Maxtal: Exclusive to Mavic. An aluminium alloy that is 30% more resistant than a 6106 alloy, for lighter and stronger rims.
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.
UST: Universal Standard for Tubeless. A better grip for tighter control. No more tube, no more rim tape: sounds too good to be true. The UST concept eliminates heat, friction and guarantees a slow deflating rate if punctured.
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.
