Where Cutting Edge Engineering Meets Podium-Winning Pedigree

With direct input from Tadej Pogačar and UAE Team Emirates—XRG over two seasons, we’re pleased to introduce the SES 4.5 PRO—a wheel that has already amassed 25+ victories this season. It is designed for cyclists seeking the ultimate wheelset, where low weight, aerodynamics, and rolling efficiency meet.

PRO LEVEL PERFORMANCE

PRO in the name 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 second product in our road line to receive the designation after the SES Aero PRO One-Piece Handlebar.

INNERDRIVE GOES FEATHERWEIGHT

The core of the 4.5 PRO wheel is the PRO Hubset, which brings ENVE’s proven INNERDRIVE technology to an ultralight straight-pull hub shell. At just 281 grams for the hubset (rear 194 grams, front 87 grams), the INNERDRIVE PRO goes head to head with the lightest hubs out there without sacrificing the stiffness required by the world’s best.

The Wheel That Tadej Asked For

VICTORY DRIVEN BY INNOVATION

The SES 4.5 PRO was created after over a year of meticulous hub development, carbon laminate refinement, and manufacturing breakthroughs. 

When speed matters most

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 took advantage of the opportunity to create a purpose-built aero, climbing wheelset that isn’t intended to be the jack-of-all wheel, but rather a refined tool for climbing at World Tour speeds.

real-world FAST

The foundation of the Smart ENVE System (SES) philosophy is the concept of Real-World Fast™ performance that goes back to 2009 when we partnered with leading aerodynamicist, Simon Smart.

Aerodynamic Performance

Real-World™ Fast 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. Simply put, after nearly 10 years, the SES 4.5 shape continues to punch above its depth. That’s how ENVE came to be the wheel partner of UAE Team Emirates. Unbeknownst to ENVE, UAE had purchased the leading wheels on the market and independently tested them in the wind tunnel and on the road. The rest is history.

ULTRALIGHT PRO INNDERDRIVE HUB

Ceramic Bearings

Bearing drag is influenced by numerous factors, including the bearing seals, ball bearings, races, and carrier. Other factors such as manufacturing consistency, tolerances, grease content and viscosity play roles as well. To control each of these variables, we worked with a leading bearing vendor to create what we believe to be the best ceramic wheel bearing available. ENVE’s new PRO Ceramic Bearings feature hardened stainless-steel races that won’t rust, grade 5 ceramic balls, non-contact seals on the interior-facing bearing for drag reduction, and a semi-contact seal on the outside to keep out the debris. ENVE Pro Ceramic Bearing solution is one that feels fast in-hand and promises reliability in the long run.

Ceramic Tech:

  • Ceramic balls with a sphericity of .000005 – inch (Grade 5)
  • Low-friction polyamide bearing cages improve durability, reduce
    rolling resistance, and corrosion
  • Hardened stainless steel races
  • Low-contact outboard seals reduce debris ingress
  • Non-contact inboard seals reduce drag

Innerdrive pro tech

Utilizing the same INNERDRIVE technology featured in the Premium Straight-Pull hubs that have been raced in the World Tour for their second season, the PRO hubset receives the very hop-up kit developed for our professional teams. This includes a light-action ratchet spring for drag reduction and a 40-tooth count ratchet. Like the Premium Straight-Pull hubs, the PRO hub uses the same spoke alignment feature to reduce spoke twisting. 

Hub Tech:

  • Ultralight hub shell
  • Ultralight 40t PRO ratchet and spring kit
  • ENVE PRO Ceramic Bearings
  • 60 grams weight savings over
    Premium INNERDRIVE.
  • 281 grams for the hubset (rear 194 grams, front 87 grams)

SES 4.5 PRO CONSTRUCTION

New rim design saves 50 grams per rim over the SES 4.5.

new rim design

  1. Reduced rim depth
  2. Rim width is narrower
  3. By removing material from under the Wide Hookless Bead ™ pinch-flat and impact function is preserved
  4. A small hook is created as a result of eliminating material from Wide Hookless Bead ™ (critical tubeless dimensions preserved with new channel manufacturing technique)
  5. Actual inner-rim width is maintained, preserving tire volume and rolling-resistance performance
  6. New materials allow for thinner sidewalls and channel
