Not just any tube. As the mixture of the rubber is extrem important for the quality of your tube, we contacted Sir Mixalot to create our special Ruff Tube. And Bravo there it was - Reliable and Airtight.
The Ruff Tube is built for perfect rides on your custom bike and fits your tire as good as any negligee.
