The Crest nameplate has represented and carried the hopes and dreams of many XC racers and those who prefer fast XC trail riding to technical terrain and jumping things. Pedallng is also good for you. First introduced with NoTubes legendary Valor rim, the impact absorbing RiACT carbon technology has evolved to be more responsive and even more durable. The Crest CB7’s 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. 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.

Instead of offering a generic carbon rim option, NoTubes created innovative designs that make an actual difference on the trail. Five years of continual development and refinement led to the Cresf CB 7's RiACT radial impact absorbing technology. Unlike lesser carbon rims that ride stiff and transfer impacts and vibration to the suspension and rider, the special layup and shape of the Crest CB7 deflects radially to soak up speed-robbing impacts, all while being laterally stiffer than just about every other carbon and alloy rim on the planet.

The specifications? How about light? A 325 gram 29er rim, with a 23mm Internal Rim Width, 29.7mm External Width and a 19.3mm profile. The result is a wide, ideal XC footprint rim that defies pinch flats and rolls faster on every trail, while still offering the compliance you desire and the tubeless performance you require. This 29", 32 hole tubeless ready rim is available to build or rebuild your race wheelset. NoTubes has your replacement or custom wheel option needs covered.

Crest CB7 rims feature Stan’s patented Bead Socket Technology, the original tubeless-ready rim design that, combined with their sealant, has become the foundation of all current tubeless-ready systems. The competition can't copy the Crest CB7’s low-profile sidewalls and patented Bead Socket Technology rim design, just try to mimic it's effectiveness. The BST system has become the most copied tubeless rim technology, but nothing comes close to the ease of setup and reliability of a true BST tubeless rim.

While XC carbon rims like the Crest CB7 actually carry more cost upfront, in many ways they are superior to aluminum, with more benefits, and much more durable than you'd expect. Lightweight aluminum rims can't really take much damage. Stan's NoTubes is committed to both their carbon rim engineering and to your well being.
