Teravail Inner Tube

This tube is designed for 18-inch wheels with an ISO diameter of 355. It is compatible with tires ranging from 1.5 to 2.25 inches in width.

A removable Schrader valve core makes maintenance easier, allowing you to inject tire sealant directly into the tube or attach valve extenders if your rim profile requires extra length.

The 0.9mm wall thickness is a deliberate middle ground. It provides enough durability to resist common punctures during daily riding while remaining light enough to avoid adding unnecessary rotational weight to your wheels.

No, this tube uses a Schrader valve, which has a larger diameter than a Presta valve. It will only fit rims specifically drilled for Schrader valves.

This tube is constructed from butyl rubber, a standard material chosen for its excellent air retention and reliability in various riding conditions.
