From gravel grinders to mixed surface road rides, our Allroad Pro Disc delivers everything you need to push the pace when the going gets rough. Lightweight, stiff and responsive, the Allroad Pro Disc features UST Road Tubeless technology with 22mm (internal) wide rims. It’s integrated with our Yksion Allroad UST tubeless tires, and you can choose either 35mm or 40mm width. Our proven UST system lets you run lower tire pressure to improve comfort and handling with no risk of pinch flats. By removing the tubes, we’ve also reduced friction, so you get less rolling resistance and carry more speed on smooth or rough roads. Best of all, the UST system makes it easy to install and remove tires, so you can easily change them according to what terrain you’ll ride. The lightweight rims feature ISM 4D technology (Inter Spoke Milling), which strategically removes material from the rim where it’s not needed but keeps it around the spokes, where tension is applied. This keeps the rim weight low, even with its generous width. This disc-brake specific wheelset features 24 steel spokes front and rear to distribute the brake torque efficiently and evenly. The wheels are compatible with Center Lock rotors. The front hub comes with a 12mm thru-axle and can convert to 15mm or quick release. The rear wheel is 12x142 thru-axle and can also convert to quick release.
