Engineered with a wider rim that’s precisely machined for lighter weight and uncompromising strength, the Crossmax Pro elevates the XC experience—whether you’re racing, training or just shredding trails. With an internal width of 22mm and our patented ISM 4D technology, the rim provides a lightweight and dynamic ride quality. The ISM 4D process machines the rim between each spoke hole. This reduces weight without compromising strength, making it easier to climb and accelerate. The Zicral spokes and Isopulse (rear) lacing increase wheel stiffness for sharp, predictable handling. This is a fully tubeless UST system without the use of tape, making it easy to experience the benefits of tubeless, including better traction and fewer punctures. The system is compatible with quick release and 15mm thru-axle on the front, quick release and 12mm thru-axle in the rear. You can choose standard (15x100 and 12x142) or Boost versions in either 27.5" and 29".
