Handling stays sharper than typical endurance geometry would suggest. The head tube angle measures a racy 72 degrees, just half a degree shy of the brand's race bikes. The chainstays measure 415mm throughout the size range , so the X3 still turns in with intent rather than the slow steering common to comfort-oriented frames. Pinarello says this is compact enough to maintain a good level of responsiveness, but nevertheless elongates the wheelbase slightly to improve stability . Thanks to the fork's slightly raised crown, and the frame's elongated chainstays, clearance is rated to 32mm-wide tyres , and the Onda fork uses Pinarello's proprietary 1.5" steerer to add compliance and accommodate wider rubber.

Shimano 105 R7170 Di2 handles shifting and braking, with the 12-speed semi-wireless system delivering the same shift logic as Ultegra and Dura-Ace at a more accessible tier. The 105 hydraulic disc calipers clamp 160mm rotors front and rear, providing consistent modulation in wet weather and on long descents where rim brakes fade. The drivetrain uses a 50/34 compact crankset paired with an 11-34 cassette, giving a wide gear range that handles steep climbs without compromising top-end speed on flatter terrain. The X-Series also features fully internal 'TiCR' cable routing, which the brand says saves up to five watts compared to a "conventional setup" , keeping the front end clean and uncluttered.

Fulcrum Racing 800 DB wheels carry Pirelli P7 700x28C tires as the stock build. The aluminum wheelset is built for daily-use durability rather than weight savings, which leaves an easy upgrade path to lighter carbon hoops if the rider wants to sharpen acceleration. The cockpit pairs a Most Jaguar XA Aero TiCR handlebar with a Most Tiger Aero alloy stem, and the proprietary Pinarello aero carbon seatpost uses the 3D-printed titanium, integrated seatpost clamp design from the Dogma F and new F-Series bikes . A Prologo Dimension NDR saddle finishes the build, and the Italian threaded bottom bracket simplifies long-term service compared to press-fit standards.
