IO
First introduced in 1996 and continually improved over the past two decades, the iO RIO has won more Olympic track medals than any other wheel in the world.

The latest generation iO delivers an even greater competitive advantage. It features a wider rim to better integrate the slightly larger tubular tires that are popular with track racers. And each of the five spokes has a NACA profile for further improved aerodynamic drag. The new iO is ready to break its own records.
