Sturdy & stable at top speeds, this alloy-built pair comes equipped with a nimble 17mm width & steady 35mm profile to give top-notch balance as you blaze along the asphalt. This design also provides superb radial compliance & strength for a long-lasting & reliable rolling experience. Minimal Weight & Maximum Stiffness The stiffness & handling of each P.E.O-coated, alloy-made wheel are bolstered by inter-spoke R06 milling which maximises the sturdiness of each build without adding unnecessary weight. Both Tri Max models spin on a sealed-cartridge PRA hub, with the rear hub kitted out with a Shimano 10/11-speed compatible freehub to give you that extra boost when climbing or gunning for the finish line. Aero bladed spokes add to the aerodynamic performance of this fast-rolling & robust set of Vision road wheels.
