STAN'S NOTUBES WHEELS
Much like SRAM's XX1, Stan's products caused a stir in competitive racing. And fittingly, the two can now be combined in the form of the Stan's NoTubes ZTR Crest XX1 26in Wheelset.
The no-holds-barred ZTR Podium is just 175g lighter than the Crest Wheelset, yet it's near double the price and has a 170lb rider weight limit. So, if you need a light weight, but want durability, the ZTR Crest is the XC wheel that you're looking for. Using Stan's 3.30 hubs, double butted spokes, and Crest rims, this wheelset provides the low rotational weight and tire-enhancing volume that Stan's rims have become respected for.
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 are laced to Stan's 3.30 hubs. House 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, though, the freehub is aluminum and it's compatible with SRAM XX1 cassettes.
The Stan's NoTubes ZTR Crest 26in 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 front hub is a 15mm QR, and the rear is available as either a 135 standard QR or a 142 x 12mm thru-axle.
Please note that the ZTR Crest 26in Wheelset has a rider weight limit of 190lbs.
