'Bike Tire Liner, Inner Tube Bicycle Flat Protector Compatible with 12'' 16'' 18'' 20'' 24'' 26'' 27.5'' 29'''

My mountain e-bike is getting all new tyres and tubes and this was the last thing I needed.Made from ‎durable polyurethane and at 29 inches in length they should fit any tyre you have except for fat tyres.I'm riding 27.5 x 2.1, so these will fit perfectly with just a small trim in length.These liners should be 100 times better than what I used before because these liners have a ribbed texture that will help it from creeping inside the tyre.Inner tubes in general lose tire pressure over time and there's always need to top up the tyre pressure.When the tyre pressure dips below ideal range the liner inside the tyre can slip and creep a tiny bit. My old liner was totally smooth both sides and it did creep.Hopefully this liner will be better, I'm sure it will be better.Moreover, this liner is a tad thicker than my old one which means it should be more durable.Installation tip: I use a small piece of double sided tape, preferably double sided carpet tape, about 1 inch x 1 inch, and tape the starting point of the liner so it seats properly in the middle of the inside tyre. That way there's no shifting of the liner as you're putting the inner tube inside the tyre.

I was skeptical, until they arrived. They are thick and stronger than you might think. They were tested in a huge patch of goat heads. After an hour of picking thorns out my tires, no leaks. Not even one. They are a challenge to install. Be ready for that. But they are a great buy. Get you some

se me hizo algo delgado pero yo creo que si funciona

I use this shield with slime; it's perfect. I've had hard times without it.

Me creía que me iba a costar más trabajo ponerlo y fue falil.
