Proven to be the insert of choice by Professional Racers, Red Bull Rampage Athletes, Dirt Jumpers, Enduro Racers, Weekend Warriors, and the like. Tannus Athlete Reece Wallace said "It continually adapts to the trail while you're riding; it's not just a piece of foam that you stick in your tire. So as you move the bike, the insert changes with it."

Tannus has been developing tire technology since 2003 and we are the number 1 brand of airless tire technology in the world. At the heart of Tannus is our patented Aither Technology. Aither is a multi-cell foam compound that forms the structure of the Armour.
