All carbon rims are not created equal. 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.
Technology
Stan's No Tubes RiACT Rim Design
Everyone knows carbon fiber can create a stiff wheel. We knew it could do much more. The carbon fiber rims on our CB7 series wheelsets are 30% stiffer laterally than our legendary aluminum rims, but the key to their outstanding ride quality is Radial Impact Absorbing Carbon Technology. Obsessive attention to the shape of the rim and a proprietary carbon fiber lay-up process lets us create carbon rims that absorb radial vibrations and impacts while maintaining lateral stiffness, keeping your wheels driving constantly forward with less energy loss than other carbon rims. Originally developed for or highly successful Valor rim, RiACT offers added strength, less rolling resistance, and the best ride of any carbon rim. On our Podium SRD wheelset, RiACT lets us create a rim that's lighter than the competition while also being stronger. Our carbon rims can deflect 7-10mm without damage or pinch flatting.
Smooth is fast. If there's one thing the overwhelming success of our tubeless technology has demonstrated, that's it. The more forward momentum your wheel and tire can maintain without deflecting off the ground and sending your energy upward and backward, the faster you roll. Our RiACT rims allow the wheel system to absorb more, offering levels of vibration damping and impact absorption never possible before. RiACT lets Stan's Podium SRD, Crest CB7, and Arch CB7 rims and wheelsets roll faster and last longer.
