The ENVE G SES 4.5 Pro Rear Wheel is a 700c carbon gravel rear wheel built on the same G SES (Gravel Smart ENVE System) platform as the front wheel, with the rear-specific specifications that matter for drivetrain compatibility and rear axle interface. This version uses a 12mm thru-axle at 142mm rear spacing and an SRAM XDR freehub body - the freehub standard required for SRAM's 12-speed AXS cassettes including the RED XG-1290 and Force/Rival AXS cassette ranges. Confirm that your SRAM cassette uses an XDR interface before purchase, as the standard SRAM XD freehub and Shimano HG freehubs are different standards not compatible with XDR cassettes.
For riders building a complete G SES 4.5 gravel wheelset, the matching front wheel is available separately. The front wheel uses a 12mm thru-axle at 100mm front spacing, while this rear wheel uses 142mm - the standard configuration for modern disc brake gravel and road bikes.
The G SES 4.5 rear wheel is built on the same 45mm rim profile and G SES design philosophy as the front - delivering top performance in aerodynamics, handling dynamics, versatility, and weight savings compared to gravel aero wheels of equal or greater depth, with the G SES 6.7 being the only exception within the G SES family itself.
The SRAM XDR freehub body is a specific interface designed for SRAM's 12-speed Eagle and AXS road cassettes. XDR is dimensionally different from the standard SRAM XD freehub used for 10 and 11-speed SRAM cassettes, and is not compatible with Shimano HG cassettes. For riders running SRAM RED AXS, Force AXS, or Rival AXS 12-speed drivetrains - where the XG-1290 or equivalent XDR cassette is used - this rear wheel is the correctly specified option. Riders using Shimano or other drivetrain standards will need to confirm freehub compatibility before purchase.
The 12mm thru-axle at 142mm spacing is the standard rear axle configuration for modern disc brake gravel bikes. The centerlock disc interface requires a centerlock rotor - not a 6-bolt rotor. A rotor is not included with the wheel and must be sourced separately. Confirm that your frame, caliper, and rotor are all centerlock compatible before purchase.
The rear wheel uses 24-hole drilling - the same as the front - providing a stiff and responsive wheel build suited to the power transmission demands of a driven rear wheel on varied gravel terrain. At the rear, spoke count and wheel stiffness directly affect how efficiently pedalling power is transferred to forward motion, and 24 holes provides the lateral stiffness required for a performance gravel rear wheel without unnecessary weight from additional spokes.
The G SES 4.5's balanced approach to aerodynamics, handling dynamics, and weight at a 45mm rim depth applies as meaningfully to the rear wheel as the front - the rear wheel contributes significantly to the overall aerodynamic profile of the complete wheelset, and a mismatched depth between front and rear creates an inconsistent aerodynamic system. Running matched G SES 4.5 front and rear wheels delivers the complete aerodynamic and handling package the G SES 4.5 was designed to provide.
This listing is for the rear wheel only, with 12mm thru-axle at 142mm rear spacing and an SRAM XDR freehub body. The matching front wheel with 100mm spacing is available separately.
This version uses an SRAM XDR freehub body, required for SRAM 12-speed AXS cassettes. It is not compatible with standard SRAM XD, Shimano HG, or other freehub standards.
The rear wheel uses a 12mm thru-axle at 142mm spacing - the standard configuration for modern disc brake gravel and road bikes.
The wheel uses a centerlock disc interface. A centerlock rotor must be sourced separately as it is not included.
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.
The rear wheel uses a 12mm thru-axle at 142mm spacing and an SRAM XDR freehub body. The front wheel uses 12mm thru-axle at 100mm spacing and has no freehub. The rim profile and G SES 4.5 design are the same across both.
The rear wheel has 24 holes, providing stiffness and responsiveness suited to the power transmission demands of a driven rear wheel.
