Feel your bike come alive on the open road with the new Alpinist CLX IIthe 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. Theres no room for a single excess gram whether youre 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 systemhubs, rims, spokes, lacingand developing it hand-in-hand with Specialized Tubeless tires. The result is a 1250-gram tubeless wheelset with otherworldly ride quality.

The Alpinist CLX II utilizes a hooked rim (allowing for real-world riding pressures up to 110psi, if thats your thing) for secure tire bead retention and an easier set up and mounting experience than ever before. All in a wheel that almost doubles current industry impact standards while managing to achieve the lightest weight possible.

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.
