Accelerate faster, use less energy on climbs.

ISM 4D machined rim is lighter without compromising strength.
24 Zicral spokes with Isopulse lacing (rear) ensures a stiff and responsive ride.

Ride challenging XC terrain with more control.

22mm hookless rim for increased comfort, control and traction.

Better traction, reduced risk of flats with UST tubeless technology.

Simple tubeless tire setup with no tape needed.
Run lower tire pressure for increased control and comfort.

Engineered with a 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".

UST Tubeless Ready

UST Tubeless Ready

Traction, control and lightweight
The UST concept improves traction, control and comfort while reducing inertia and flats.
The 'tubeless ready' construction results in a lighter tyre for improved performance.

ISM 4D

ISM 4D

Inter Spoke Milling 4 Dimensions
An exclusive Mavic patented concept, ISM 4D significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling and more resistance ; the right mix to make the most of any ride. The smooth profile also helps reducing aerodynamic drag

Isopulse

Isopulse

Optimum energy transfer
The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges.

Maxtal

Maxtal

Light and strong
Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.

Fore

Fore

Stiffer and stronger
Instead of being drilled, the lower rim bridge is pushed up on the inside, then threaded to enable the spoke nipples to be directly screwed in it, leaving the upper rim bridge intact.

Zicral

Zicral

Light, stiff and strong
A specific aluminum alloy that provides spokes with higher stiffness-to-weight ratio while being stronger.

QRM+

QRM+

Qualité de Roulements Mavic +
Our most demanding level. Those cartridge bearings are of course double sealed with C3 internal clearance, and toped with a micro-adjustability system.
