Focus: The ultimate "set-and-forget" protection for all bikers! Product Description: Stop letting flat tires ruin your ride. Tannus Armour Tire Inserts provide the ultimate 360Adeg puncture protection for cyclists who value reliability above all else. Engineered with patented Aither multi-cell foam technology, this insert wraps around your inner tube, offering a massive 15mm of protection under the tread and 2mm of sidewall support. Whether you&';re navigating glass-strewn city streets on an electric bike or tackling thorny trails on a mountain bike, Tannus Armour acts as a shield against sharp objects and pinch flats. Beyond protection, the foam compound dampens vibrations for a smoother, "pillow-like" ride and allows you to run lower PSI for increased traction and control. Even in the event of a total air loss, the run-flat capability ensures you can limp home without damaging your rims. Puncture Proof: Reduces flat tire risk by 90% against thorns, glass, and debris. E-Bike Ready: Optimized to handle the higher speeds and torque of heavy e-bikes. Run-Flat Technology: Ride up to 10 miles at low speeds on a flat tire to get home safely.
