Reserve 52|63 Turbulent Aero
Winner of the prestigious 2023 Design and Innovation Award, the Reserve 52|63 carbon road wheelset is the ultimate aerodynamic weapon for sprint stages, high-speed criteriums, and triathlons. Designed specifically for riders looking to make a break for it, this wheelset utilizes Reserve's groundbreaking Turbulent Aero technology to cheat the wind in real-world conditions.
By employing a mixed-depth profile, the 52|63 gives you the best of both worlds. The slightly shallower, 52mm front rim slices through the air while guaranteeing predictable, confident handling in gusty crosswinds. Meanwhile, the massive 63mm rear rim acts as a sail, helping you bank crucial watts for the final kilometers of your race.
Optimized for modern 28c to 35c road tires, the wide stance of the 52|63 ensures incredibly low rolling resistance and a seamless aerodynamic transition from the tire sidewall to the rim. Built with highly serviceable standard J-bend spokes, external nipples, and backed by Reserve's lifetime warranty, this is the definitive go-fast wheelset for uncompromising speed.

Key Features
Turbulent Aero Technology: For two years, Reserve traveled across the US mapping highly variable wind conditions, using the data to replicate real-world scenarios in the wind tunnel. All this work culminated in the creation of the first wheelset specifically engineered for Turbulent Aero—designing the fastest, most stable wheelset for real riders in real-world, gusty conditions.
Design and Innovation Award Winner: Reserve took home a Design and Innovation Award in 2023 with the 52|63 road wheelset. Used exclusively on the Cervelo S5 at the highest levels of the World Tour, the 52|63 marks a milestone in the evolution of road wheel aerodynamics. As the award jury noted: "With the 52|63, Reserve have developed a set of aero wheels that usher in a new era of aerodynamic design and development."
