Optimization in numbers

increased stiffness-to-weight ratio

Task and challenge





Used material


Generative design to optimize a road and MTB crankset. The component was 3D printed in aluminium and, like all the components we design for additive manufacturing, uses sophisticated continuously variable geometry to use the material as effectively as possible, improving performance by decreasing weight while ensuring greater stiffness and more evenly distributed stress tension along the entire part.


Reconstruction of the original component using CAD software with the aid of 3D scanners

Motion analysis of the bicycle pedal and crown assembly to determine the loads acting on the component.

Preliminary finite element analysis and part preparation for topological optimization.

Thanks to the experience gained over the years we are able to optimize the components using the latest modeling software to get the best results from our work. Without forgetting the most important part of the engineer’s task, which is to evaluate the software proposals and choose the best one for the subsequent reconstruction and final verification.
