Tannus Information

At Tannus, we develop advanced anti-puncture technologies that give cyclists and industry partners the confidence to ride without compromise. Our systems are engineered to eliminate flats and reduce maintenance across all riding conditions. We engineer three core product technologies: 🔴 Armour Insert: High-density foam inserts for inner-tube systems that surround the tube to protect tread and sidewalls, reduce pinch flats and absorb impacts, cutting puncture risk by up to 90%. 🟢 Airless Tire: 100% puncture-proof solid bicycle tires made from Tannus’ proprietary multi-cell Aither® 1.0 foam compound, eliminating the need for air pressure while delivering zero maintenance and consistent, long-lasting performance. 🟠 Tubeless Insert: The world’s first modular foam insert system for tubeless setups, engineered to enhance rim protection, improve sidewall stability and deliver controlled run-flat capability without compromising ride feel. Trusted by distributors, bike shops and riders worldwide, Tannus combines proprietary materials, practical engineering and proven real-world performance. Ride Flat Free.
