Built for Olympic athletes, the new Crossmax SL Ultimate is the most dynamic XC wheelset ever created by Mavic. Lighter, stiffer, faster - it's all about going for gold.
At only 1355 grams, this is the wheel that performance obsessed cross country racers dream of. Developed with input from top pro racers seeking a competitive advantage at World Cups and Olympics, it features an ultralight full carbon 29” rim (340g) for fast acceleration and climbing without compromising stiffness and durability.
Adaptive layup, a specific carbon layup technology enabled Mavic to handcraft these carbon rims with less material between the spokes. The spoke holes are reinforced with strategically positioned carbon layering in a process that minimizes weight without compromising stiffness and strength. A lighter rim means faster acceleration, more efficient climbing, and a more responsive feel on the trail. The external carbon layer features Mavic's new UD² construction for a distinctive look and added durability.
Extensive field testing with Mavic's pro athletes determined that a 25mm inner width was ideal for a quick, precise ride quality and optimized tyre grip on fast racetracks. For more technical trails, some preferred a 30mm width for added control, so Mavic created two options. It's your choice, and you can mix the two if you want. You could choose the Crossmax Ultimate 25 for the rear to boost acceleration and efficiency, and the Crossmax Ultimate 30 for the front to add confidence and control on rugged single-track.
