XX1 compatibility with NoTubes speed.

SRAM's XX1 drivetrain is a game changer. It features a simplified one-by setup that consists of a cassette with a massive gear spread. However, this innovation requires a very specific freehub design that's now found here on the race-ready Stan's NoTubes ZTR Arch EX XX1 29in Wheelset.

From its inception, Stan's has been at the forefront of the 29er movement. The reason is simple, with a low-weight and tire-enhancing properties, Stan's wheels provide the confidence needed for race day. Aside from Stan's award winning sealant, what put the little company from New York on the map was its Bead Socket Technology (BST). In a nutshell, BST rims have a large inner diameter to seal against tire beads. Accordingly, this aids in a simplified tubeless inflation. You'll also find that the low rim sidewall reduces stored energy, allowing the low tire pressures that create a natural, round shape at an increased volume.

In fact, Stan's BST rims allow riders to run approximately 30% less pressure than conventional rims. This directly translates into enhanced traction when climbing, descending, and turning -- along with a more supple ride and lower rolling resistance. With these virtues, it's clear to see why Stan's rims are almost omnipresent on race courses and trail heads alike.

The ZTR Arch EX used on this wheel build is an update on the original Arch. It's intended for aggressive riding and heavier riders, where the Crest and Flow are intended for XC and gravity respectively. The Arch EX drops 50g from the Arch, and does so with added width and strength.

The wider, tougher, and lighter Arch EX rims are mated with Stan's 3.30 hubs. Housed within the hubs are smooth-spinning chromoly cartridge bearings that ride on lightweight 7075 alloy axles. The rear hub body features large, 58mm flanges, while the driveside houses a hardened, 30-point engagement ring. At the non-driveside, Stan's machined the hub in order to reduce weight. At the front, we find a 58mm disc-side hub, with a smaller, 45mm flange on the non-disc side in order to balance strength and weight. Even better, the freehub body is aluminum and it's compatible with SRAM XX1 cassettes.

The Stan's NoTubes ZTR Arch EX XX1 29in Wheelset is laced with 2.0/1.7/2.0 butted steel spokes and alloy nipples. It comes with Stan's rim tape and valve stems installed for instant use -- just add tires, sealant, and air. The Hubs are available in either a 15mm front and 142 x 12mm thru-axle rear configuration or 15mm front and 135 x 10mm QR rear.

Please note that Stan's does not recommend this wheelset for riders exceeding 230 pounds.
