Happy trails.

The Stan’s NoTubes Arch MK3 27.5in Wheelset brings bombproof functionality to technical, aggressive trails. It borrows the light profile of Stan’s XC speed demon Crest and the burly internal arch design of the gravity-focused Flow to step in as a versatile wheelset that’s ready to tackle almost any terrain. Compared to its predecessors, the Arch MK3 clocks in even wider, lighter, and more durable than ever.

The MK3's internal rim width puffs out from the EX's 21mm to a wide 26mm platform built to pair with tire ranging from 2.25 inches to 2.5 inches in width. As expected with any Stan's wheelset, the Arch MK3 incorporates Stan's Bead Socket Technology (BST) and incorporates notably low profile sidewalls that allow the tire bead to seat more effectively, which leads to a heap of benefits compared to standard rims with higher sidewalls. BST results in an exceptional tubeless seal while also allowing the tire to hold greater air volume than standard rims that place the bead 2-4mm below the edge. This interface allows the tire to maintain its full shape for a wider, more stable rolling platform compared to the same tire mounted on a standard rim.

The ability to run up to 30% lower air pressure in the tubeless system than a standard tube setup paired with all those BST features results in exceptional tire stability, better handling, solid cornering, and better overall control out in the dirt. These rims are 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 bunkered down in the dust wrestling with flats and more time shredding your favorite loops.

Stan's new Neo hub set sits at the center of the Arch MK3, featuring oversized, smooth-spinning bearings that glide on a strong, stiff, swaged axle. The Neo holds the bearings at a wider stance for a claimed threefold increase in strength compared to standard hub designs and utilizes four precision pawls that simultaneously engage a forged steel 36-tooth ratchet ring for snappy, ten-degree engagement. 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 MK3 27.5in Wheelset comes packaged 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. It also includes front and rear quick release end caps and skewers. It's available with a 15 x 100mm front axle and a 12 x 142mm rear thru-axle paired with either a Shimano/SRAM or SRAM XD freehub.
