Pinarello ROKH Ultegra Di2 Road Bike - 2012
The Pinarello ROKH (pronounced "rock") is a direct descendent of the KOBH which was developed for racing on the extreme roads of northern Europe such as those traversed in the Tour of Flanders and Paris-Roubaix. As with the entire Pinarello range it features a new asymmetric monocoque frame, making it powerful and highly rigid. The asymmetry helps balance the offset power delivery due to the drivetrain being offset to the right. The stiffness is most noticeable during hard efforts when sprinting or climbing, but it's always working to keep the bike balanced and the wheels planted.
The ROKH features Pinarello's new Century Ride geometry, first developed in the KOBH. The sloping geometry offers a slightly greater stack height for a given reach. This is accomplished by increasing the fork length and rake slightly to raise the front end and changing the rear triangle from the Onda System to the Century Ride System. The Century Ride System incorporates curvilinear seatstays which increase vertical compliance without sacrificing stiffness.
Far from becoming a luxurious touring machine, the ROKH still showcases the ride characteristics that sets Pinarello apart while increasing the comfort and versatility on longer cycling excursions.
The steerer tube of the fork now tapers from 1-1/8" to 1-1/2" to create an even stiffer front end for precise handling, especially when the road gets fast and twisty.
Changing gears becomes easier, effortless and faster by simply touching the shift buttons. With the added benefits of an automatically trimming front derailleur, great accuracy plus easy installation and adjustment.
