Their lightweight, stiff Maxtal aluminum rims feature Mavic's ISM technology (Inter Spoke Milling) for even more gram savings so you can fly up steep, technical climbs. For point-and-shoot stiffness, the SLRs are laced up with Mavic's Zicral spokes, while their sealed-bearing QRM+ hubs spin practically friction-free no matter how sloppy it gets out there.
