Reserve 48 GR carbon wheels with DT Swiss 370 hubs provide a performance-focused wheelset, matched to high-volume 700 x 45C WTB Vulpine tyres.

Shimano GRX Di2 Electronic Shifting
Shimano GRX RX825 Di2 controls give the Aspero wireless electronic shift inputs from a gravel-specific cockpit. At the rear, the GRX RX827 SGS derailleur manages the 12-speed drivetrain, providing electronic shifting across the wide-range cassette.
This build uses a 1x configuration, removing the front derailleur and keeping the drivetrain straightforward while retaining the gearing range needed for changing gradients and varied gravel terrain.
10-51T Wide-Range Gravel Gearing
A Shimano XT M8200 10-51T 12-speed cassette gives this Aspero a particularly broad spread of gears. The 51T largest sprocket provides a significantly lower climbing option for steep or loose terrain, while the 10T smallest sprocket supports higher speeds at the other end of the range.
The cassette is paired with a Shimano GRX RX820 chainset, bringing Shimano’s gravel-specific component family together with wide-range mountain bike gearing at the rear.
Reserve 48 GR Carbon Wheels
Reserve 48 GR carbon wheels are a significant part of this build’s performance specification. Both wheels use DT Swiss 370 hubs with 24-spoke construction, Centerlock disc interfaces and tubeless-compatible rims.
WTB Vulpine TCS Light Fast Rolling Dual DNA SG tyres measure 700 x 45C, providing a high-volume gravel setup for varied surfaces. The 120 tpi tyre construction complements the performance-focused Reserve wheelset.
Carbon Gravel Cockpit
Cervelo’s AB09 carbon handlebar uses a 31.8 mm clamp and 16 degree flare, giving the Aspero a gravel-specific drop-bar cockpit. It is paired with the Cervelo ST36 alloy stem.
A Fizik Vento Argo X3 saddle and Cervelo SP19 27.2 mm carbon seatpost complete the main contact points, adding another carbon component to this higher-spec Aspero build.
T47 Threaded Bottom Bracket
The Aspero uses Cervelo’s T47 BBright bottom bracket format, with this build fitted with an FSA unit for the Shimano GRX chainset’s 24 mm spindle. The threaded interface provides a practical, serviceable bottom bracket arrangement for a bike intended to cover demanding gravel mileage.
Storage and Accessory Mounts
Long rides and gravel events often require more than just bottles, so Cervelo equips this Aspero with useful storage and mounting options. A Smartpak Top Tube Storage Bag 400A provides easily accessible space for ride essentials, nutrition or small tools.
Cervelo’s Front Computer/Accessory Mount 265 and Rear Accessory Mount are also included, providing dedicated mounting points for additional equipment.
Who It’s For
The Cervelo Aspero GRX RX825 Di2 2027 is for gravel riders who want Shimano electronic shifting combined with genuinely wide-range 1×12 gearing. Its GRX Di2 drivetrain, 10-51T cassette, Reserve 48 GR carbon wheels and 700 x 45C WTB tyres make it particularly suited to fast gravel racing and long mixed-surface rides where efficient shifting and a broad climbing range are priorities.
