Turbulent Aero Technology

The 77|88 Turbulent Aero represents a major advancement in road wheel aerodynamics. Drawing on real-world data, this technology enables the design of a wheelset that is stable, fast, and performant in all conditions.

Differentiated profiles and offset rear rim

Thanks to a mixed rim profile – 77 mm at the front and 88 mm at the rear – the 77|88 TA optimizes stability, weight, and aerodynamics. Its asymmetrical rear rim offers greater rigidity and increased strength, ensuring reliable and durable performance over time.

Built for speed

After two years of research on wind conditions across the United States, the collected data was used to recreate these conditions in a wind tunnel. This approach allowed Reserve to develop the first wheelset to truly harness the potential of Turbulent Aero technology.
