications in load, strength, and functionality.... Read More
