The REVOLOOP.fat was developed by us as a lightweight tube for fat bikes with jacket widths from 3.8 to 5 inches. With a weight of only about 160 grams in the 26-inch version, it reduces the moving, rotating mass on the wheel by about 250 grams per wheel compared to conventional butyl tubes, making the bike more agile. At the same time, it outperforms standard tubes with increased flank stability and brings you safely through demanding curves. Despite its lightweight, this tube has a high puncture and snakebit resistance. This ensures puncture resistance and safety on the trail. The material formulation specially developed for this tube combines a very high mechanical strength with simultaneous elasticity of the material and thus enables the innovative, specific property profile of this bicycle tube.
