Mavic’s Deemax Ultimate wheels are developed with and used by some of the fastest racers on the World Cup circuit, and are among the lightest downhill wheelsets. Their alloy rims were developed using Mavic’s patented ISM weight-reduction technology. This technology creates a central line of standard alloy thickness along the rim. This means the weight of the rest of the rim can be reduced to help acceleration and handling, while it stays just as strong—a key element in downhill. The spokes are double-butted and bladed stainless-steel, with 28 in the front and 32 in the rear to cope with the huge hits that are part of racing the clock downhill. And the ITS-4 freewheel system, with 4 pawls and only 7.5 degrees between engaged positions, reduces the acceleration time out of a corner to get back up to maximum speed.

Deemax Ultimate wheels are compatible with multiple axle standards. The front wheel comes delivered with a 20mm axle, but 9mm and 15mm adapters are available separately, and the downhill-specific rear hub has 150mm spacing and includes adapters to convert it to 157mm. The recognizably-yellow Deemax is available in both 26 and 27.5-inch so you can set up your gravity sled so it's fastest for you.



Inter Spoke Milling:

An exclusive Mavic-patented concept, ISM involves the machining of the lower bridge of the rim between each spoke hole to create a light and rigid rim without reducing durability.

Mavic UST


Universal Standard for Tubeless:

UST delivers a ready-to-ride tubeless system. The UST concept improves traction, control, and comfort while reducing rotating mass and flats.

Mavic ITS-4


Instant energy transmission:

The Instant Drive 360 freewheel system is superlight and engages quickly with only 9 degrees of free movement between engagement points. A large, contactless, rubber seal provides low friction, while a wide array of end caps makes it extra versatile.

Mavic Fore Integrated Aluminum Nipples


Stiffer and stronger:

Instead of being drilled for spoke nipples, the lower rim bridge is pushed up on the inside and threaded to make it possible to directly screw the nipples into the lower rim bridge, eliminating the need to drill the upper rim bridge. Besides improving the nipple-rim interface, this design is ideally suited to tubeless tire setups and helps maintain rim integrity.

Mavic QRM+


Qualité de Roulements Mavic + :

QRM+ is Mavic’s most demanding level of hub and bearing precision. It uses only double-sealed cartridge bearings with C3 internal clearances and features a system for making micro-adjustments to bearing preload.


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.

Mavic SRS (Spoke Retention System)


Spoke Retention System:

Special machining of the hub shell flanges ensures that spoke heads are secure in the hub. The spoke can still move slightly within its slot, so that the wheel maintains resiliency when encountering shock from the road or trail.

Mavic Maxtal Alloy


Lightweight and strong:

Exclusive to Mavic, this specific aluminum alloy offers a higher strength-to-weight ratio than conventional 6106 alloy, allowing greater latitude in design while maintaining high strength and durability standards.

Mavic SUP Welded and Machined


Soudé Usiné Process:

After bending, the rim joint is arc welded. The welded seam is then milled for a smooth finish, resulting in a stronger, smoother, more reliable rim joint.
