Extremely airtight! The Butyl rubber compound prevents pressure loss and fewer occasions to inflate. Extremely reliable! Quality control for safer cycling: Each tube is checked twice at the factory to ensure safer cycling. Having the correct pressure means fewer punctures and reduced rolling resistance.
Schrader valves are normally found on MTB bikes and wider rimmed bike tyres, check your tyre size on the bike and select the correct tube size.
Valve Length: 40mm,
Tyre Size: 28mm - 45mm or 28x1-28x1.75
