Among the finest climbing and breakaway wheels on the market, Mavic's R-SYS aluminum wheelset is ultra light and ultra stiff. A 22/25 front/rear rim depth keeps it light and responsive up front, and stiffer in the rear for better power transfer. Plus, R-SYS lightweight alloy hubs are machined from a single piece of aluminum and feature a slightly beefier skewer for added lateral stiffness. Speaking of stiffness, tubular carbon spokes not only look cool, but reduce flex the point of max efficiency. On the rear driveside, zicral alloy spokes keep the setup true and tough.
