Low inertia Inter Spoke Milling. Lighter rim and equal rigidity is the magic equation to reduce inertia and to free extra power for climbing. Light and strong Exclusive to Mavic, this specific aluminium alloy offers a higher weight to strength ratio than conventional 6106 alloy for the rims. Usine Brut Control - The braking surfaces are precisely CNC machined. The spokes are laced radially on the drive side and crossed 2 on the non drive side to maximise drive side dish, thus providing a better spoke tension balance between left and right flanges.
