While Easton is renowned for both aluminum and carbon expertise, its carbon Haven wheels proved its ability to apply the latter to one of the most abusive forms of mountain biking. Its proprietary Armored Ballistic Composite was key to this, and now this composite's strength and durability characteristics have enabled Easton to create one of the lightest, 26-inch UST Disc Wheelsets on the market, the EC90 XC.

Easton pioneered the use of new materials in order to create a cross country wheelset with weights that are more equivalent to lightweight road wheels. In comparison to the alloy EA90 XC wheels, the big difference for the EC90 XC carbon wheels is the new composite rim and the loss of a half pound of rotating mass. This weight reduction amounts to a serious seat-of-the-pants feel. The rims combine carbon fiber with high modulus polyethylene, or HMPE (although you might know it as Spectra) in an epoxy resin system that's been rubberized to further add impact strength. The combination of these materials gives them a superior strength-to-weight ratio.

They also have the UST tubeless logo, which means that they're guaranteed tubeless-compatible, and possess all of the shaping and structural requirements necessary to meet the stringent standards for certification. In practical terms, you're able to seat a UST tire on these wheels by hand and with only a floor pump -- no mess and no fuss. Creating a UST-approved rim is tricky, but Easton found a great way to get around the task of eliminating the spoke penetrations in the outer-wall of the rim.

The straight-pull Sapim double-butted spokes are placed in the hub in a three-cross pattern as usual, but the red anodized alloy nipples are specific for this wheel. They're both internally and externally threaded. So, when the spokes are drawn into the nipples, they're simultaneously threading into the alloy inserts at the inner-wall of the rim. This means that they're able to be trued exactly like a wheel with standard nipples, only the included valve stems pierce the entire cross-section of the rim. The rim features a 19mm internal width in order to allow the fitment of cross country tires up to 2.3in wide.

The EC90 hubs are the same CNC machined units that you'll find on the EA90 XC wheels. The shells are crafted from 7050 T-6 aluminum and have been anodized Red. Sealed cartridge bearings keep the wheels spinning smoothly, even if you ride through sloppy mud. And to save a few grams over a typical steel part, the freehub body is also made from 7050 alloy.

The Easton EC90 XC Disc 26in Wheelset is available with either a standard quick-release or 15mm thru-axle. However, with the appropriate parts from Easton, it's able to be converted either way. The rear hub is convertible and it includes all of the parts that you'll need to run a either a quick-release or 12x135mm and 12x142mm thru-axles.
