Cervelo P5 Dura Ace Di2 Road Bike Black/Black, 54cm

What Our Gearhead(R) Experts Are Saying: "The P5 Dura-Ace Di2 combines race-proven aero design with flawless electronic shifting and integrated power measurement-this is the bike time trialists reach for when every watt counts."We choose the Cervelo P5 Dura-Ace Di2 when pure speed, data precision, and aerodynamic engineering matter. Its carbon TT frame boasts a modern fastback seatstay for enhanced comfort and better aerodynamics, while still maintaining blistering lateral stiffness. Adjustable via a one-piece front end, the cockpit offers up to 40mm of stack adjustment and +/- 30deg tilt on extensions for a perfectly tuned aero position. The wider armrests and monoriser improve control and comfort when pinned full gas. Shimano's 12-speed Dura-Ace Di2 drivetrain delivers instantaneous, silent shifting through R9180 shifters, R9250 derailleurs, a 54/40T crankset, and 11-34T cassette. Integrated 4iiii power meter lets you train smarter with precise data. Hydraulic braking via Dura-Ace calipers and 160mm rotors delivers controlled stopping without compromising aerodynamics. Rolling on Reserve 77 (front) and 88 (rear) carbon wheels with DT Swiss hubs, the bike achieves low drag and confident handling. Storage is cleanly integrated with Smartpak 400, a rear hydration mount, and optional aero bottle-everything designed to keep your focus forward and your watts in the bank.
