Mavic Deemax Ultimate UST Wheelset Technologies:

  • ISM: Inter Spoke Milling Lighter rim and equal rigidity is the magic equation to reduce inertia and to free extra power for climbing. A Mavic patented exclusive concept (US 6 402 256).
  • 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.
  • Maxtal: Exclusive to Mavic. An aluminum alloy that is 30% more resistant than a 6106 alloy, for lighter and stronger rims.
  • SRS: Spoke Retention System. The hub shell slots special machining makes sure that the spoke head is emprisonned and will not pop out of the hub. The spoke still can travel in the slot, in order to let the wheel absorb some of the terrain obstacles: No spoke ejection, even under very hard frontal hits The wheel stays vertically compliant.
  • SUP: Soudé Usiné 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.

Rated 4.8 out of 5 by 4 reviewers.
Rated 5 out of 5 by Superb! I'm using a set of these (20mm & 12/150) on an Intense 951, perfect match for the bike, they look awesome! These wheels are an engineering masterpiece but built to take punishment too. They impress straight out of the box - bladed spokes which lock into the rim are pure class and the rear hub engages / clicks like a Swiss watch. They still spin 100% true and I expect no different 12 months down the trail. Ok they're not exactly cheap! but you really get what you pay for. 100% recommended ! 04 October 2013

Rated 4 out of 5 by Esteticamente, forse le ruote da Dh più belle e leggere sul mercato,peccato il prezzo elevato!! Ricordati, per chi le possiede, di tenere d'occhio la chiusura dei cuscinetti sulla ruota posteriore con l'apposita chiave data in dotazione! GOOD RIDE!!!!!!! 21 June 2012

It's possible to add a tube and use them with a normal tyre or they can be used tubeless with UST-specific tyres. You have the option.
