Exceptional dirt and water resistance compared to commonly available bottom brackets on the market for fat bikes
grinded surfaces of the seals for the best possible, permanent sealing function against dirt, water and electrolyte drinks, which can clog the bearings and lead to premature bearing wear or damage.
Maintenance-free, a bicycle lifetime long
Preload sleeve for transmitting axial preload forces caused by the pedal crank. Additionally the sleeve seals the roller bearings on the inner side. This means that there is no longer any risk of excessively preloaded bearings inside the bottom bracket, which can lead to premature bearing wear or even damage.
withstands bike cleaning with high-pressure water cleaners (60°C, 100 bar water pressure, 40 cm distance to the lance) without any problems
compatible with Ø 30mm spindles and commercially available cranks such as FSA, Rotor, Aerozine etc.)
suitable for bottom bracket shells according to the T47 standard with M47x1-thread and 132mm shell width.
