Details

This is Pinarello’s WorldTour-level endurance, fondo, cobble cruiser frameset. The name tells a good part of the story: Pinarello Dogma K8-S Frameset. It’s a Pinarello, one of the most storied names in modern racing. Dogma: a top-of-the-line frameset. K=Kobh=cobblestone. 8 is from F8, their road racing bike. S stands for shock. Yes. This bike has an actual shock. Dogma Suspension System 1.0 (DSS1.0): an adjustable, elastomer rear shock. It provides 10mm of travel. It sits between the seatstays and the seat tube. Thanks to their manipulation of carbon-fiber, there is no pivot on the chainstays. To further the rough road-worthiness of the rig, the bike comes with a direct-mount rear brake. The direct-mount design affords more room for big tires, like up to 29mm wide depending on the brand and the rim.

Stepping back from the rear triangle, it might be hard to tell that this bike is the rough road rig of the Pinarello line. That’s a result of borrowing many of the design features of the F8. The K8-S has the aero head tube, the FlatBack tube profiles, the aero seat post, the same bowed fork legs. So much is the same that you might be wondering if it’s the same frame.

It isn’t. The geometry has been tweaked more than adjusted. Portions of a degree slacker in head angle. The fork is 6mm longer. The fork rake is 4mm greater. The chainstays are up to 1cm longer. The seat angle and top tube remain the same. The benefit to all this is a bike that has the comfort of a pave pounder, but the feel of a traditional road racing bike. It’s a heady combination: allowing you to ride faster over the rough stuff, and have more energy for riding fast-and enjoying the benefits of a race bike.

As with most Pinarellos, this frame comes with an aero carbon-fiber seatpost. It’s 300mm long and can house an electronic-shifting battery. The bottom bracket is Italian-threaded. The headset is included, internal, and a tapered 1 1/8” to 1 1/2”. Cable routing is internal. They also run their 3XAir cage bolt system on the K8-S. Use the lower two for better aerodynamics and weight distribution, the upper two for convenience. Cable routing is internal. Dropouts are carbon.
