Not all carbon rims are created equal. If your carbon rim is too stiff, you're losing speed and risking tire pinch flats. The Stan’s Crest CB7 rim with RiACT absorbs radial vibrations and damps impacts. It's a difference you can feel in the ride of the bike almost instantly. First introduced with Stan's legendary Valor rim, Stan's impact-absorbing RiACT technology has evolved to be more responsive and even more durable. The Crest CB7's new layup and rim shape allows for 10mm of radial compliance to absorb larger impacts. The new rim also matches the Valor's strength while using less material to save weight. And when it comes to the lateral stiffness needed for steering precision and control, the new CB7 layup delivers. Wider than the original Valor while still optimized for XC tire widths, the Crest CB7 keeps you in control and rolling faster.
Stan’s backs up the technology in every Crest CB7 rim with one of the best warranties available, including lifetime crash replacement. Better by design, the Crest CB7 is the most advanced rim available for creating a lighter, stronger, more reliable, and faster rolling wheelset.

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire bead. UST rims should be paired with UST-specific tires for best results.
