What to Compare Before Buying
- Wheel size: This tube is for 18-inch wheels. Compare that with the wheel size on your bike.
- Tire width: The stated fit range runs from 18 x 2.10 to 18 x 2.50. Check your tire marking against that range.
- Valve type: AV32 mm is listed. Confirm the valve type you need before buying.
- Pack quantity: This is a 2-pack, so it suits buyers who need two tubes or want a spare on hand.
Before You Decide
