What It Is
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.
Who It's For
The SES Disc wheel is for elite and professional time trialists and triathletes who are looking for maximum efficiency for race courses where average speeds will exceed 27mph.
Why We Made It
Beyond 27mph, at the high speeds experienced by professionals and the best amateur athletes, a rear disc wheel is the most aerodynamic solution. Every aspect of efficiency must be considered at these speeds, and we spared no expense in development.
Some will ask why it has taken so long for ENVE to develop a rear disc. Simply, we only wanted to make a disc that delivers a significant step forward in performance and ride quality over our flagship SES 7.8. We took our time to get it right.
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.
Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
