Fore
Only one of the 2 rim wall is "drilled".
FTS-X - Force Transfer System X
A fruther improved FTS free wheel system to meet the demand of intensive MTB riding as closely as possible: stregthened pawls, self locking axle end screw to make the freewheel mecanism even more hard wearing and a new seal halving friction torque.
ISM3D - Inter Spoke Milling 3 Dimensions
ISM3D pushes the envelope of ISM one step further by not only machining the lower bridge of the rim between each spoke holes, but also its sidewalls. Machined sidewalls save even more weight and inertia to boost your acceleration and enhance climbing performance.
Isopulse
This spoke lacing design and wheel building brings better wheel stability and a crystal clear transmission of energy thanks to a better spoke tension balance between left and right flanges.
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.
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.
Zicral
A highly resistant and and lightweight aluminum alloy for spokes.
