The Free Aero RC knicks are Castelli's flagship race short, refined over many generations to be just as comfortable on a long ride as in a sprint. High-compression fabric supports the muscles while keeping the cut simple, with fewer panels and seams than the previous generation.
The seamless pad is soft against the skin, and the raw-cut leg openings stay in place without silicone grippers, so there are no gripper lines.
