Product details
Description
The Schwalbe AV12B is a narrow inner tube for compatible 26-inch tyre formats using ETRTO 20/28-590 or 20/28-584. It is designed for tyres from 20 to 28 mm wide and uses a Schrader valve.
Check both parts of the ETRTO code before fitting: the tyre width must be within 20 to 28 mm, and the bead-seat diameter must be 590 or 584 mm. This is a narrow tube, so it should not be used as a substitute for wider 26-inch MTB sizes.
