Continental Supersonic Presta Valve Tube

The Supersonic is engineered specifically for minimal weight, coming in at just 45 grams. By reducing rotating mass, it helps improve your bike's acceleration and climbing efficiency compared to standard, heavier tubes.

This tube is sized for 650c wheels with a tire width between 18mm and 25mm. Please verify your wheel size and tire width before purchasing, as it will not fit standard 700c road wheels.

A 60mm valve is generally long enough for most low-to-mid profile rims. If you are running deep-section aero wheels, you may need a valve extender or a longer valve stem to ensure you can easily attach your pump.

Because they prioritize weight savings, the rubber is thinner than a standard tube. While they are constructed from high-quality seamless butyl and individually tested, they are more susceptible to punctures and should be treated as a performance-oriented component rather than a heavy-duty daily commuter tube.

While you can use them for daily riding, their primary design intent is for racing or events where every gram counts. If you prioritize puncture protection and longevity for everyday training, a slightly thicker, standard-weight tube might be a more practical choice.
