The Vittoria Competition butyl tubes are extruded with the latest available technology to ensure a uniform wall thinness and relatively high elasticity for butyl, while reducing weight. Air pressure retention has been improved. The valve stem has a reinforced lip around the stem base to reduce the risk of accidental puncture or pull through when disengaging a pump head. The Competition butyl road tube uses a classic threaded valve stem with removable Presta valve core, and includes a lock washer and cap.

Make sure to choose the correct valve length and diameter tube to meet your needs. A simple way to determine your valve length is to measure your rim depth and add 15-25 millimeters and select the closest match length. The diameter range and volume of the tube should match the diameter and volume of your tire.
