These are easy to cut, they are much more elastic than I anticipated, but that does make installation easier. I expected these to be firmer plastic that would resist puncture better and flex less. I was able to push a nail through the excess material after trimming it to size, and it didn't take much pressure with a nail that was not particularly sharp or narrow... I got a flat after a week after running over a tack in the road, but I am very skeptical these can offer any protection from regular thorns.

No flats! Rode through iron horse trail path without getting a single flat. Plucked numerous thorns out after ride and have not lost any air pressure.

These are required in my area of the country. Goat Head thorns everywhere, these liners along with heavy duty tubes and green slime help tremendously.

Bandes très dures à installer, fait trembler le vélo. Pour le prix, c'est pas bien pour moi. A éviter je pense

Update..make sure you round the corners on the liners they will pop your innertubes i had 3 flattires in 2 weeks and could not figure out why.i noticed it was always about half way up the side of tube same spot all 3 times.finally i notice it was right where the liners slightly overlapped and the pointy edgehad poked a hole in tube.trimmed the edges and been flat free ever since..Very easy to install and gives you piece of mind.made of very tough material.5 of 5 for me.a few things you need to know.first install with the curl of material down this will keep it fromrolling up as you go around inside of tire.then insert innertube with enough air to hold linerin place (just enough to hold shape) then install on rim and "do not" overlap liner more than an inch or so especially with a ebike (because of high speed) as it will throw off the balance of your tire.found that last one out the hard way.

I can't tell you how it works yet because I haven't really put it to the test but I can tell you some easier ways to put it in first off give it 24 hours completely unwound to relax the curl otherwise you're going to fight it. Secondly I have one of those foam water noodles that fit perfectly inside my tire so for today I put the liner in with the noodles so it formed perfectly to the curve of my tire and that has how it sits until my tube show up. I did not do this on my first attempt on a tire and it took me an hour and a half this new way took me 10 minutes but she does when I put it on the bike again you do not put the water noodle on the bike you just using it to take a place with it too

La verdad que estos protectores vienen bien para los abrojos, aportan resistencia a las cubiertas y la instalación es sencilla, no he notado ninguna diferencia a la hora de rodar pero si es cierto que, en este tiempo no he pinchado.La mejor forma de agradecer el esfuerzo por ayudarte a decidir es dándole a útil en esta reseña, gracias!!

What a waste of $30 some odd dollars because this doesnt work as it's supposed to. I just bought this not too long ago along with brand new very beefy tires for my bike. And already somehow I managed to get another flat tire where a nail happened to pierce through my thick ass tire and through this stuff puncturing the inner tube flattening another tire with not just 1 or 2 holes but so many times that it could not be repaired. Not only that but the way they designed this makes for a very difficult installation and fit inside the tire. I would not recommend that anyone waste their money on this product. I can't even return it cuz i had to cut it down to fit by tire plus I had to use it to find out how terrible it was. So take my word instead of losing out on money and don't buy it. My suggestion would b to spend a little more money and get a better one that actually works.
