Through all that we have learned from our original RS5/6 model, we have identified that the most balanced profile is 55mm. Even though the RS5/6 staggered profiles of a 50mm front and 60mm rear wheel provided some compelling performance. Overall, the 55mm rim profile provided what we believe is the most optimized depth for peak aerodynamics at a multitude of different yaw angles. When rim depth increases past 60mm, they are faster at more closed angles, but less efficient at wider yaw angles. The 55mm depth also provides less of weight penalty, resulting in a perfectly balanced aero focused wheelset, with little compromise.
