      ROTOR crank 3D30 110 mm Compact for race

      Based on the successful 3D + crank rotor has developed the 3D30 crank system. The "Trinity Drilling System" was in 3D30 extended so that the crank has 3 holes in the entire length. With the bores material was removed from the center, the "neutral fiber" of the crank arm. This material contributes only to the least extent to sustainability of a component and can be omitted without any negative consequences. The necessary stiffness and stability is achieved with lightweight construction oversized outer diameter! The 3D30 has the perfect weight-stiffness ratio.
