Reserve 77|88 – The World's Fastest Time Trial and Triathlon Wheelset

The Reserve 77|88 represents the maximum expression of modern aerodynamic technology applied to competitive cycling.
Developed with the new Turbulent Aero Technology , they are designed for those seeking absolute speed and impeccable stability in real wind conditions, such as those encountered in triathlons or the most demanding time trials.

Uncompromising performance

Whether it's dominating the Queen Ka'ahumanu Highway or improving your local time trial record, the Reserve 77|88 delivers a real aerodynamic advantage .
Their mixed profile design (77 mm front and 88 mm rear) allows you to maintain total control even at high speeds, minimizing air resistance and overall weight.

Turbulent Aero Technology

This innovative technology is the result of two years of field research under various wind conditions in the United States.
The collected data was used to simulate turbulent winds in a wind tunnel, creating the first wheelset designed specifically for real-world turbulence .

Main advantages:

• Optimized aerodynamics in variable wind conditions

• Greater directional stability and lateral control

• Reduced drag and improved efficiency during top speed phases

Mixed profile and asymmetrical rear

The Reserve 77|88 adopt a differentiated profile:

• 77 mm front → greater control and aerodynamic stability

• 88 mm rear → optimal stiffness and traction

The asymmetric rear wheel improves the distribution of spoke tension, making the wheel more solid, resistant and performing even under prolonged stress.
