New Michelin bike inner tube squeezes punctures closed
The uniquely shaped and textured Michelin Protek Max bicycle inner tube is said to compress punctures closed, instead of blowing them open
Article Summary
Bicycle inner tubes that contain a small-puncture-sealing slimy liquid may not be a new development in and of themselves, but Michelin has released a product that takes the concept a step further.
