What to Compare Before Buying
- Wheel size: Check that your wheel is 27.5″ or 650B.
- Tyre width: Compare your tyre width with the stated 1.75″ to 2.5″ range.
- Valve type: Make sure your rim and pump setup suit a Presta valve.
- Pack quantity: This is a pair, so confirm you want 2 tubes rather than a single spare.
