Inner tubes are part of the rotating mass, and therefore they should be as lightweight as possible. But they also have to be plenty tough as a flat easily eliminates any gain in time. Onza Tires' inner tubes are available either with a lightweight Presta valve that handles high pressures well or a Schrader valve. The Schrader valve is known from cars and allows you to adjust the tire pressure at any gas station.
Valve type: Schrader-Valve
Presta-Valve
