Bike Tyre Liner Puncture Resistance

SpinSkins tyre liners exceed the puncture resistance protection provided by other tyre liners. Our SpinSkins Race model offers over twice the puncture resistance! Lab evaluations of puncture resistance levels are performed on the Instron Corp. Series IX Automated Materials Testing System per modified European Standard EN344. This testing equipment measures the pressure in pounds of force that it takes for a .05-inch needle traveling at a constant, automated rate of .395 inches per minute to puncture a material to a depth of .045 inches. The needle used in this testing procedure is as sharp as any thorn found in nature.

Lightest Bike Tyre Liner

Whether you are on a mountain, road, or touring bike, your total combined wheel weight is critical to minimize overall bike weight. The centrifugal forces produced by the revolution of the wheels pushes the tyre’s weight outward, which increases the amount of effort required to move the bike. This can create an obvious negative impact on overall cycling performance. SpinSkins add minimal weight and offer the most protection from punctures. Our SpinSkins Race mountain bike tyre liners weigh a mere 34 grams and SpinSkins Duro mountain bike tyre liners weigh only 41 grams. Other flat protection systems are as much as seven times heavier than SpinSkins bike tyre liners

Minimal Bike Tyre Liner Thickness

The thickness of your bike tyre liners is an important consideration for overall performance. Thick tyre liners create a significant overlap that produces an annoying thump that can be felt with every revolution. As tyre pressure increases, these overlaps become even more pronounced. SpinSkins tyre liners are only .022 and .029 inches thick, which is equivalent to the thickness of only three sheets of paper. This thin profile results in a minimal amount of overlap, making properly installed SpinSkins tyre liners unnoticeable to the cyclist at pressures up to 140 psi.
