Only one of the 2 rim wall is "drilled".
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).
ITS4 - Instant Transfer System 4
4 pawls, working 2 by 2 provide a very fast engagement. 2 large cartridge bearings ensure the smoothest rotation of the hub body.
Maxtal
Exclusive to Mavic. An aluminum alloy that is 30% more resistant than a 6106 alloy, for lighter and stronger rims.
QRM+ - Qualité de Roulements Mavic + (Mavic bearings quality +)
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.
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.
SUP - Soudé Usiné Process
A welded and milled rim joint is extremely strong, eliminates shuddering when braking, and offers superior wheel balance.
UST - Universal Standard for Tubeless
A better grip for tighter control. no more tube, no more rim tape: sounds to good to be true. The UST concept eliminates heat, friction and guarantees a slow deflating rate if punctured.
