Dogma F — Dura-Ace Di2 / Princeton Peak 4550

Torayca M40X frame, chosen for tensile modulus rather than for minimum mass. The down tube is rotated 3.5 degrees into an Aero-Keel profile at the bottom bracket, a change Pinarello measures at 1.2 per cent of drag across that junction, and the head tube nose has lost 8 mm of width against the previous generation.

The front end is a single assembly: elliptical steerer, differentiated headset bearings so the cables stay inside the frame, Onda fork at 47 mm of rake, and the MOST Talon Ultra Fast cockpit. Size 530 measures 542.4 mm of stack and 383.3 mm of reach on a 545 mm top tube.

The reference build is 6.780 kg without pedals, with Dura-Ace Di2 R9200 and the Princeton Peak 4550 — a hooked rim, 22 mm internally and 32 mm externally, that holds the tyre mechanically and carries no pressure restriction beyond the tyre's own rating.
