THE TRACK FRONT WHEEL WITH THE MOST OLYMPIC TITLES 
 
IO 2017 
ssc 
Totally reinvented for the 2016 Rio Olympics, the iO is faster than ever - Nuovo 
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!
