If your carbon rim is too stiff, you’re losing speed and risking tire pinch flats. The 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 our legendary Valor rim, our 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.

The Crest CB7 also features our Bead Socket Technology. Combined with our sealant, Stan’s patented BST rim design has become the foundation of all current tubeless-ready systems. There are many imitations out there these days, but only one true BST tubeless system. The Crest CB7’s tubeless technology means lighter, lower, faster accelerating sidewalls, easier inflation, and reliability that continues to set the benchmark for all tubeless systems.
We back 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.
