Winner of a 2023 Design and Innovation Award, the Reserve 52|63 was designed to be the ultimate wheelset for sprint stages, triathlons, and anywhere with a straight long enough to make a break for it. The 52mm deep front slices through the air while still guaranteeing predictable handling in crosswinds, and the deep, 63mm rear helps you bank watts for those crucial final kilometers. It's the ultimate go fast wheelset, designed with Turbulent Aero technology. Turbulent Aero Technology For two years, we traveled the US, mapping different types of wind conditions, and then used this data to replicate real world conditions in the wind tunnel. All this work culminated in the creation of the first wheelset designed with Turbulent Aero technology. Design and Innovation Award Winner Reserve won a Design and Innovation Award in 2023 with the new 52|63 road wheelset. Used exclusively on the Cervelo S5, the 52|63 marks a milestone in the evolution of road wheel aerodynamics. "With the 52|63, Reserve have developed a set of aero wheels that usher in a new era of aerodynamic design and development. “- Design and Innovation Award Jury.
