Vittoria Air-Liner Tubeless Insert for Road Bikes - Medium (28mm) Foam-Based Rim Protection, Improved Grip, Puncture Prevention, Run-Flat Safety, Bead Lock Technology, Compatible with Tubeless-Ready 700c Tires

These liners work very well but it is real wrestling match to mount and dismount the tires. I want to like these but the hassle of tire mounting and dismounting is just not worth it to me. I literally had to cut my Continentals to get them off to change tires.

Using a pair of these with Continental GP5000 TL tires I don't notice they're there at all presumably be a use the high pressure in the tire shrinks them down. I had the privilege of using them in expanded form when my front tire hit a sharp rock on a rail bridge. I couldn't find the hole and thought it might be time to call the wife to pick me up. But I rode on it a little and realized it was a bit slow but would definitely get me home. It was a little dodgy on corners or when standing on the pedals but I survived to tell the tale! Back at home with more air available I found the hole plugged it and reinflated with no other problems at all.

I will say these make it EXTREMELY difficult to mount the tire when installing. I have a 28mm tire and would not have been able to do it without the long-handled tire tool I bought for the mountain bike. It's like putting in an inner tube that is already inflated and totally solid. I nearly cried for joy when the last bit of tire popped over the bead.

Using tubeless won't complete prevent you from flatting but putting in these will get you home!;

Proofs in the pudding. The airliners did thier job. I didn't get a flat to experience their abilities but i was able to run much lower pressures. Almost 20psi lower. The ride was smooth and supple even over rough terrain (poor maintained roads) i do like the piece of mind they provide as some of my rides tend to take me on a journey. I still carry a tube and other equipment because as they say "you never know" Fitting the liners to the rim was a bit of work but nothing any cyclist isnt use to especially if you're already running tubeless. Be sure to use the valves that are included as they are designed to work with the liner. A standard valve will only get clogged by the liner as you put air in the tires. Inflation was simple and quick with a standard pump. I have included two of my rides to show their is no difference with them installed. The rides are same roads. One is clockwise (second photo) and the other is counter clockwise (first photo). Hope this helps those out who are interested.
