Tannus Frequently Asked Questions

TANNUS ARMOUR


Tannus Armour is an insert that sits underneath the tire and over the tube. It offers puncture resistance, comfort, and enhanced riding capabilities.

Each insert is $40. So a set will cost $80.

The insert has a 5,000 mile warranty on them but they can be ridden much longer.

We recommend not running the armour in a tubeless set-up. By using a tube you get improved puncture resistance and the full benefits of a smoother ride and no-hassle that you don’t get with tubeless.

You can find it here: Tannus Tubes or pick them up at your local bike shop.

Tannus Armour is made of a patented material called Aither. It’s a high quality foam-like polymer that offers vibration damping, a smoother ride, and puncture resistance.


One of the great features of the Tannus Armour is that if you get a flat during the ride you can ride a few miles without hurting your rim. However, if you do get a flat please avoid rougher terrain.

The armour will compress some after it’s installed depending on the pressure of the tire. The higher the psi the more condensed the Armour will become. If you wish to keep the Armour as thick as possible then maintain a lower psi. You may also deflate your tire if you’re not going to be riding for a longer period. This allows the Armour to rebound back to its original size.

While they were designed for mountain bikes and gravel bikes, they are great for your commuter and road bikes. They will help with the puncture resistance and overall comfort.
