• The Vittoria Air-Liner is a tire insert, designed for use in tubeless tires.
• Air-Liner increases control, durability, performance, and protection of both tire and wheel.
• Compatible with any wheel size (up to 29”), any tubeless valve, and tire widths from 1.9-4.0”.
• More grip, in both climbing and descent
• Enhanced rim protection
• Allows for lower tire pressures
• Prevents bead burping effect
• Absorbs high-frequence vibrations. Comfort increased.
• Allows for tires with lighter casing
• Ride home with dead flat.

The Air-Liner is a high-quality polymer insert, which replaces a portion of the air volume in the tire. This trait, combined with the shape, provides a tunable system that enhances your ride performances. The Air-Liner destroys the traditional compromise of stability vs. grip, and allows your tires 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 tire tread. Upon impact, the corner edges of the channel flex first, and progressively build to the thicker portion, as the tire 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 mimics the natural shape of the tire, and supports a greater contact area within the sidewalls of the tire casing. Side-to-side tire stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance.• Protection: Both wheel and tire are protected by the Air-Liner insert. By cushioning impacts from within the tire, your expensive rim remains protected, while eliminating flats caused by rim-strike impacts. • Control: The Air-Liner insert replaces air volume in the tire. The reduced air volume allows the tire to compress and rebound in a more controlled manner compared to standard tubeless systems. • Performance: Side-to-side tire stability is increased, yet the tread remains soft and grippy. This improves cornering, climbing, and braking performance. • Durability: This highly durable polymer material has been tested to a projected life of 2000 hours under normal riding, or 1 full hour of run-flat downhill use under a typical rider.The Air-Liner is available in 3 sizes in New Zealand, and is compatible with all makes and models of tires. M = 2.25’’ – 2.5’’ All MTN / EnduroL = 2.5’’ – 2.70’’ Enduro / PlusXL = 2.70’’ – 4.00’’ Plus / Fat

Gravel

Rim and tire protection for your TLR Gravel bike.

For tyre size from 31mm to 40mm - Rim internal widhth up to 25mm max.

Works with 650b or 700c wheels - simply cut to length.

Protection: The Air-Liner GRAVEL insert absorbs impacts, preventing the risk of pinch-flats, while simultaneously reducing tire burping at the bead, since the Gravel specific shape produces a beadlockfor your tire.

Control: Air-Liner GRAVEL replaces a portion of air volume inside the tire, allowing for lower pressure, and a more controlled deformation. This allows for better tire grip, and significantly reduced handlebar vibration when compared to a standard tubeless-ready set-up.

Performance: Air-Liner GRAVEL increases lateral stability without compromising grip and adherence. This allows for better cornering, climbing and braking performance.

Durability: The polymeric material of Air-Liner GRAVEL is extremely durable. In normal conditions, it lasts up to 2000 hours of use; or 1 hour completely run-flat.

Air-Liner GRAVEL is re-usable and very easy to install – as easy as mounting an inner tube inside your tire – and it is compatible with tubeless-ready tires only and with 3-way valves (in the packaging, a
5-way valves is provided for ultimate airflow). The insert can be used with sealant – preferably without ammonia.

Air-Liner GRAVEL is compatible with wheels of any diameter up to 29” (700c), and up to 25mm internal rim width. For ensuring the best fitment with any wheel, the insert has been designed to be cut according to the desired wheel diameter. Air-Liner GRAVEL is available in one size only.
