Review by Grant
I had been intrigued by the Pinarello Dogma K8-S since its release, but had always deemed it a bike most suited to cobbled or rough surfaces. As little of my road cycling involves this, I never thought that the K8-S would be anything more than another interesting frame design to be admired.
Reading a couple of magazine reviews had sustained my interest in the Dogma K8-S, so when the chance arose to ride one, it seemed to be too good an opportunity to miss.
Before heading out on a ride, l was keen to learn a little more about the K8-S. Being able to look at the bike up close, it was possible to pick out some of the subtle design details that Pinarello had included.
The Dogma K8-S is formed from the same 1100k high modulus carbon that is used for the F8. The K8-S frame design incorporates a specific shaping into the carbon fibre stays, to enable a greater degree of directional flexibility than that of a conventional rear triangle. These work in conjunction with an elastomer shock located behind the seat tube. The shock can be made more or less firm by adjusting a dial that forms part of its outer case. I understand that this adjustment can be carried out using a specific tool, supplied by Pinarello.
The seat post of both the Dogma K8-S and F8 are secured in position via 2.5mm Allen bolts at the rear of the seat tube. The K8-S incorporates three of these, the F8 has two. This subtle detail is in keeping with how the K8-S allows the rider to remain seated and pedal through cobbled or rough surfaces.
