Princeton Peak 4550 demo blackDevelopment priorities were to improve on the already exceptional aerodynamic characteristics and the strength and stiffness of the previous generation Peak 4550. To create the next evolution of a wheelset that is light, responsive, and fast accelerating for the climbs. On the descents, a wheelset that is predictable and sharp handling. And in the valleys, a wheelset that is aerodynamic and impervious to crosswinds. Internal rim width has been
