The drivetrain is a full Shimano 105 R7170 Di2 groupset, running 12-speed electronic shifting front and rear. This is Shimano's semi-wireless setup: the shifters talk to the derailleurs wirelessly while a single internal battery powers the mechs through wires. You get the same shift logic and button feel as the higher Ultegra and Dura-Ace tiers, so the F3 shifts with the precision of a much more expensive bike. The crankset, front derailleur, cassette, and bottom bracket are all 105 Di2, keeping the drivetrain matched end to end.

Braking is handled by Shimano 105 two-piston hydraulic calipers front and rear, each paired with a 160mm rotor. That rotor size gives you the stopping power and heat management to haul the bike down from speed on a long descent without fade. Hydraulic actuation means light lever effort and consistent bite in wet or dry conditions.

The wheelset is DT Swiss A1800 30DB, a 30mm-deep aluminum disc wheel that balances aerodynamics against durability and repairability. Alloy wheels take abuse better than carbon at this price and are simpler to service, which makes them a sensible match for a first race bike or a training partner. MOST 30 tires mount up tubeless-ready, and the NEW MOST Ultra Light Custom axles use a 12x100mm front and 12x142mm rear thru-axle with tool-free removal, so you can pull a wheel roadside without digging for an Allen key.

The cockpit uses a JAGUAR CLAW ULTRA alloy handlebar with a CLAW ULTRA AERO alloy stem, an aluminum front end that saves cost over carbon while giving you a solid, no-drama contact point. The seatpost runs an FSC frontal seat clamp, and the saddle is a MOST Lynx MY26. The finishing kit here is where Pinarello trims cost to hit the F3's price without touching the frame or the drivetrain, which is exactly the right place to make those decisions. Finished in Interstellar Grey H230, this 2026 F3 gives you a race-legal Pinarello with electronic shifting and hydraulic discs at the accessible end of the range.
