STAN'S NOTUBES WHEELS
The Stan's NoTubes Crest XX1 29in Wheelset provides the strength and reliability that long-distance racers and XC riders demand. Even better, it's compatible with SRAM's new XX1 cassettes. So, by using Stan's 3.30 hubs, double-butted spokes, and ZTR Crest rims, this wheelset guarantees both the low rotational weight and tire-enhancing volume that Stan's rims are respected for.
Stan's has been at the forefront of the 29er movement, offering some of the most desirable rims on the market. 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 BST equipped ZTR Crest rim is laced to a Stan's 3.30 hub set. 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 is aluminum and it's also compatible with SRAM XX1 cassettes.
The Stan's NoTubes ZTR Crest 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. It's available with either a 15mm front and 142 x 12mm rear combination or 15mm and 135 x 10mm QR.
Please note that the ZTR Crest 29in Wheelset has a rider weight limit of 190lbs.
