Easton EA90 XC Wheel - 29in $510.00
The Easton EA90 XC 29in Wheel is both lightweight and UST approved — a hard combination to come by. However, UST is reigning favorite for trail-bike applications when durability outweighs crosscountry efficiency.
In this case, however, Easton took the Haven's proven UST technology and dropped nearly 100 grams from the picture. Yet, the EA90 possesses all of the shaping and structural requirements in order to meet the stringent UST standards. 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 per usual, but the nipple pulls double duty. In other words, it's both internally and externally threaded.
When the spokes are drawn into the nipple it's simultaneously threaded into the inner-wall of the rim. This way, 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. Meanwhile, the hubs for the EA90 XC 29in Wheels are machined from aluminum and house standard cartridge bearings for easy serviceability. The front is available in two versions — standard 9x100mm quick-release or a 15mm thru-axle. The rear hub is available as a standard 10x135mm quick-release or a 12mm x 135/142mm.
The Easton EA90 XC Wheel features 19mm internal rim width and a 24mm external rim width. Please note that these wheels are sold individually, and they're compatible with six-bolt rotors.
