Continental ContiTech Tube

This tube is specifically designed for 20-inch wheels with a tire width between 1-1/8 and 1-1/4 inches. Please check the sidewall of your current tire to ensure your specific size falls within this range before purchasing.

This tube is equipped with a 42mm Presta valve. Presta valves are the thinner, threaded valves typically found on performance and road-style bicycles, which require a compatible pump head.

The seamless butyl rubber construction eliminates potential weak points found in tubes with molded seams. This design significantly reduces the risk of splitting or leaking at the seam, leading to a more reliable and durable tube over time.

Yes, every Continental ContiTech tube undergoes individual testing at the factory. This quality control process ensures that each tube is airtight and free from manufacturing defects before it reaches you.

While you can technically install a Presta valve tube in a rim drilled for a Schrader valve, it is not recommended without an adapter. The Presta valve is narrower and can move around in the larger hole, potentially causing the valve stem to tear or fail under pressure.
