This Prince Disk bicycle is perfectly matched with 2nd generation 11-speed Ultegra R8070 Di2 Hydraulic Disc and R8050/8000 components. The E-tube Di2 system is fully modular, easy to service, diagnose, set-up, and charge. Obviously the front and rear derailleurs are the R8050 Di2 options, both optimized for the R8000 physical drivetrain. The FD mates perfectly with the new offset of the chainrings, as well as offering great clearance for framesets with larger tires. The RD features the MTB inspired Shadow design and new linkage system. An internal seatpost battery is used, and the control and charge is set-up via the E-Link insert in the downtube. All routing is internal, clean, simple, and accessible. With R8070 Shimano introduced their first combination of Di2 with a full Ultegra-level hydraulic disc brake system. The R8070 Di2/hydraulic dual control levers are sleeker, with a new pivot point for the brake lever, and easy-to-service with access to the mineral oil hydraulic system. The R8070 road brake flat mount calipers are lighter, with cleaner routing and mounting, and optimized for the power and feel required for road disc braking with the Center Lock RT-81 160mm IceTech disc rotors.

The 50-34T R8000 crankset, Italian thread external bottom bracket cups, chain and 11-28 cassette round out the physical drivetrain, which delivers exceptional mechanical precision and consistency, as well as durability, that works so beautifully with the performance requirements of Di2. This is most impressively seen in the stiffness and machining of the large chainring, which must not only withstand the impressive shifting power that enables the Di2 front derailleur execute perfect shifts under any load or chainring combination, but also must run smoothly, quietly, and ensure proper chain retention.

Pinarello uses their MOst brand kit items in this build. See the simple yet comfortable shaping of the Jaguar XA aluminum handlebar, the stiffness and aero properties of the forged aluminum Tiger Aero stem, and the fantastic grip and feel of the synthetic bar tape. The FlatBack aero seatpost is considered part of the frameset, and it carries the popular and versatile fit of the Fizik Antares R7 saddle. A long-term relationship with Fulcrum brings the Prince a 622x17c ERTO Racing 0055 CL Disc Wheelset, which features the smooth ride and performance of steel spokes and stout rim profile that serves the 17mm internal rim width well, as the 700x25 Vittoria Zaffiro Pro tires can easily handle dirt country road transitions and rough pavement found virtually everywhere.

In short, the 2019 Prince Disk Ultegra R8050 Di2 Bicycle essentially has about as balanced a build and specification sheet as possible. For those with strong sense of Pinarello's history, the nameplate will be both welcome and nostalgic, but this is a complete bike that reflects the needs and desires of cyclists today- and tomorrow, and shows how the company truly taps into their experiences with Team Sky and professional cycling to offer premium engineering and design from the Dogma series as well as high-grade materials in a bike that is attainable and eminently rideable by a greater percentage of cyclists today. Combine that with the usual distinctive and detailed Pinarello graphics and finish, and royalty everywhere should take note.
