Feel your bike come alive on the open road with the new Alpinist CL II featuring the lightest best-handling clincher rims we have ever made elevated with the performance of a tubeless system. The brand new Alpinist CL II now brings mountain-taming performance slightly closer to Earth with a carefully selected build designed to let riders take full advantage of the low rim and spoke mass. The Alpinist CL II utilizes the same rim as the Alpinist CLX II. They react to even the slightest increase in power with immediate acceleration and carve the purest lines in the corners yet they can also handle almost double the impact standards of every certifying body. The result is a 1375-gram tubeless wheelset with an otherworldly ride quality designed for real-world road pressures. The Alpinist CL II utilizes components curated to keep you rolling and rolling fast. The DT Swiss 350 hubs featuring their Star Ratchet drive system are reliable and easy to service while 24 DT Swiss CompRace Straightpull spokes front and rear laced to the rims with their alloy Pro Lock nipples are synonymous with reliability and can be obtained at any bike shop. The reduced rolling resistance of a tubeless setup is undeniable as are the benefits of improved handling and incredible puncture protection. It took the most extensive and demanding engineering and testing program we’ve ever undertaken. As a result of this extensive development the Alpinist CL II features a hooked rim that can handle a huge range of pressures up to 110psi and offers an easier set up and mounting experience than ever.

The all-new Rapide CL II wheelset brings the Rapide CLX II’s speed efficiency incredible handling and stability in any conditions to more riders. Built on the exact same rims as the Rapide CLX II to elevate all this performance with tubeless-done-right technology the Rapide CL II makes that performance easier to catch at check-out and you almost impossible to catch on the open road. Deep-section front rims are affected adversely by crosswinds. This negatively impacts handling in turn causing a rider to slow down. By utilizing the first modeling algorithm designed around riders’ real-world reaction times and validated by on-road testing we developed a front rim that both reduces drag AND increases stability by 25% in sudden wind gusts compared to our previous 50mm rims. The rear wheel is the last thing the wind sees so we developed that rim shape to minimize 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 we’ve 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 tire bead retention and an easier set up and mounting experience than ever before.
