The SES 4.5 PRO redefines the benchmark for speed and weight, developed in collaboration with the world's top racers.

Progress at the highest level is incremental and iterative, and Enve Composites has redefined the benchmark SES 4.5 to deliver more speed and less weight. Winning everything from the Tour de France to World Championships and Ronde van Vlaanderen, Tadej elevated the SES 4.5 to be the most dominant wheel in the pro peloton, conquering cobbled classics, steep mountain summits, and the most grueling terrain with unparalleled speed. He prioritized aerodynamic supremacy over sheer weight savings, trusting the SES 4.5’s class-leading efficiency to deliver results. However, he and UAE Team Emirates envisioned something even more ambitious—a wheel that preserves the SES 4.5’s aero advantages while achieving the featherweight precision of elite climbing wheels.

Over a year of meticulous hub development, carbon laminate refinement, and manufacturing breakthroughs led to the creation of the SES 4.5 PRO. The designation "PRO" means it is a product developed in direct collaboration with the world’s top racers and represents the pinnacle of innovation—engineered and built for race-winning performance. The SES 4.5 PRO is the first product in the road line to receive this designation.

World Tour road racing requires an exceptional balance of aerodynamics, weight optimization, and compliance with governing bodies. The SES 4.5 PRO’s focus on the needs of professional racers requires compliance with the governing body’s equipment regulations. Depending on the course requirements, riders often choose 28 mm tires when road surface conditions are smooth and saving weight takes priority. With the 4.5 currently in the line where riders are most often pairing it with 30 mm tires, Enve Composites took advantage of the opportunity to create a purpose-built aero, climbing wheelset that is a refined tool for climbing at World Tour speeds.

The new rim design saves 50 grams per rim over the SES 4.5. This weight was saved by reducing rim depth and narrowing rim width. By removing material from under the Wide Hookless Bead, pinch-flat and impact function is preserved. A small hook is created as a result of eliminating material from the Wide Hookless Bead (critical tubeless dimensions preserved with new channel manufacturing technique). Actual inner-rim width is maintained, preserving tire volume and rolling-resistance performance. New materials allow for thinner sidewalls and channel.

The foundation of the Smart ENVE System (SES) philosophy is the concept of Real-World Fast performance that goes back to 2009 when Enve Composites partnered with leading aerodynamicist, Simon Smart. That means chasing maximum speed, but not at the cost of important performance attributes, such as weight, durability, and stability. The SES 4.5 PRO meets these requirements by preserving the majority of the SES 4.5’s patented shape and therefore its best-in-class aerodynamics and ride characteristics.
