Check the size printed on your tyre sidewall
How to choose the correct wheel size
To choose the correct replacement wheel, check the size printed on the sidewall of your current tyre. This is the most accurate way to confirm the wheel size you need.
- If your tyre says 26", choose a 26" wheel.
- If your tyre says 27.5", choose a 27.5" wheel.
- If your tyre says 29", choose a 29" wheel.
- If your tyre says 700C, choose a 700C wheel.
Please do not measure the outside diameter of the wheel, as this can give the wrong size.
