Roval Rapide CL II Tubeless Disc Wheel

Deep-section front rims are affected adversely by crosswinds. This negatively impacts handling, in turn causing a rider to slow down. By utilising the first modeling algorithm designed around riders’ real-world reaction times and validated by on-road testing, Specialized developed a front rim that both reduces drag AND increases stability by 25% in sudden wind gusts compared to their previous 50mm rims.

The rear wheel is the last thing the wind sees, so Specialized developed that rim shape to minimise drag at the trailing edge of the bike. At 60mm deep with a 30mm external width, the Rapide CL II rear rim reduces turbulence and yields the greatest aerodynamic benefit. Since the rear wheel doesn’t affect steering the way the front does, this deep section doesn’t adversely impact handling. Together, they represent the fastest package for real-world race conditions.

The Rapide CL II is hand-built every step of the way, from the initial lay-up to the final tensioning on the nipples. Built on DT Swiss 350 hubs with 36t Star Ractch and Competition Race straight pull spokes, the result is a set of wheels designed as a complete system that weighs just 1590 grams a set, delivering incredible reliability, durability, and performance.

The reduced rolling resistance of a tubeless setup is undeniable, as are the benefits of improved handling and incredible puncture protection. The development of the Rapide CL II involved the most rigorous and extensive engineering and testing program Specialized have ever undertaken and resulted in a wheelset that almost doubles current industry impact standards while managing to achieve the lightest weight possible. The Rapide CL II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi, if that’s your thing) for secure tyre bead retention and an easier set up and mounting experience than ever before.
