Rim shape optimization using AI and CFD analysis
In order to find, for each model, the rim shape that has the least air resistance and is less susceptible to crosswinds, we conducted rim design using CFD* analysis and AI. By letting AI search for rim shapes, we were able to conduct large-scale analysis of rim shapes, including ones that humans could never think of. Accordingly, we were able to develop rim shapes that have the best aero performance required for respective models.

Wind tunnel testing
We conducted wind tunnel tests to confirm the validity of the analysis and the prototype performance using actual products. In addition to the measurement of a wheel alone, we conducted measurement under different tire conditions and measurement with the entire bike and rider included. Thus, we collected a wide range of data, which was effectively used to develop not only wheels but also various other components.
