Thorn Buster, Inner Tube Protecting, Bicycle Tire Liners Pair - Stop Flats for Road Sport and Endurance Bikes Using red 27 x 1 1/4" - 1 1/8” / 700c x 28-35 Bike Tires and Tubes (2 Liners)

I bought these 6 months ago now, and the only flat that I had was found to be a pinch flat on the inner wheel side of the tube. Goat head thorns are bad around me especially during tumble weed season. I ride almost every day. I also use tires that are resistant to punctures, and back them up with "Slime" tubes. This combo has gotten me home every time! The pinch flat was discovered the next day before another ride.Thorn Buster's liners are a must. They are light, and easy to install. Easy Peazy! When I bought a new bike last year, within a week, I came home with 2 flats before I did anything with my tires and tubes. About 2 months ago, I found a thorn stuck into my tire tread before a ride. The Thorn Buster did its job! There was no leak.I would buy these again, over and over...

I was getting many thorns in my tires. This really significantly reduced the time I spend on the road repairing tires.However, just yesterday, my back tire got a thorn in the side (not exactly sure that happened).This product works as expected -- I just need to not get thorns on the side of my tires. :-)

This product immediately caused a flat. Probably due to user error during installation. Very difficult to install neatly. Been running without them for hundreds of miles and no issues.

Quality Product, relatively easy to install, and it's been doing it's job.

Like several other buyers already complained, this liner completely shredded itself after only three years of very light use (see the attached picture). It thereby likely sliced my inner tube. My previous liner had lasted for 35 years before it disintegrated!

I would get a tire puncture on the rear tire each time I took the bike on the road. After installing this liner I have taken the bike out twice on asphalt and dirt. No flats so far. Just what I needed to safe me the expense and hassle of multiple tube change.

I feel a lot more confident when I unintentionally ride over glass, I not longer have to worry about my inner tubes being puntured.

One flat with goat head, larger objects it works very good.
