Even though the CL 50 is similar in weight to many wheels in the lightweight category, aerodynamics came at the forefront of the development. With this, Specialized jumped headlong into Computational Fluid Dynamics computer modeling to arrive at various rim shapes that could make the CL 50 as fast and light as possible. It took a while, but they narrowed the rim shape down to three contenders that were then CNC machined into rims, built into wheels, and put into the Win Tunnel.
