Tubeless Technology Friction between the tyre and tube is now a thing of the past. This crucially reduces the rolling resistance. It is even smaller than with super light competition tyres. With tubeless, you can ride with less air pressure without restrictions to performance! This brings noticeable advantages in comfort, but also significantly more control in critical situations and on poor routes. Tubeless systems provide very high puncture protection. Sudden air loss due to bursting tubes or valves tearing is ruled out. At the same time puncture protection fluid seals incisions within a tenth of a second, during the ride. E-Bike Ready 25 Tyres with this certification feature the best technologies for use with E-Bikes. They meet and excel past the ECE-R75 certification, meaning they are valid for use throughout Europe.
