    Totally reinvented for the 2016 Rio Olympics, the iO is faster than ever

    This wheel has won more medals than any other wheel on any racetrack in the world. At London the iO won 90% of the medals (27) in the velodrome. And the new generation iO RIO delivers the marginal gains needed to win even more. Completely redesigned, it features a wider rim to better integrate the slightly larger tubular tires now popular with the world's best athletes. Each of the five spokes also now adopts a NACA profile for further improved aerodynamic drag. It’s ready to break its own records!
