ENVE SES 4.5 – Next Generation Tubeless Aero Road Wheelset

The ENVE SES 4.5 is the ultimate road wheel: fast, stable and incredibly versatile.
Originally designed for the cobbles and crosswinds of Paris–Roubaix , the new generation 4.5 redefines true speed on any terrain thanks to a lighter design, more efficient construction and aerodynamics optimised for large volume tubeless tyres.

Perfect for cyclists looking for a wheel capable of combining lightness for climbing, stability in crosswinds and aerodynamic performance for racing .

• Inner rim width: 25 mm

• Rim depth: 50mm (front) / 56mm (rear)

• External width: 32 mm

• Optimized for 27–28mm tires

• Compatibility: Tubeless ready tires only

• Maximum pressure (minimum tire): 80 psi / 5.5 bar

• Drilling: 24 spokes per wheel

• Brake: Centerlock disc

• Rim weight: 826g (411g front, 415g rear)

• Axles: 12x100 mm (front) / 12x142 mm (rear)

Designed for real speed

The SES 4.5 is the result of the Real-World Fast™ philosophy, born from the collaboration between ENVE and aerodynamicist Simon Smart .
Each wheel is designed to offer aerodynamic efficiency, stability and comfort on the road , even in crosswind or cobblestone conditions.

The differentiated shapes of the front and rear wheels optimize airflow:

• Front wheel: maximum stability and control in side winds

• Rear wheel: maximum aerodynamic efficiency and reduced drag

The result is a wheel that is faster than its deeper competitors , but also lighter and more manageable .

Construction and materials

The new high modulus carbon lamination reduces weight and improves spring rate, ensuring a smooth and responsive ride.
The hookless profile with patented Wide Hookless Bead™ technology offers:

• Pinch flat protection

• Greater safety and reliability of the tubeless system

• Better tire-rim fit

Each wheel is handcrafted in the USA , with individual quality checks to ensure absolute precision.

ENVE INNERDRIVE™ Premium Hub

At the heart of the SES 4.5 system is the new ENVE Premium Straight-Pull hub , a masterpiece of mechanical engineering designed for maximum smoothness, torsional stiffness and reduced maintenance .

Main features:

• Modular ratchet with 4 options: 40 / 60 / 80 / 100 teeth to customize the response

• Weight saving: 60g less than previous hubs

• Anti-twist spoke design , which prevents rotation and ensures constant tension

• Cold-worked and anodized 6061 alloy body

• Premium grade stainless steel bearings , resistant to corrosion

• Perfect Preload™ System: Optimal bearing preload for consistent smoothness and long life

Optimized tubeless performance

The hookless design allows for perfect heel hold, reducing rolling resistance and improving comfort, traction and control.
Thanks to the larger internal section (25 mm), the SES 4.5 supports modern 27–32 mm tyres , ideal for:

• Rough roads or granfondo

• Races on hilly or mixed courses

• Intensive use with lower pressures without risk of punctures

Synthetic technical characteristics

Ideal for

• Road and hill climb competitions

• Hilly or technical routes , with uneven asphalt

• Demanding cyclists looking for the perfect balance between aerodynamics, comfort and reliability

Strengths

• Developed for real-world racing conditions

• Superior aerodynamics even in crosswinds

• Tubeless system optimized for safety and comfort

• Stiffness and lightness ideal for climbing

• ENVE INNERDRIVE™ Premium hub with excellent mechanical efficiency

The ENVE SES 4.5 represents the high-performance “do-it-all” wheel: fast everywhere, always stable, precise in every situation .
A benchmark for those who want a single set of wheels capable of excelling on any route.
