- Tire size: Match the tube range to your tire size exactly, especially if your tire sits at the edge of the stated range.
- Valve type: Check that AV32mm matches the valve opening and wheel setup on your bike.
- Pack quantity: This is a 2-pack, which matters if you only need one replacement tube.
- Bike fit: The tubes are described for several bicycle types, so confirm the fit for your specific wheel and tire combination.
Before You Decide
Confirm the tire size on your bike, the AV32mm valve requirement, and the 2-pack quantity before choosing an offer. If your wheel setup calls for a different valve type or a different 20 inch size range, select a different tube.
