WHEN DEEP ISN’T DEEP ENOUGH
Like a speed-seeking missile, the SES Disc wheel is there to provide the greatest aero advantage for the triathlete or time trial racer. Designed to be paired with another aero standout, the SES 7.8.

The SES Disc wheel is the outright fastest rear wheel available. It is the culmination of nearly five years of development. During this process we considered not only aerodynamics but also rolling resistance, braking, and ride quality. The SES Disc is available as a tubeless clincher in both rim and disc brake models.

To achieve the bar-raising performance of the SES Disc, we developed every aspect: aerodynamics, tubeless compatibility, construction, and braking. Like all SES products, the SES Disc was developed using state-of-the-art Computational Fluid Dynamics analysis by our long-term partner and consultant aerodynamicist, Simon Smart of Smart Aero Technology. Prototypes were assessed in the Mercedes-AMG Formula One wind tunnel and the subtle shape iterated to deliver class-leading aerodynamics at high race speeds.

Practical considerations were also taken in development, like strength from impacts and accidents. The use of spread-tow technology helps to prevent punctures from projectiles through the carbon while riding or transporting, giving you peace of mind on and off the bike.
