Quick Summary
The Schwalbe AV12 is a Schrader inner tube for 26 x 1 3/8″ wheels. It is a specific tube size and valve combination, so the main buying check is whether it matches your tyre and rim setup.
For this type of product, the important points are size, valve type and exact fit. Confirm the 26 x 1 3/8″ measurement and Schrader valve format before choosing an offer.
What to Compare Before Buying
- Tyre size: This tube is for 26 x 1 3/8″ tyres. Check that this matches the wheel size you need.
- Valve type: It uses a Schrader valve. Compare that with the valve type already used on your wheel or pump setup.
- Exact version: AV12 is part of the product identity, so make sure that is the version you want.
Compatibility, Size and Fit
Inner tubes depend on both wheel size and valve type. This model is specified as 26 x 1 3/8″ with a Schrader valve, so those two details matter most when checking compatibility.
If your tyre size differs, or if you need a different valve format, choose a different tube rather than relying on visual similarity.
Before You Decide
Check the 26 x 1 3/8″ size, confirm the Schrader valve, and make sure AV12 is the version you want before selecting an offer.
