Developed with top Mavic athletes, the Crossmax SLR UST Mountain Bike Wheel sets a new standard in the Cross-country world: system performance for only 1440g! A new extra-light 19 mm rim reduces inertia to its minimum while the ITS-4 free-wheel provides the fastest engagement. Result: the most dynamic ride ever!

Mavix Mountain Bike Wheel Technologies:

• ISM 3D: Inter Spoke Milling 3 Dimension. ISM3D pushes the envelope of ISM one step further by not only machining the lower bridge of the rim between each spoke holes, but also its sidewalls. Machined sidewalls save even more weight and inertia to boost your acceleration and enhance climbing performance.
• UST: Universal Standard for Tubeless. Traction and control. Ready to ride tubeless system. The UST concept improves traction, control and comfort while reducing inertia and flats. - No tube, no tape, fully sealed rim for convenient handling - Enables to ride at lower tyre pressure - UST rim profile with specific humps to fix securely the tyre beads - Compatible with all types of tyres (UST, Tubeless ready, tubetype).
• ITS-4: Instant Transfer System 4. Using 4 pawls working 2 by 2, the system provides a more dynamic ride, thanks to a very fast engagement. Its versatility makes it compatible with all kind of frame retention system. - Better energy transmission: fast engagement, only 7,5° freeplay between two engaged positions - Stiffer: 17mm monobloc axle - 12mm through axle compatible to fit any kind of frame retention system.
• QRM : Qualité de Roulements Mavic . Our most demanding level. Those cartridge bearings are of course double sealled with C3 internal clearance, and toped with a micro-adjustability system, allowing you to quickly adjust your wheels according to performance goals: precision "free" adjustment for maximum fluidity, or perfect high precision setting for all-weather rides.
• Fore: Only one of the 2 rim wall is "drilled": The rim is 4 times more resistant to fatigue stress 20% increase in the rim rigidity to transfer all of your energy to the ground.
• Isopulse: This spoke lacing design consist in lacing the spokes radially on the drive side and crossed 2 on the non drive side. This lacing pattern brings better wheel stability and a crystal clear transmission of energy thanks to a better spoke tension balance between left and right flanges.
• SUP: Soud� Usin� Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish. A welded and milled rim joint is extremely strong, eliminates shuddering when braking, and offers superior wheel balance.
• Zicral: A highly resistant and lightweight aluminium alloy for spokes.
• Maxtal: Exclusive to Mavic. An aluminium alloy that is 30% more resistant than a 6106 alloy, for lighter and stronger rims.
