With the aim of making the carbon rim lighter and stronger than the aluminum rims from Stan's NoTubes, the structure of the "Valor" carbon rim was developed to absorb radial vibrations. This makes the "ZTR Valor" the most modern wheelset NoTubes has ever made and not as hard to ride as carbon rims from other manufacturers. The "ZTR Valor" uses a construction that is both elastic and strong. The NoTubes carbon rim was not only designed to be stronger and lighter than their aluminum rims, but also to get better riding characteristics on the trail.

The wheelset will be available in 26, 27.5 and 29-inch versions. There are also several axle options and an 11-speed XD version. The hub is based on the "3.30 Disc Ti". The rim is held on the hub with 28 spokes at the rear and 24 spokes at the front. Compared to the tried-and-tested "Arch EX" rim, the "Valor" is 60% stiffer and also has a wider rim bed than the "Arch" and "Crest" rims.

The weight of the wheelset, which is designed for cross-country and marathon racing, is also interesting. The 27.5-inch wheelset, with a 15 millimeter thru-axle at the front and an XD hub with a 12 millimeter thru-axle at the rear, weighs only 1,200 grams. The 29-inch wheelset is barely heavier at 1,230 grams.

The prices have not yet been set. The "ZTR Valor" wheelset should be available in Switzerland in spring 2014.
