The ENVE G SES 4.5 Pro Front Wheel is a 700c carbon gravel wheel designed to deliver the best available balance of aerodynamics, weight, and handling dynamics across real-world gravel terrain. The G SES (Gravel Smart ENVE System) designation places this wheel within ENVE's gravel-specific wheel development programme, which addresses the distinct demands of gravel riding - varied surface types, mixed terrain, and conditions that shift between fast road sections and rougher unpaved stretches within a single ride.
The 4.5 in the name refers to the rim profile - a 45mm front depth that positions this wheel in the mid-deep section range. ENVE built the G SES 4.5 on the foundation of the SES 4.5's proven aerodynamic design, adapting it specifically for gravel applications to deliver top performance in aerodynamics, handling dynamics, versatility, and weight savings compared to gravel aero wheels of equal or greater rim depth. The exception noted by ENVE is the G SES 6.7, which exceeds the 4.5 in certain metrics as the deeper profile option in the G SES range.
This is the front wheel only. The 700c diameter, 24-hole drilling, 12mm thru-axle at 100mm front spacing, and centerlock disc interface are the key specifications - confirm all four match your fork before purchase.
ENVE describes the G SES 4.5 as delivering balanced aerodynamic and weight performance for real-world speed across all terrain at the lightest weight possible for this rim depth and profile. The phrase "real-world speed" is significant - it reflects ENVE's design philosophy for the G SES range, which prioritises performance under the varied and unpredictable conditions of gravel riding rather than optimising purely for controlled wind-tunnel test conditions.
Handling dynamics are explicitly called out as a top performance category for the G SES 4.5 - not only aerodynamics and weight. For a front wheel specifically, handling dynamics are the most critical performance characteristic. A front rim that is too deep or too aerodynamically aggressive can create instability in crosswind conditions, reducing rider confidence on technical gravel descents or in exposed riding environments. The G SES 4.5's design takes handling into account as an equal priority to aerodynamic gain, reflecting an understanding that a gravel rider needs to trust their front wheel across conditions that a pure road race environment would not present.
The four key specifications of this wheel are its compatibility parameters. The 700c diameter is the standard gravel wheel size for riders using this rim diameter rather than the alternative 650b configuration available in the G SES range. The 24-hole spoke count provides a stiff and responsive wheel build suited to performance gravel riding where compliance is provided by the tyre rather than the wheel's spoke count. The 12mm thru-axle at 100mm front spacing is the standard fitment for modern disc brake road and gravel bikes. The centerlock disc interface requires a centerlock rotor - not a 6-bolt rotor - confirm your fork, caliper, and rotor are all centerlock compatible before purchase. The rotor is not included.
This listing is for the front wheel only. The matching G SES 4.5 rear wheel is available separately.
The G SES 4.5 uses a 45mm rim depth profile, placing it in the mid-deep section range for gravel aero wheels.
The wheel uses a 12mm thru-axle at 100mm front spacing - the standard fitment for modern disc brake gravel and road bikes.
The wheel uses a centerlock disc interface. A centerlock rotor is required and must be sourced separately - it is not included with the wheel.
ENVE gravel wheels are typically Tubeless Ready - confirm tubeless compatibility in the full product specification on the ENVE website or contact Trek Bikes Florida before purchase, as the manufacturer information supplied does not explicitly confirm this detail.
ENVE notes the G SES 6.7 exceeds the 4.5 in certain metrics as the deeper profile option in the range. The 4.5 delivers top performance in aerodynamics, handling dynamics, versatility, and weight compared to other gravel aero wheels of equal or greater depth, with the 6.7 being the exception within the G SES family itself.
The front wheel has 24 holes.
