Stans No Tubes Crest CB7 29-Inch Front Wheel

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.

Like all Stan’s rims, the Crest CB7’s patented Bead Socket Technology sets the standard for easy tubeless setup and reliability. Combined with quality Sapim spokes and nipples, and our updated Neo hub, the Crest CB7 wheelset is a fast, light, and fully serviceable option for XC racing on even the most demanding courses. The Crest CB7 is laced with Sapim Force j-bend spokes in lengths readily available at most shops and features Sapim’s Secure Lock mechanically locking nipples for trouble-free riding. The next generation of Neo hub in the Crest CB7 wheelset includes a Durasync 6-pawl freehub with fast 10-degree engagement, and triple freehub bearings to better distribute axle load.

Like all Stan’s wheelsets, the Crest CB7 is available in multiple configurations to fit just about every axle style and cassette type, and is available in both Centerlock and 6-bolt models. Backed up by a solid 5-year warranty and lifetime crash replacement (with registration), the Crest CB7 wheelset is ready to shave seconds off your lap times.

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.

Stan's No Tubes Neo Hubs

Our original Neo hub has evolved to be stronger and more reliable than ever. The additional stress of larger cassette cogs, more capable bikes, and even more challenging trails led us to create the Neo with Durasync and Neo Ultimate with Speedsync.

From its debut in 2015, the Neo has performed at the highest levels of racing in the most extreme conditions, but constant quality feedback from our teams helped us make it even better. Both Neo and Neo Ultimate now feature triple freehub bearings for increased axle stability to handle even greater vertical and torsional loads. The Neo Ultimate with Speedsync maintains the nearly instant 5-degree engagement of 6 pawls engaging three at a time. The Neo’s Durasync system engages all 6 pawls simultaneously for unrivaled durability.
