The Air-Liner MTB is sold individually. You will need to purchase two units if you intend to install them in both your front and rear tires.

Yes, the Air-Liner features a specific bottom channel designed to be compatible with all standard tubeless valve core styles, so you do not need to replace your existing valves.

The polymer material is highly durable and is tested for a projected lifespan of 2,000 hours under normal riding conditions. If you ride in a run-flat scenario, it is rated for one full hour of downhill use.

Yes, the Air-Liner allows you to run lower tire pressures than you might normally use. Because the insert provides extra sidewall support and rim protection, you can experiment with lower pressures to gain more traction and grip without worrying about rim strikes.

Installing tire inserts generally requires a bit more effort than a standard tubeless setup, as you have to seat the insert inside the tire before mounting it to the rim. Once you get the technique down, it becomes much easier, but expect the initial installation to take a little extra time.
