MAVIC Crossmax Disc Boost MTB Rear Wheel 27.5″, SHIMANO HG, 6 Bolt

The Crossmax MTB wheel for racing and trail use has been established for many years and has earned a good reputation among performance-oriented cross-country wheels. Continuous further developments with features and technologies that stem from the wheels of XC pros recommend the system wheel for ambitious rides ranging from cross-country (XC) through to trail. Whether you’re racing or riding demanding trail tours, the Mavic Crossmax rear wheel can handle high demands. The Instant Drive 360 freewheel with two star ratchets impresses with its fast engagement and maximum reliability.

One of the top features of the Crossmax wheel is the stable rim made of Maxtal aluminium. Together with double-butted aero spokes and the lightweight Infinity hub, it ensures optimised lateral stiffness and spoke tension, and thus more dynamics and agility. This combination is specially designed for a wheel set-up with disc brakes.

Mavic’s UST technology has also proven its worth, enabling a particularly user-friendly set-up with tubeless ready tyres and offering all their advantages: ranging from better traction and control through to smoother running and increased puncture resistance. The 28 mm wide Maxtal aluminium rim also makes a contribution to it. It has a hookless rim profile and is optimised for wide tyres and low air pressures. For fast-paced rides with more comfort and full control.

Top technologies:
• UST tubeless technology: The Mavic standard for tubeless tyres not only improves traction, comfort and rolling resistance, but also reduces the risk of tyre defects.

• ID 360 Instant Drive: A lightweight and low-friction Dual Ratchet freewheel system with a fast 9° engagement angle. Thanks to the modular hub design, it offers high compatibility with common axle types and freewheel standards.

• QRM Auto (Qualité de Roulements Mavic Auto): Smooth-running, double-sealed and maintenance-free industrial bearings with high dimensional accuracy and self-adjusting bearing preload.

• SUP (Soudé Usiné Process): Particularly stable, arc-welded rim joint where the weld of the rim joint is perfectly flat milled for a seamless, smooth transition to achieve balanced rotation without brake vibrations.
• Maxtal: Light and strong – this special aluminium alloy offers a better strength-to-weight ratio than conventional 6106 alloys.
