HADRON² Classic 500 Disc Brake
The HADRON² Classic 500 offers top-level aero performance, whether on twisty mountain passes, flat time trial courses or everything in-between at an affordable price. Their shallow rim profiles are designed to maximise handling and aero stability in high wind conditions by minimising the sensitivity to gusty crosswinds. The 20mm inner rim width is optimum for minimum rolling resistance with 25mm and 28mm tyres and remains compatible with even wider tyres. Full carbon clincher, tubeless ready construction. UCI approved. Includes lifetime warranty for material and workmanship defects and a Fair-Share-Policy for any other riding damage.
