2021 Pinarello Prince Disk Ultegra Di2 Bike
With all the WorldTour success that the Pinarello Dogma has found over the years, it has perhaps had the knock-on effect of over-shadowing the very excellent Pinarello Prince Disk. Though the Dogma F12 is indeed the flagship racing model in the Pinarello lineup, that doesn’t mean it’s the only racing bike they make.
In fact Pinarello designers have spent a lot of time and research on the Prince Disk to make it super high performance but with a softer edge than the Dogma F12. It takes tons of design cues and inspiration from the Dogma of course. But it steps away from some of the more race-aggressive aspects in order to favor something more universally comfortable. The first major update comes in the shape of the geometry table. The Prince Disk is intended to be the type of racing bike that will be comfortable for a wide range of body types and flexibilities. In order to fit comfortably on a Dogma F12, you basically need to be pretty flexible and even then, you need to be more worried about squeezing every ounce of power out of every pedal stroke, sometimes in lieu of having a comfy ride. The Prince Disk, on the other hand, is meant for those of us who don’t have personal trainers and soigneurs.
They took a look at their nine sizes and reevaluated the reach and stack, slightly shortening the former and raising the latter. Then they made some serious choices about the fork rake for each size. The three smaller sizes have a bigger rake than the others (52mm instead of 47mm). That way they have kept the trail consistent across all sizes, ensuring the same reliable handling. Each size has also been given size-specific tubing, so the larger sizes have tube layups designed to take stronger forces, while smaller sizes can use less material, saving weight and optimizing the ride quality. And for those tubes turns to T700 carbon fiber with a high quality special resin. It is a quality carbon that keeps the frame light, responsive and comfortable without costing an arm and a leg. And the layup has been designed to give each size the same lateral stiffness of the F12 but with greater comfort.
As with every Pinarello, the Prince Disk’s frame has an Asymmetric shape to the tubing. They give the drivetrain side a sturdier layup to help it deal with the greater stresses it will have to withstand. But it’s way more complicated than it sounds since they also have to take the disc brakes into account. That means that they have to have the rotor-side chainstay and fork leg shaped and laid-up differently to accommodate the braking forces. The tube shapes certainly also edge in the aero direction, taking all the best ideas from the F12. Particularly recognizing that on a frame, the biggest penalty is paid on account of the bulge of the water bottles. So not only does the downtube have the same concave section to hide the bottle that the F12 has, but the seat tube bottle position has been lowered 5mm so that it too could benefit from reduced surface exposure. That combined with the Flatback tube profiles, the slick head tube/down tube interface, and the Fork Flaps on the fork make the Prince Disk an elegantly aero racing bike.
Recognizing and accepting the trend toward wider tires, Pinarello has opened up the frame so that it can officially take up to 28mm tires. Then design mainstays like the internal cable routing, the E-Link for electronic groupsets, and Italian thread bottom bracket make the Pinarello Prince Disk among the most lust worthy affordable high performance bikes on the market.
