When building your featherweight dream bike, don't forget the tubes! Michelin's Aircomp Ultralight tubes are nearly weightless for minimum rolling resistance and maximum speed.
Schrader valves are identical to those found on car tires. These valves are generally used on hybrid and children's bikes. Presta valves, which are found on most road and off-road bikes, are longer and thinner and feature a threaded tip, which must be opened to inflate (turn counterclockwise).
