STAN'S NOTUBES WHEELS
While the ZTR Race Gold is Stan's lightest offering, at 230g more, the Crest 29in Wheelset offers the strength and reliability long-distance racers and XC riders demand. Using Stan's 3.30 hubs, double-butted spokes, and Crest rims, this wheelset offers the low rotational weight, and tire-enhancing volume Stan's rims have become 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 has put the little company from NY on the map is it's Bead Socket Technology. In a nut shell, BST rims have a larger inner diameter to seal against tire beads for simpler tubeless inflation, and a lower rim sidewall that reduces stored energy, that allows lower pressures, a more natural, rounder shape, and 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 hubset. The hubs house smooth-spinning chromoly cartridge bearings that ride on a lightweight 7075 alloy axles. The rear hub body features large, 58mm flanges. The driveside houses a hardened 30-point engagement ring, while the non-driveside is machined to reduce weight. The front hub gets a 58mm disc-side hub, with a smaller, 45mm flange on the non-disc side to balance strength and weight.
The freehub is aluminum and it's compatible with Shimano and SRAM cassettes. The Stan's ZTR Crest 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 front hub ships with a 9mm axle, but it can be converted with Stan's 15mm conversion kit. The ZTR Crest 29in Wheelset has a rider weight limit of 190lbs.
