ROTOR crank Flow - 130 mm bolt circle diameter
The Flow crank combines the technical refinements of 3D + cranks with an aerodynamically optimized shape. Using modern software the wind resistance of the crank has been minimized in order to provide road cyclists, time trialists and ambitious Triathlonathlethen a real and legal advantage! The chainring spider is provided with twice the number of holes for the chainring bolts. Thereby, the Rotor Q-Rings that are designed to ensure a more efficient passage can be fine position to still be able to achieve better results.
The arms of RotorFlow crank are holgebohrt 3 slots. Drilling save weight, thanks to the crank arms bulky executed these still offer a very high stiffness!
