Information
Made from industry-standard butyl rubber, the Specialized inner tube offers excellent air retention to reduce the need for constant refills while remaining lightweight and thin so as not to hinder progress.
A 40 mm valve stem, longer than usual, is compatible with more rims than the shorter 32 mm valves and provides a better grip for your pump without looking out of place.
- 40 mm valve;
