Stans No Tubes Arch CB7 27.5-inch Front Wheel

Imagine the ultimate carbon trail rim. It's wide enough to offer tire stability and control, but narrow enough that your 2.35" tires still corner great. It's light enough to respond instantly from the first pedal stroke, but built with the kind of durability only developed on the Enduro World Series circuit. And when it comes to tubeless set up, it offers the easiest and most trusted system ever made. More than anything it has a clear advantage, a ride quality not found on any other rim and a warranty that backs up all the talk. We created the Arch CB7 to be that ultimate carbon trail rim.

While the competition phones in their carbon rims, we’re busy creating innovative designs that make an actual difference on the trail. Five years of continual development and refinement have led to the Arch CB7'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 Arch CB7 deflects up to 10mm 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 result is a rim that defies pinch flats and rolls faster over every trail.

Arch CB7 rims also feature Stan’s patented Bead Socket Technology, the original tubeless-ready rim design that, combined with our sealant, has become the foundation of all current tubeless-ready systems. The competition can't copy the Arch CB7’s low-profile sidewalls and patented Bead Socket Technology rim design. Our 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.

The Arch CB7 wheelset rolls on updated Neo hubs featuring a Durasync 6-pawl freehub with fast 10-degree engagement, and triple freehub bearings to better distribute axle load. The 100% CNC machined hub shell and smoother-rolling centerless ground axle help ensure long life and reliable performance. Sapim’s Race double-butted spokes are both strong and light. Combined with mechanically locking Sure Lock nipples, these spokes let us build a wheel that’s both lightweight and extremely durable. We’re also strong believers in the benefits of conventional j-bend spokes, which are easy to replace any almost any shop. Arch CB7 wheelsets are available in configurations to fit most axle styles and cassette types, and are available in both Centerlock and 6-bolt models.

The Arch CB7’s performance is backed up by our dedication to quality and taking care of our fellow riders. Register your wheels with us, and your Arch CB7 wheels will be eligible for our 5-year warranty and lifetime crash replacement.

The Arch CB7 is the most advanced trail wheelset from the first name in tubeless performance.

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.
