Michelin’s developed new bike inner tube tech to cut down on the devastation a puncture brings when you’re out riding. The Protek Max tubes contain a sealant which sees punctures compress and then self-seal, meaning you can hop back on that bike instantly.
The surface of the inner tube is actually visibly different to traditional tubes, with little raised bumps that stop them from twisting. They also aid the self-healing process, by making the rubber compress (as opposed to expanding.) The air pressure theoretically should close the hole, with the inbuilt sealant then locking them up.
On sale now, they cost around $US9 in two different sizes. [BikeRadar via GizMag]
