This Hartex Compact inner tube is sized for wider 24-inch tyres from 24x2.25 to 24x2.60, with ETRTO compatibility 57/66-507. It is a butyl tube for compatible mountain bike, junior, cruiser or utility wheels that use a Schrader valve.
Use the ETRTO 57/66-507 marking as the main compatibility check, because 24-inch tyres are made for different rim diameters. Also confirm valve type and clearance with the tyre width fitted to your bike.
