Enve G SES 4.5 Pro

The ENVE G SES 4.5 PRO represents the highest-performance evolution of ENVE’s versatile gravel aero platform, engineered specifically for modern gravel racing and ultra-fast mixed-surface riding. Building on the already highly regarded G SES 4.5 foundation, the PRO version introduces lighter rim construction, upgraded hub technology, improved responsiveness, and enhanced aerodynamic refinement aimed at elite riders and racers.

Unlike traditional gravel wheels that prioritize only durability or comfort, the G SES 4.5 PRO is built around ENVE’s “Real-World Fast” philosophy — the idea that true speed comes from optimizing the entire riding system, including aerodynamics, rolling efficiency, tire behavior, rider stability, vibration reduction, and handling predictability across rough terrain.

The wheelset is specifically designed around modern high-volume gravel tires and the increasingly aggressive speeds seen in elite gravel events. Rather than adapting narrow road aero rims for wider tires, ENVE engineered the G SES 4.5 PRO from the ground up to work efficiently with tires in the 35–50mm range, with the sweet spot typically falling around 40–45mm tires.

One of the defining features is the wheelset’s 25mm internal rim width, which significantly improves tire support compared to narrower gravel or road rims. The wider rim profile stabilizes the tire sidewalls during hard cornering and aggressive descending while also allowing riders to run lower pressures with greater control. This creates measurable gains in comfort, traction, rolling efficiency, and rider confidence on rough terrain.

Aerodynamics remain a major focus of the design. The G SES 4.5 PRO uses ENVE’s SES mixed-depth shaping philosophy with a shallower front wheel and deeper rear wheel to optimize both handling and aerodynamic performance.

• The front rim (~42mm depth) is designed to improve crosswind stability and steering control
• The rear rim (~49mm depth) prioritizes aerodynamic efficiency and speed retention

This mixed-depth approach gives the wheelset a notably calm, planted feel in windy conditions while still delivering meaningful aerodynamic gains during high-speed gravel racing and fast all-road riding.

Unlike many deep gravel wheels that become unstable once paired with larger tires, the G SES 4.5 PRO is aerodynamically optimized around real gravel tire dimensions. ENVE shaped the rim profile to maintain attached airflow with larger-volume tires installed, improving efficiency without sacrificing ride stability.

The carbon layup itself is also refined compared to the standard G SES 4.5. The PRO version uses lighter and more advanced carbon construction techniques to reduce rotational weight while maintaining impact durability for aggressive gravel use. The result is a wheelset that accelerates faster, climbs more efficiently, and feels more responsive under hard efforts while still retaining excellent compliance over rough surfaces.

Ride quality is one of the strongest aspects of the wheelset. While highly laterally stiff during sprinting and climbing, the rims also damp vibration effectively, reducing fatigue during long gravel races and endurance events. This smoother ride feel helps maintain traction and rider efficiency on washboard roads, rocky sectors, and rough mixed terrain.

The wheelset is fully tubeless-ready and uses ENVE’s hookless rim technology. Hookless construction allows tighter manufacturing tolerances, improved impact strength, reduced weight, and more consistent tire seating when used with approved tubeless tires. It also creates a smoother tire-to-rim interface that improves aerodynamics and airflow stability.

Rim Specifications

Aerodynamic Design Philosophy

The G SES 4.5 PRO is heavily focused on maintaining efficiency with wider gravel tires installed.

Key aerodynamic features include:

• SES mixed-depth front/rear rim shaping
• Tire-specific aero optimization for gravel widths
• Improved airflow attachment around larger tires
• Enhanced crosswind stability compared to deeper gravel wheels
• Reduced steering disturbance in gusty conditions
• Efficient airflow transition between tire and rim

This makes the wheelset significantly faster than shallow gravel wheels while remaining easier to handle than ultra-deep gravel aero options.

Ride Characteristics

The ride feel of the G SES 4.5 PRO is best described as:

• Fast and highly responsive
• Smooth over rough terrain
• Stable during high-speed descending
• Precise while cornering at low tire pressures
• Efficient during long sustained efforts
• Balanced between stiffness and compliance

The wheelset performs exceptionally well in:

• Gravel racing
• Fast endurance gravel riding
• Mixed-terrain road riding
• High-performance all-road builds
• Long-distance events and ultra-endurance racing

Hub System – ENVE INNERDRIVE PRO

A major upgrade on the PRO model is the inclusion of the ENVE INNERDRIVE PRO hub system, ENVE’s top-tier in-house hub platform designed specifically for elite-level performance.

Compared to the standard INNERDRIVE hub, the PRO version includes:

• Reduced internal drag
• Lighter hub shell construction
• Higher-end bearing system
• Faster engagement response
• Improved power transfer feel
• Lower rotational weight
• Enhanced sealing for all-weather performance

The hub uses a premium ratchet drive mechanism optimized for durability and quick engagement while remaining smooth and efficient under load.

Additional hub features include:

• Straight-pull spoke interface
• Centerlock rotor compatibility
• Tool-free freehub removal
• Serviceable internal ratchet mechanism
• Oversized bearings for durability and stiffness

Available Freehub Body Options

The G SES 4.5 PRO is commonly available with multiple freehub standards:

Spoke Configuration

Tire Pairing Recommendations

The wheelset performs best with modern gravel race tires and high-volume all-road tires such as:

• ENVE SES tires
• Continental Terra Speed
• Pirelli Cinturato Gravel RC
• Panaracer GravelKing X1 R
• Rene Herse endurance casings
• Schwalbe G-One RS

Overall Performance Summary

The ENVE G SES 4.5 PRO is designed for riders who want one of the fastest and most refined gravel wheelsets available while still maintaining real-world versatility and ride quality.

Compared to the standard G SES 4.5, the PRO version delivers:

• Lower weight
• Faster acceleration
• Reduced hub drag
• Improved responsiveness
• More premium hub internals
• Higher-end race-focused performance feel

Compared to ultra-deep gravel wheels like the G SES 6.7 PRO, the 4.5 PRO offers:

• Better versatility
• Easier crosswind handling
• Improved mixed-terrain adaptability
• Greater suitability for rougher gravel conditions

The result is a wheelset that excels not only in elite gravel racing, but also in fast endurance riding, all-road riding, and long mixed-surface adventures where efficiency, comfort, and control all matter equally.
