Stan's NoTubes has evolved the Arch rim concept several times, with the 6069 aluminum trail rim one of the best available. 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. Now step forward, with the essential Arch, but made in carbon fiber, which has several advantages over aluminum. NoTubes created the Arch CB7 to be the ultimate carbon trail rim, and it is hard to argue against them. It all starts with the thought and engineering behind the Arch CB7, then the use of a very specific carbon construction process that makes this Stans NoTubes Arch CB7 Front Wheel an ideal partner for you and it's rear sibling.

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 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 specifications? How about a 475 gram 29er rim, with a 26mm Internal Rim Width, 32mm External Width and a 19.5mm profile. The result is a strong, large 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.

Arch 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 Arch 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.

The Arch CB7 Front Wheel rolls on the updated NEO hub. The 100% CNC machined hub shell and smoother-rolling center-less ground axle help ensure long life and reliable performance. Widely-spaced steel bearings carry the load stress easily, and the oversized axle offers flexibility of set-up. To connect the Arch CB7 rim and NEO front hub, NoTubes utilizes 28 strong and lightweight Sapim Race 2.0/1.8/2.0 double-butted spokes, laced 3x/3x. Combined with mechanically-locking Sapim Sure Lock nipples, these spokes build wheel that's both lightweight and extremely durable. As always, NoTubes praises the benefits of conventional j-bend spokes, which are easy to replace by almost any bike shop while delivering a forgiving, reliable ride. The Arch CB7 wheels are available in configurations to fit most axle styles and cassette types, and are available in both Centerlock and 6-bolt disc rotor mount models.

While carbon rims 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. Their confidence is backed by a 5-year warranty and lifetime crash replacement program.
