Key technology

LightnessMaxtal aluminum alloy
Light and strong Exclusive to Mavic, this specific aluminum alloy offers a higher strength to weight ratio than conventional 6106 alloy.
LightnessISM 4D light rim technology
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
Efficiency RigidityUST tubeless technology
Traction and control Universal Standard for Tubeless. Ready to ride tubeless system. The UST concept improves traction, control and comfort while reducing inertia and flats.
Safety ReliabilityUB Control brake track technology
Usiné Brut Control The braking surfaces are precisely CNC machined.
Safety ReliabilitySUP welding technology
Stronger and smoother joint Soudé Usiné Process. After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish.
