Inner Tube Protecting, Bicycle Tire Liner - Stop Flats for Mountain and Trail Bikes Using Silver 26 x1.5-1.95” Bike Tires and Tubes with Hard Durometer Center Strip. (1 Liner)

Works great, no flats. Plenty of length. Make sure to look at your tire size and pick the right one.

I haven't had flat tires due to debris on the road since I install them on my bike. Only con I have is that this protective tube can damage the tire if you don't wrap it with something.

While these are not fast to install, they are so far doing the trick. It is not hard just fussy because they curls up and slip around. I was having at least a flat a month from these little thorn buggers from a shrub (in San Diego). I am happy to report, I have run over the thorn things and pulled out of tire without getting a flat. A definite buy......

I put these liners in my tires and rode to work in the bike lane . I live in SF so yes there is glass. On this ride to work, maybe 5 city blocks, I got a flat tire. The liner had been in place for one day. And yes, I did check for glass etc in the tire from the previous flat. There was none to be found. When I took my tire off for repair there was a small price of glass and it went right through the center of that liner like a knife through butter. I feel like I got burned by buying this product.

I wish I had taken a before and after picture, but alas, I did not. We just moved to Kansas and my family was super excited about riding our bikes on the trails around our new home. Within five minutes we discovered that the sandspurs in Kansas are on STEROIDS!!! These are cannondale trail bikes we are talking about and we had three flat tires within 5 minutes.Fast forward, my husband patched the innertubes and put these badboys in and not one flat in hours and hours of riding. My kids are overjoyed!I highly recommend!

a little slippery to install but seems to work well

Much easier to install than I expected. Didn't even need to take the wheel off.The material seems pretty strong, differently much stronger than the tube.

Used this on my 8 yr old grandson's mountain bike . We live in desert community and lots of goathead thorns around. Used these to help combat flat tire issue but ended up still getting flat tires.
