FAQ

Q: What is the difference between Presta and Schrader valves? A: Presta valves are narrower (typically 6mm) and commonly used on road bikes and higher-pressure applications, while Schrader valves are wider (8mm) and the same type used on car tyres. Make sure to choose the valve type that matches your wheel rims.

Q: What is vulcanisation and why is it important? A: Vulcanisation is a heat-cured rubber cross-linking process discovered by Charles Goodyear that makes the rubber stronger, more elastic, and resistant to temperature changes. This process ensures Continental tubes maintain their integrity and performance over time.

Q: How do I know which size tube I need? A: Check your tyre sidewall for the size markings (e.g., 700c, 26", 650) and width range (e.g., 20-25c, 28-32c). Choose a tube that matches both your wheel diameter and falls within the tyre width range.

Q: Why is talc powder applied to the tubes? A: Talc dust is applied during packaging to prevent the rubber from sticking to itself during storage and transport. This makes the tube easier to install and helps maintain its shape.

Q: How are Continental tubes tested for quality? A: Every Continental tube undergoes rigorous inflation testing to check for leaks and ensure consistent wall thickness throughout. This quality control process ensures reliable performance and durability.
