This rear disc brake wheel offers everything discerning cyclists demand: exceptional stability in any wind condition and absolute speed. The revolutionary HyperFoil wavy profile with SawTooth height (53/58 mm) and the HexFin ABLC dimple structure with ImPress printed graphics manage turbulence at its best. The Hookless construction and TSE (Total System Efficiency) technology optimize the transition with the tire, allowing you to ride at lower pressures to drastically reduce rolling resistance and vibration fatigue. The ultra-lightweight premium ZR1 SL hubs, featuring hybrid ceramic bearings and a 6-pawl freewheel system, complete the setup for unparalleled responsiveness and smoothness.
