The green tubeless inserts for gravel use from Pepis Tire Noodle are specially designed for unpaved roads with gravel and are made from an exclusive technopolymer material. They optimise the functionality of tubeless systems, increase riding precision and protect tyres and rims from impacts. They also allow you to ride with a flat tyre at moderate speed in an emergency. The unique function of Pepi's Tire Noodle generates a foam specially developed for these requirements, the structure of which adapts dimensionally to the air pressure and sits on the rim as secure protection. Smooth running and rolling resistance are positively influenced. In the event of a loss of air pressure or in the event of a flat tyre, the dynamic foam structure in the tyre progressively compensates for the volume and thus enables the tyre to continue riding at a moderate run-flat rate. This safety upgrade is also ideal for everyday use on tours and city bikes.
