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, a puncture protection fluid seals incisions within a tenth of a second, during the ride Buy Schwalbe Wheels & Tyres from Chain Reaction Cycles, the World’s Largest Online Bike Store.
