Cervelo has evolved their P-series bikes with updated frame designs and complete build packages that enhance aerodynamics, improve drivetrain efficiency and overall torsional resistance from the headtube back through the frame. Long gone is the P3 designation, with that frame level simply becoming the P-Series. Built here as a mid-range complete event bike, this Cervelo P Ultegra Di2 Bicycle triathlon/aero package demonstrates significant improvements with an Ultegra Di2 12-Speed drivetrain build featuring a Riderever hydraulic braking system and Reserve Carbon 50 wheelset. The build includes aero storage and hydration accessories that help to reduce drag while offering simplicity and convenience as part of this impressive complete package.

Cervelo created the all new P-Series for a single mission: to go from Point A to Point B as quick possible. The engineers went back to the drawing board of the P3, improving every facet. The P-Series features better air economy, improved stiffness and comfort. It has been designed with discipline, focus, style and swagger with every pedal stroke propelling human and machine through the air with ease, turning watts into wins. How? Start with torsional frame stiffness. The P-Series frameset is 18% stiffer at BB than P3. Headtube and general tube refinement from dropout to dropout combine with that BBright Asymmetric bottom bracket zone and the result is a borderline ridiculous 30% improvement in overall torsional stiffness. The P3 had been one of the most decorated framesets in the triathlon world, so to see such massive improvements is wholly impressive, and we haven't even mentioned that the P-Series frame is 9% lighter, or examined aerodynamics yet.

A quick look at the P3 and P-Series designs allows the viewer to see the similarities, but a closer look demonstrates the aerodynamic refinements that deliver impressive results. Clearly Cervelo has also been able to develop a new carbon lay-up to deliver the impressive stiffness and lighter weight, but those are generally internal. Aerodynamic changes can be very subtle but seen in three areas; frontal shapes, transitions from tube to tube and juncture to juncture, with the third being the integration of components and aero accessories- all taken together with proven wind tunnel and CFD testing, but also with respect to how the rider position and physical interaction impact the true overall aerodynamic picture. Cervelo has tested the P-Series at 26g faster than P3 bare, and 18g faster loaded. Every improvement, every detail, every struggle all serve to create a faster design, with many incremental changes adding up to more speed, delivered more efficiently, saving you watts of effort as you go faster.

There are some key points to mention. While the frame cable routing system is fully internal, and mostly integrated, Cervelo made a strategic decision to allow for the use of any standard stem, allowing for easier service, fit adjustments, and lower cost. The frame itself represents the deep history of Cervelo's engineering: the integrated fork, headtube, Dropped Downtube system, and the sculpted Extended Seattube Cutout that shields the rear wheel, the BBright concept. Cervelo modified the frame geometry as well to allow for increased stack and reach range. Attention to detail includes the coordinated storage and hydration features of the P-Series. The toptube Smartpack 400 bag system fills in perfectly behind the sleek cable routing entry, offering small item storage that is easily accessible while riding. The Aerobottle 500 sits flush against the downtube, blending into the seattube at the bottom bracket, with a shape that carries and guides are cleanly off the back. The massively adjustable aero carbon seatpost now has a mount off the back for a rear bottle mount. All of these features and selections are part of the full aero package.

With this complete P-Series Ultegra Di2 complete bike, the integrated aerodynamics reign, especially the wheelset, aerobar set-up and disc braking control components. The standard Ultegra R8100 12-speed 52-36T crankset, 11-30T cassette, M8100 chain, R8150 Di2 front and rear derailleurs keep the drivetrain smooth, quiet and efficient. Cervelo employed the 12-Speed compatible R9150 and R9150 Dura-Ace aero shift buttons on the Zipp Vuka Bull base bar mounted Riderever disc brake levers and Vuka Carbon arm extensions. Perhaps the biggest surprise is Cervelo's use of this Riderever Trivia disc braking system, which is sleek, clean functional, and delivers braking control and feel with 160mm disc rotors.

The Zipp Vuka carbon base/aero bar set-up offers great adjustment and variety, with comfortable forearm pads. The 31.8mm diameter bar is attached with Cervélo's standard Alloy Stem. Mounted to the top of the SP23 Aero Carbon Seatpost is the popular Prologo Dimension T4.0 saddle. Finishing the build strong, Cervelo opted for the partner's Reserve Carbon 50|50 TL Disc wheelset for excellent efficiency, speed, and acceleration. These are equipped with the with high mileage Vittoria Zaffiro Pro V Folding G2.0 25c clincher tires and tubes. Built to be fast, powerful, and efficient, the P-Series Ultegra Di2 Bicycle is competition ready, whether in your next Time Trial or triathlon event.
