Key Details
| Detail | Product information and buyer relevance |
|---|---|
| Tube size | 20 inches for tires 3.5 to 4.0 inches wide. Match both measurements to the tire marking. |
| Valve | 32 mm Schrader. Check that the bicycle uses a Schrader valve and that the stem length suits its rim. |
| Material | Butyl rubber. |
| Pack contents | Two inner tubes and two tire levers. |
What to Compare Before Buying
- Check the tire’s marked diameter and width. A 20-inch diameter alone does not confirm that a tube in this width range is suitable.
- Confirm the valve type and 32 mm stem length against the bicycle’s rim and existing tube.
What Is Included
The pack contains two tubes and two tire levers. The levers are intended to help remove and install a tire during tube replacement; no other repair accessories are specified.
Before You Decide
Match the complete tire size, confirm Schrader valve compatibility and stem length, and check that the two-tube pack suits your needs. Avoid sharp tools around the tube during handling.
