Schwalbe Inner Tubes

Yes, these tubes are designed specifically for 20-inch wheels. They are compatible with tire widths ranging from 1.50 to 2.45 inches, making them a versatile choice for most standard BMX setups.

The standard version (AV7) weighs 145g and is built for maximum durability, while the extra-light version (AV7C) weighs 95g. Choose the extra-light option if you are looking to reduce rotational weight for better acceleration, or the standard version if you prioritize puncture resistance and longevity.

These tubes feature a 40mm valve stem, which is the standard length for most 20-inch BMX rims. It provides enough clearance to easily attach a pump head without being excessively long.

These tubes use a threaded alloy valve stem rather than a standard rubber or smooth metal one. The threading helps secure the tube firmly in the rim hole, preventing movement and reducing stress on the valve base, while the nickel-plated finish resists corrosion over time.

This depends entirely on your current rims. You must match the valve type to the hole drilled in your rim—Schrader valves are wider and typically found on recreational or older BMX bikes, while Presta valves are narrower and common on high-performance setups. Check your existing tube or rim hole to confirm which you need.
