      Based on the successful 3D crank rotor has built the 3D + crank system. The "Trinity Drilling System" was + extended in 3D 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!
