The Pinarello F5 race bike sharpens its aero profile with a redesigned downtube and a new elliptical steering tube, paired with an all-new E-TICR headset that routes cables through the front of the tube instead of the sides. A refined Aero Keel bottom bracket adds stiffness without adding bulk, and the frame's T700 UD carbon layup keeps road vibration in check even as the shape gets more aggressive. Shimano 105 Di2 handles shifting throughout. What Our Gearhead(R) Experts Are Saying:"Out of the saddle on a steep pitch, the frame stays stiff enough that every watt goes straight to the road, no wasted flex through the bottom bracket. Coming back down the other side at speed, the aero shaping holds its line through fast corners without feeling twitchy."Heads up!
