Since 2020, Rapide CLX bicycle wheels have won more World Tour races than any other wheels. A combination of the aerodynamics of deep-section TT bikes and the lightness of climbing bikes, along with the efficiency and exceptional handling of a tubeless system. They increase aerodynamic efficiency and performance on climbs, while remaining masterfully stable and manageable, regardless of wind conditions.

Side winds have a negative impact on deeper front rims, as they reduce handling and slow down the cyclist. Specialized has developed a front rim that reduces drag and increases stability by 25% in sudden side wind gusts compared to their previous 50 mm deep rims, using advanced technologies and road testing.

A wheelset that catches less drag compared to most 65 mm wheelsets and brings a significant improvement in stability by 25% compared to 50 mm rims in wind gusts, all with a weight lighter than many climbing wheels. Mission accomplished.

Engineers have developed the last rim to be reached by the wind in a shape that reduces drag on the trailing edge of the wheel. With a depth of 60 mm and an external width of 30 mm, the rear rim of this set reduces turbulence and delivers maximum aerodynamics. Since the rear wheel does not affect steering as much as the front, this deep rim does not negatively impact the overall handling of your road bike. Together, the rims represent the fastest package for real racing conditions.

The reduced rolling resistance of a tubeless setup is undeniable, as is the improved handling and incredible puncture protection it offers. The development of the Rapide CLX II rims involved the most rigorous and extensive engineering and testing program Spec' has ever conducted, resulting in a set of rims that nearly double the industry standards, while boasting the lowest possible weight.

Rapide CLX II rims are handcrafted at every step, from the initial layup to the final tensioning of spokes on the reel. The rims are built on Roval Aero Flange hubs and feature DT Swiss Aerolite T-head spokes. DT Swiss internals ensure reliability, with standard hubs of 100x12 mm at the front and 142x12 mm at the back helping to maintain stiffness when using disc brakes. The set weighs only 1520 g, offering incredible reliability, durability, and performance at a low weight.

Cassette compatibility with Shimano 11 and 12 speed sprockets.
