Accelerate faster and hammer through rough terrain.

Wider 28mm (internal) rim with ISM machining delivers greater control on extreme DH terrain.
Lightweight components, including the ITS-4 freehub and ultralight bladed spokes.

More responsive with a smoother ride.

ISM machining on the rims results in lower inertia for a smoother, lighter feel and quick acceleration.
Ultra-light, bladed and double butted spokes are strong and stiff.
ITS-4 freehub provides instant acceleration out of the corners.

Gives you the same competitive edge as top pro DH riders.

Engineered and developed to meet the standards of World Cup downhill racers.
More World Cup DH wins than any other wheel in the world.

Developed with input from some of the top pro DH racers—including Troy Brosnan, who rode it to a 2017 World Cup win in Andorra—this is one of the lightest downhill wheelsets ever produced. It has been proven over and over again at the top levels of the sport, built with the strength and durability to handle big hits and extreme race conditions. Recognizable with its trademark yellow graphics, the alloy rim is now wider with a 28mm internal width. Constructed using our patented ISM weight reduction technology, the weight of the rim is reduced for better acceleration and handling with zero compromises to rim strength.
The 28 straight-pull steel spokes are double-butted and bladed for the perfect amount of vertical compliance and strength to handle the abuses of DH racing. The ITS-4 freehub, with 4 pawls and only 7.5° between engaged positions, helps you accelerate out of corners faster.
Deemax is compatible with multiple axle standards and comes delivered with a 20mm front thru-axle. The DH-specific rear hub has 157mm spacing and can be easily convert to 150mm with optional adaptors. The Deemax DH is available in 27.5" and ships with UST tubeless valves and accessories.

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.

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

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.

Maxtal

Maxtal

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