Tannus Armour Tire Liner

works perfectly

I got this because my last inner tubes got punctured by goat heads. Since installing it I have ran over countless more and my tires are still running strong. Definitely a worthwhile improvement.

They are awesome

Local bike shop whined, I went and wrestled one in for them. They did the other not to be showed up. They claimed the Tannus foam insert was too small and the tube would pinch and not hold air for long. So far so good!!
