Apr 2, 2015 – The new frame is derived from the highly successful Dogma F8 and the Dogma K. The Dogma K8-S continues the collaboration between Pinarello, Team Sky and Jaguar Land Rover. The K8-S borrows the aerodynamic FlatBack tube shapes from the F8 and introduces a suspension element to tackle the pavé.

The K8-S was first introduced to Team Sky in January, with Sir Bradley Wiggins and others riding reconnaissance on the last 130 km of the Paris-Roubaix course. After the Arenberg Forest Sir Bradley shares his feedback with the team car: “This is a Game Changer!”

Suspension, the word immediately evokes “more weight”, this in fact was the first challenge: create a suspended road bike frame under one kilo. The Dogma K8-S frame set weighs in at an amazing 990 grams including suspension.

The Dogma K8-S’s chainstays are designed to allow almost 10 mm of vertical deflection, and, at the same time, guarantee enough torsional stiffness of the rear triangle for ideal power transfer.

To reduce the flexural inertia vertically, we reduced the height of the cross sections, and to increase the lateral stiffness and contain the loss of torsional stiffness due to the reduced height, their width was decreased.
