Air-Liner Gravel puncture insert

With the same impact resistance and tubeless-ready beadlock as mountain bike Air-Liners, the Air-Liner Gravel offers impact resistance, puncture protection, and performance-enhancing stability in narrower tread tires. In hard impacts, the Air-Liner's resistance increases when compressed, preventing rim strikes and punctures, acting as a shock absorber installed in the tire.

In addition to resisting large impacts, the Air-Liner Gravel allows for lower inflation pressure, enabling tires to absorb bumps without transmitting them to the bike. You'll still feel the connection through the contact patch, but with less gravel chatter and less accumulated rider fatigue. The Air-Liner Gravel's profile reinforces the sidewall for increased cornering stability and secures the tire against the rim bead. It also allows the tire tread to remain in contact with the ground, offering responsive traction during climbing and braking. No folding, no pressure loss, no sluggishness, and no punctures.
