SPRE Vit Air Liner Light Grav

Superlight performance, protection, and run-flat capability for your tubeless Gravel race tires.

Whether you’re a gravel enthusiast, endurance racer, or bikepacking adventurer, the Air-Liner Light Gravel ensures a more comfortable and reliable riding experience. Designed specifically for gravel tubeless tires, this innovative insert revolutionizes the wheel-tire system for gravel applications. Building on the triumph of the recently launched Air-Liner Light XC insert and the proven expertise of the previous Air-Liner Gravel insert, Vittoria has crafted a groundbreaking new generation of gravel inserts that redefine performance, offering benefits that extend well beyond mere puncture protection.

The ultralight construction also limits rotational mass above the bead, and it reinforces the sidewall while letting the tread ride on air. The contact patch stays fluid on terrain and punchy while pedaling, but the tire does not flop or fold under lateral loads or while cornering. This insert prevents punctures, progressively ramping up under compression to eliminate rim strikes and snake bites when you over-send a line or catch a square edge. It expands after a flat and can be run flat.

Features:

• Increase comfort for long days on the bike
• More grip
• Save your rims from impacts
• Reduce the risk of snake bite punctures
• Increase cornering support
