Made In Germany
Material
Thermoplastic polyurethanes are recyclable plastics. Since both the inner tube material and the valve are made of TPU, REVOLOOP bicycle inner tubes can be completely recycled. For the sake of the environment.
 
Welding Technology
REVOLOOP's patent-pending welding process makes it possible to weld thermoplastic tubes with large wall thicknesses in such a way that produces an almost-flat scene. Through this technologically sophisticated process, REVOLOOP achieves perfect rolling comfort and the highest possible protection from snakebites and punctures.
 
Valves
Valves developed by REVOLOOP are made of a special, high-strength thermoplastic polyurethane. They combine the highest technical demands with minimum weight and a sophisticated design. The internally welded valve base protects the inner tube from damage caused by sharp edges on the valve bore in the rim and the dreaded valve breakage.
 
AEROCOACH TUBE TEST
Aerocoach tested the rolling resistance performance of the best competing inner tube manufactures and found Revoloop Race Ultra to be one of the top performing inner tubes. Rolling resistances is simply the amount of energy you expend cycling against the equipment you use. A high rolling resistance will require more power to travel at the same speed, whilst low rolling resistance requires less power. And Reveloop Race Ultra requires much less power than most of the competition.
