Continental's large range of exclusive race tires is matched by an equally interesting range of tubes. There are normal butyl tubes as well as lightweight and ultra-lightweight tubes.
Multi-size tubes allow greater compatibility with more tire sizes, and fewer tubes. Unitubes are available in both Schrader and Presta valve tubes. Presta valves are available in a variety of lengths.
