REVOLOOP REVO.FAT Fatbike Tube - 26"x3.8-5.05 - SV 40mm

REVOLOOP REVO.FAT Fatbike Tube - 26"x3.8-5.05 - SV 40mm

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 convinces by an increased flank stability and brings you safely through demanding curves. Despite its lightweight, this tube has 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.

The valve is made of particularly impact- and break-resistant thermoplastic material and is ahead of its time. Minimum weight coupled with maximum performance.  A specially designed valve foot prevents damage to the hose due to sharp edges on the valve bore. The tough plastic minimizes valve breakage during the toughest trails with low air pressure.


  • ETRTO 96-125/ 559
  • Inch 26 x 3,8-5,05
  • Sclaverand/Presta Valve

Bitte beachte: Please fill REVOLOOPs outside the tire with maximum 0.5 bar!



R E V O L O O P® Valves

Light and stable.
The valves developed by REVOLOOP are made of a special, high-strength thermoplastic polyurethane. They combine the highest technical demands with minimum weight and sophisticated design. The internally welded valve base plate protects the tube from damage caused by sharp edges on the valve bore in the rim and the dreaded valve breakage.

R E V O L O O P® Welding Technology

Virtually Seamless.
REVOLOOPs patent-pending welding process makes it possible for the first time to weld thermoplastic tubes with large wall thicknesses in such a way that an approximately flat seam can be produced. This technologically sophisticated process enables REVOLOOP to achieve perfect rolling comfort while at the same time providing maximum protection against snakebite and puncture failure.

R E V O L O O P® Material

Ecologically Responsible.
Thermoplastic polyurethanes are recyclable plastics. Since both REVOLOOPs tubing and the valve are made of TPU, R E V O L O O P® bicycle tubes can be completely recycled. Out of responsibility towards the environment.
