The Easton Haven 26in Wheel possesses all of the shaping and structural elements required to meet the stringent UST standards. The testing and certification is an expensive process, but Easton decided that the time and monetary commitment would offset the ease of seating beads with a floor pump, and riding without the fear of a burp, or worse, having the tire blow off the rim. In practical terms, you can 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 spoke penetrations in the outer wall of the rim. The straight-pull DT double-butted spokes are placed in the hub in a 3-cross pattern as usual, but the nipple features a fresh design that's compatible with the specific rim -- it's both internally and externally threaded. When the spokes are drawn into the nipple it's simultaneously threading into the inner wall of the rim. And they can be trued exactly like a wheel with standard nipples, only the included valve stem pierce the entire cross-section of the rim. The internal rim width is a sensible 21 mm in order to allow the fitment of 2. 3 - 2. 5in tires for true all-mountain adventures. The Easton Haven hubs run on sealed cartridge bearings and have preload adjusters. This way, you'll have an easy time making sure that your bearings are always perfectly adjusted. The front hub is available as either a 15x100 or 20x100mm option. For the rear, you can choose from a 10x135 QR or a 12x135/142mm axle. The Easton Haven 26in Wheel uses ISO standard 6-bolt mounts for the brake rotors and is available in the colors Brushed Black and Matte Silver. Please note that these wheels are sold individually.
