Frequently asked questions
Why does the valve shape matter?
The valve needs to suit the wheel and remain accessible for inflation. Compare its shape and direction with your existing tube before ordering.
Is tyre size alone enough to select a tube?
Check both the listed size and the valve arrangement. If you are unsure, send us a photo of the valve and the size marking on your tyre.
