Choosing the Correct Tube
Check the full size printed on the sidewall of your tyre before ordering. Your tyre should be marked as 26 inch with a width between 1.25 and 1.50 inches. This decimal sizing is different from fractional sizes such as 26 x 1 3/8, so match the complete tyre marking and select the same valve type as your current tube.
Why Choose This Tube?
This is a straightforward replacement tube or spare for bikes using narrower 26-inch tyres. With both Schrader and Presta options available, you can choose the version that fits your rim correctly.
