Wheels: The version of the XM 40.4 wheels, for disc brakes, makes them suitable for the hardest runs, with no loss of safety and stability. New flat spokes increase their stiffness and aerodynamic benefits.

Designed for the hardest rides, they are the result of a meticulous production process that consists of lacing and spoke tensioning followed by mechanical truing and dishing, along with lateral and vertical truing carried out on automatic truing machines. This process ensures consistently high product quality and correct spoke tension, which in turn provides excellent performance.



Rims: Alloy, medium-profile, with reinforcement washers.



Hubs: Lightweight alloy, CNC finished, with 6-bolt disc fastening. Precision CNC working ensures perfect alignment of the disc, which provides efficient and safe braking. The high precision bearings are grease-filled for smooth and easy movement and high durability. Axles and freewheel body can be easily and quickly removed and re-installed for maintenance.
