German technical polyurethane

Using German technology, get rid of the traditional heavy Kevelar, switch to the
new lightweight polyurethane polymer composite material, better elasticity and ductility, thus better stinger resistance.

TESTstab test

Using the Disc screw tool and the sharp quincunx tool to test, With a lot of force, of course, this is 100% penetrating,
But we want to show that our puncture pad is more than threefold as malleable as the regular product without puncture. This will maximize the protection of your tires.

Installation tutorial

1 First give the inner tube a small amount of air, so that the inner tube can withstand the puncture-proof tire pad,  but does not affect the installation.

2 Place the inner tube flat inside the outer tube.

3 Remove the puncture pad, put it inside the inner tube, and slowly extend it forward,

Since the inner tube has a small amount of air in advance, it can withstand the puncture-resistant tire pad, so that the puncture-resistant tire pad is located exactly in the middle of the inner tube.

4 When installing the tire pad, pay attention to the position of the tire pad so that it is just in the middle of the inner tube. If it shifts, please adjust it in time.

5 Let's reduce the excess at the interface, you can keep it a bit longer, and this position can overlap.
