Evo SV Schrader Tube

This tube is designed for 20-inch wheels with a tire width between 1.75 and 2.125 inches. Please check the sidewall of your current tire to confirm your specific width falls within this range.

This model uses a standard Schrader valve, which is the same type found on most car tires. It is compatible with standard bicycle pumps and gas station air compressors.

The 48mm valve length is standard for most 20-inch rims. It provides enough clearance to easily attach a pump head without interference from the rim wall.

The 0.9mm wall thickness is a balanced choice for everyday riding. It offers enough durability to handle standard road debris while keeping the tube weight manageable at approximately 159 grams.

No, this is a standard replacement tube and does not feature specialized puncture-resistant liners or thicker rubber compounds. For high-debris areas, you may want to consider adding a tire liner separately.
