Tannus Armour has been developed with our patented Aither technology. A multi-cell foam compound that is lightweight, flexible yet incredibly durable. Aither is the culmination of 10 years of Tannus development within the tyre industry Tannus Armour is a foam insert that sits between your inner tube and tyre, providing an additional layer of protection against 4 main types of damage. SHARP OBJECTS | SIDEWALL TEARS | RIM STRIKES | PINCH FLATS VIBRATION DAMPENING The Armour very noticeably absorbs a huge amount of the vibration from the ground (eg. rock strikes) and dissipates the energy evenly in the tube. The result is a much smoother, quieter, more comfortable and compliant ride. LOWER PSI - The Armours near 360° 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 increased grip in wet conditions and loose rock. INCREASED COMFORT - Armour absorbs vibration for a smoother, more comfortable ride. RUN FLAT - If you do 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.
