This is the Teravail standard butyl inner tube for 27.5 in tires from 2.0 to 2.4 in wide, with a 48 mm Schrader valve.

What it's for

A replacement or spare inner tube for 27.5 in (650b) mountain bike tires. This is the standard weight version, not Teravail's thorn resistant tube.

Compatibility

• Fits: 27.5 in tires from 2.0 to 2.4 in wide
• Rim valve hole: Schrader. This is the wider valve, the same type used on car tires
• Does not fit: rims drilled for Presta valves, which have a smaller hole
• How to check yours: read the size on your tire sidewall and look at your current valve. A Schrader valve is the same width top to bottom with a spring pin in the center
