Feel your bike come alive on the open road with the new Alpinist CLX II—the lightest, best-handling clincher wheels we have ever made. Hyper-responsive acceleration, magic in the corners, sublime over rough roads, all elevated with the performance of a tubeless system. There’s no room for a single excess gram whether you’re chasing summits or ride quality because perfection is only achieved when there is nothing left to take away.
It takes more than a lightweight rim to deliver the incredible reactivity and handling of the tubeless Alpinist CLX II. The wheelset is designed as a system with our engineers controlling and testing every part of that system—hubs, rims, spokes, lacing—and developing it hand-in-hand with Specialized Tubeless tires. The result is a 1250-gram tubeless wheelset with an otherworldly ride quality designed for real-world road pressures.
The Alpinist CLX II rim is a work of art. It features the most precise carbon layup we have ever created, the result of over 50 different iterations, hundreds of impact tests, and countless hours on the road. They react to even the slightest increase in power with immediate acceleration and carve the purest of lines in the corners, yet they can also handle almost double the impact standards of every certifying body. This is instant acceleration and supreme durability, two years in the making.
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 that we’ve ever undertaken, along with two years of exhaustive real-world evaluation to reach the point where we can say that road tubeless is ready for prime time. As a result of this extensive development, the Alpinist CLX 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. This is tubeless done right.
Our all-new LightAF hubs are the spinning heart of the Alpinist CLX II. We carved 50 grams out of the previous Alpinist CLX hub with new low-profile hub bodies and machined rotor mounts. Inside, DT Swiss EXP internals and SINC ceramic bearings deliver silky-smooth efficiency and outstanding durability.

The right tire pressure has a huge impact on the quality of your ride. What you see below are recommended starting points. Tire pressure is personal and depends on your riding style and the terrain you'll be riding so don’t be afraid to experiment to find your perfect pressure, but never exceed the max pressure indicated on your rims. Enjoy your ride!
• Pressure ranges listed below are based on the rear wheel. Ride 0.3 bar /5 psi lower in your front wheel than rear.
• From these recommendations, adjust up and down in 0.2 bar/4 psi increments to find your ideal pressure.
• For wet conditions, improved traction, or more comfort drop tire pressure 0.5 bar/7 psi on both wheels.
• Never exceed the tire pressure limits of either the rim or the tire.
