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 otherworldly ride quality.
The Alpinist CLX 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. 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.

Everything was great. Was waiting for the SL9 to release since the first leak. Going from a SL7 was night and day.
Also Sierra Bicycle Supply, was amazing. Will be shopping here plenty more. The service they displayed was top tier, from the order placing online all the way to the delivery.

Exceptional Wheels
The CLX III are exceptional I was a little apprehensive about buying them having ridden the Enve 4.5 but you feel less crosswinds and their lighter and spin fast. The spokes seemed to offer a lot of dampening vibration. Win win in my book.

After many years I wore out my derailleur gears. Since I ride on my wind trainer daily, I needed to get up and riding again. Riding us part of my cancer therapy. Replacing the gears was a quick and easy way to fix the problem. Cost was fine and the delivery was fast. Thank you.
Got this for my kids bike. He does XC racing. Has been riding in dry lose dirt, wet conditions. Lots of climbing and some downhill. He loves them. Shipped fast and in sexure packaging. I would definitely buy again.
Heard a lot of good things about this tires put them on my commuter. The roll much faster than the schwable energizers on it. Puncture protection only time will tell.
