Light and fast.

Stan's NoTubes continues to sit atop the rapidly evolving world of tubeless wheels with its advanced rim design and unparalleled tubeless reliability. Not surprisingly, you'll find wheels such as the Arch EX 27.5in Wheelset attached to the frames of almost any type of bike out on the trails. Stan's brings together the light, fast profile of its cross-country specific Crest and the bombproof internal arch design of the gravity-focused Flow to create an all-around wheelset built to tackle a huge variety of trails. All at once lighter, wider, and even more durable than the original Arch, the Arch EX will shred even the most aggressive, technical trails.

This wheelset utilizes Stan's trademark Bead Socket Technology (BST), which features low profile sidewalls that provide a better seat for the tire bead and allow for a heap of benefits compared to standard rims with higher sidewalls. When setup as tubeless, BST provides an exceptional seal while allowing the tire to hold a greater volume of air than standard rims that place the bead 2-4mm below the edge. This interface lets the tire maintain its full shape for a wider, more stable rolling platform than if the same tire were mounted on a standard rim.

Pairing BST features with the ability to run up to 30% lower air pressure in the tubeless system than a standard tube setup results in exceptional tire stability, better handling, solid cornering, and better overall control out on the course. These rims are is also compatible with standard tubes, with the lower sidewall drastically reducing pinch flat risk by reducing the amount of material present for the tube to pinch against. This means less time sitting in the dust wrestling with a flat at the side of the trail and more time shredding your favorite loops.

Stan's laces the Arch EX rims to its all-new Neo hub set featuring smooth-spinning, oversized chrome bearings that glide on a stiff, strong, swaged axle. The Neo holds the bearings at a wider stance for a claimed threefold increase in strength compared to standard hub designs. The Neo boasts 4 precision pawls that simultaneously engage a forged steel 36-tooth ratchet ring for snappy engagement to power down the course. Stan's builds in its new SealLock end caps for easy installation and Slip-Fit axle ends for easy conversion.

The Stan's NoTubes Arch EX 27.5in Wheelset comes complete with Stan's yellow rim tape and valves already installed for tubeless use - just add your favorite tubeless-ready tire, Stan's award-winning sealant, and air to get out and rolling on the trail It's available with a QR/15mm front and 142 x 12mm rear combination with either a Shimano/SRAM or SRAM XD freehub.

Please note that the Arch EX 27.5in Wheelset has a maximum recommended rider weight of 230lbs.
