For riders competing in disciplines where absolute aerodynamic efficiency is critical, the engineering team at HUNT Bike Wheels saw the potential for wider, front and rear-specific rim profiles to provide considerable time savings while offering improved stability in crosswinds. Stability and predictable handling characteristics allow the rider to maintain a low, aerodynamic position on the bike despite changing wind conditions. Read More
The HUNT 7387 Aerodynamicist Carbon Disc minimizes steering forces, providing exceptionally stable and predictable ride characteristics, while offering extremely low aerodynamic drag.
Aerodynamicist rim profile, exclusively engineered and wind tunnel tested by HUNT's in-house engineering team, featuring a hooked and ETRTO-compliant tubeless-ready rim, designed for tubeless tire compatibility.
Includes FREE H_Care lifetime crash replacement for the first owners of these wheels. Read all about it here.

INTRODUCTION AND PROCESS
HUNT set out to create two wheelset systems for riders seeking the utmost in aerodynamics for time trial, triathlon and criterium racing, each set with a different front wheel depth, allowing riders to choose the best option for their riding. After two years of CFD modeling, prototyping, wind tunnel testing, and rider testing, HUNT created an 87mm deep rear rim profile maximized for the aerodynamic demands at the rear of the bike and designed to provide optimal lateral responsiveness and efficient power transfer. The two front wheel options offer riders category-leading aerodynamics and crosswind stability at different depths (73mm and 83mm depth), depending on their riding conditions, preferences, and goals.
KEY FEATURES
WHEELSETS ENGINEERED TO OFFER BOTH ALL OUT SPEED AND PREDICTABLE HANDLING IN CROSSWINDS.
