Product Details

The Air-Liner is a high-quality polymer insert which provides a tunable system that enhances your ride performances. The Air-Liner allows your tyres to remain stable, grippy, and controlled, even at low pressures.

The Air-Liner is designed using a round cross section, with channels on the top and bottom. The top channel provides room for the tunable air chamber that sits directly beneath the tyre tread. Upon impact, the corner edges of the channel flex first, and progressively build to the thicker portion, as the tyre is compressed. This allows the tread to remain flexible, which increases traction, without sacrificing impact resistance.

The bottom channel allows for easy fine-tuning of the air chamber, and allows for full compatibility of all valve core styles. The round cross-section shape supports a greater contact area within the sidewalls of the tyre casing. Side-to-side tyre stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance.

If your primary needs are to prevent rim strike - use a size smaller than recommended. You will still retain a level of rim protection but will reduce the effectiveness of sidewall stability and run home flat.

• Protection: By cushioning impacts from within the tyre, your expensive rim remains protected, while eliminating flats caused by rim-strike impacts.
• Control: The Air-Liner insert replaces air volume and the reduced air volume allows the tyre to compress and rebound in a more controlled manner compared to standard tubeless systems.
• Performance: Side-to-side tyre stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance. 
• Air-Liner can be used with any type of sealant – preferably without ammonia.
