Increased robustnessthe 30mm aluminium rim with fore & pfp technologies makes the crosstrail sl an indestructible trail wheelmore responsive and dynamicthe reduced inertia of the rim combined with infinity hub technology, means instant accelerationultra versatileism4d rim lightning and spoking technology make the crosstrail sl one of the most versatile trail wheels in its classmaxtal aluminium alloylight and strong. Exclusive to mavic, this specific aluminium alloy offers a higher strength to weight ratio than the conventional 6106 alloy.Ism 4d light rim technologyinter spoke milling 4 dimensions ism 4d is an exclusive mavic patented concept. The ism 4d significantly reduces weight and inertia without compromising durability. Quicker accelerations, better handling the right mix to make the most of any ride. The smooth profile also helps reduce aerodynamic drag.Fore tapeless tubeless technologystiffer and stronger. Instead of being drilled, the lower rim bridge is pushed up on the inside, then threaded to enable the spoke nipples to be directly screwed into it, leaving the upper rim bridge intact.Instant drive 360 technologysuper light and efficient. The large contactless rubber seal provides low friction, while a wide array of end caps makes it super versatile.Ust tubeless technologytraction and control. Universal standard for tubeless. Ready to ride tubeless system. The ust concept improves traction, control and comfort whilst reducing inertia and flats.Sup welding techn...
