Pinarello RoKH Ultegra Di2 2012

The ROKH (pronounced 'rock'), which was developed for racing on the extreme roads of northern Europe such as those traversed in the Tour of Flanders and Paris-Roubaix, features Pinarello's new Century Ride geometry, first developed for the KOBH.

The compact chainset, with a wide range of sprockets on the cassette, gives you a large choice of gears for speed and for climbing. Many sportives events incorporate some nasty/steep climbs on the route so having a compact chainset makes life a little bit easier.

The sloping geometry offers a slightly greater stack height for a given reach, which 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 lateral stiffness. The ROKH shares the asymmetric frameset design that compensates for the uneven forces acting on the frame due to the drive train being offset to the right side. The ROKH also features Pinarello's proprietary headset system, but for the first time the lower bearing has been increased to 1 1/2" allowing an additional taper to the steer tube further increasing front-end rigidity for more precise handling and stability during quick maneuvers such as sprinting or fast twisting descents.
