Alpinist CL II
Lightest in the Class
Mass Is the Enemy of Performance
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.
Low Mass. Massive Durability.
The Alpinist CL II utilizes the same rim as the Alpinist CLX II. 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.
Systems Approach
It takes more than a lightweight rim to deliver the incredible reactivity and handling of the tubeless Alpinist CL II. The wheelset is designed as a system with our engineers controlling and testing every part of that system—hubs, rims, spokes, lacing. The result is a 1375-gram tubeless wheelset with an otherworldly ride quality designed for real-world road pressures.
Hooked on Tubeless
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 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. This is tubeless done right.
Reliability Means Performance
The Alpinist CL utilizes components curated to make to keep you rolling and rolling fast. The DT Swiss 350 hubs, featuring their Star Ratchet drive system is 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.

How we made it
Made in racing
“We want the fastest option, and tires are faster than tubulars. This is a fact. Well, the next step we know it's tubeless. We raced tubeless already. We won with tubeless already.” - Ricardo Scheidecker, Technical and Development Director, Quick-Step Alpha Vinyl
Testing Tubeless
We are always chasing the fastest way from A to B, regardless of what that technology is. For the last two seasons, our tube-type wheels won 155 races on the World Tour—more than any other wheels. But we knew tubeless had the potential to make these wheels even faster. It took two years and the biggest development and testing program ever undertaken by Roval, but we can now say tubeless is truly ready.
