Tannus Armour Protective Tyre Insert - 700 x 35-40

Tannus Armour has been developed with Aither technology. A multi-cell foam compound that is lightweight, flexible yet incredibly durable. Either is the culmination of 10 years of Tannus development with the tyre industry Tannus Armour is a foam insert that sits between your inner tube and tyre, providing an additional layer of protection against four main types of damage. Sharp objects, sidewall tears, rim strikes, and pinch flat vibration dampening.

The Armour very noticeably absorbs a considerable amount of the vibration from the ground (e.g. rock strikes) and dissipates the energy evenly in the tube. The result is a much smoother, quieter, more comfortable, and more compliant ride.

Key Features Of The Tannus Armour Protective Tyre Insert

Lower PSI: The Armour's near 360-degree bead-to-bead, protection gives sidewall structure to the tyre, allowing us to ride at much lower pressures without the tyre deforming and becoming slow and difficult to handle.
Puncture Protection: Armour eliminates 90% of all punctures due to its reinforced sidewall and underside protection. Increased Grip: Run at lower pressures for improved grip in wet conditions and loose rock.
Increased Comfort: Armour absorbs vibration for a smoother, more comfortable ride.
Run Flat: If you get a flat tyre you can still ride for a limited period at up to 6mph without damaging your wheel.
Fast Rolling: Engineered to minimise rolling resistance (drag), Tannus Armour provides the ultimate balance of speed and protection.
Easy Installation: Installing the Armour is as quick and easy as installing a regular tyre and is maintenance-free.
