HADRON² Ultimate 500 Disc Brake
Top level aero performance on any course, in any conditions, the HADRON² Ultimate 500 aero wheels are at home speeding down twisty mountain passes, as well as on time trial and triathlon courses. 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. Available only in disc brake version. Full carbon clincher, tubeless ready construction. UCI approved.
