SpinSkins Race tire liners are a high-performance tire liner designed to prevent flat tires. They are lighter and more puncture resistant than other tire liners. SpinSkins outstanding toughness is derived from their patented weaving technology that produces the tightest weave achieved with high-strength fibers. This construction is even capable of crushing the toughest thorns from cactus, goathead, hawthorn, and mesquite.
These things work great! They are a little tricky to install, but once properly installed, you can roll over just about anything!!
I had been getting one or two flats almost every ride from goat heads. I put these in and got four flats on my next ride.you mine as well put a twenty dollar bill in each tire. It would do just as much good
