A replacement bicycle valve stem.

What it's for

A separate valve stem is used in a tubeless wheel, where there is no inner tube to carry the valve. It seals against the rim's valve hole and lets you inflate the tire.

Compatibility

• How to check yours: confirm the valve type your rim is drilled for and that the stem is long enough to clear your rim depth. Bring the wheel in if you are not sure.

Setup and installation

• OMG's bike shop can install the valve and set up the tire.
