Compatibility, Size and Fit
Compatibility depends on the wheel and tyre size, not just the brand name. This tube is for 16 x 1 1/8-1.35 inch tyres and uses a Schrader valve. The 40 mm valve length is another point to check if the rim is deeper or if access is tight.
Confirm the tyre marking and valve type on the wheel before choosing the tube. If either the size or valve type differs, a different version should be considered.
Before You Decide

Follow the manufacturer instructions for fitting and inflation.
