Shimano's GRX RX825 Di2 groupset handles shifting duties through a wired electronic system that delivers consistent actuation regardless of cable contamination or housing wear. The 12-speed rear derailleur pairs with an 11-36T cassette, while the GRX 820 crankset runs a 48/31T chainring combination that covers both fast pavement sections and extended gravel climbs. GRX RX820 hydraulic disc brakes provide stopping power through Center Lock rotors front and rear, with the modulation characteristics that Shimano developed specifically for mixed-surface riding where traction varies unpredictably.

Reserve wheels in a mixed-depth configuration optimize both aerodynamics and handling. The 40mm-depth front wheel pairs with a 44mm rear, a setup that Cervelo developed after discovering the bike's geometry could be fine-tuned for a 4mm tire width differential between front and rear. Zipp hub internals handle bearing duties on both wheels, with Center Lock rotor interfaces and tubeless-ready rim beds. Panaracer Gravel King SK tires in 700x40mm width provide grip across varying surface conditions, though the frame accommodates rubber up to 45mm for rougher terrain.

The geometry reflects Cervelo's road racing DNA adapted for gravel applications. Head tube angles range from 70.6 degrees on the smallest frame to 71.6 degrees on sizes 54 and larger, with the included TrailMixer flip-chip allowing fork offset adjustments that maintain consistent handling whether running 700c or 650b wheels. A 422.5mm chainstay length stays constant across all six frame sizes, keeping the rear end short enough for snappy acceleration while providing adequate mud clearance. The threaded BBright bottom bracket uses the T47a standard that Cervelo pioneered on the R5-CX, eliminating creak concerns while maintaining the outboard bearing placement that increases pedaling stiffness.
