Choosing the Correct Tube
Check the full size printed on the sidewall of your tyre before ordering. The fractional 27 x 1 1/4 size is different from both 27.5-inch and 700c tyres, so match the complete tyre marking rather than choosing by wheel diameter alone. You should also select the same valve type as your current tube.
