Comfort and Speed.
Pinarello has a rich history in the cycling world, and, over the years, has worked with the sport's best riders. This connection to the highest level of the sport has garnered valuable feedback for the brand and pushes it to construct framesets to cope with unique courses and conditions. The Dogma K8 Road Frameset is Pinarello's answer for the pros at Team Sky when tackling the harsh and beautiful cobbled classics. While it does lack the suspension of the K-S, comfort is still the name of the game, and if you're looking for a lightweight steed to crush your next gran fondo epic, we can't think of many other frames we'd rather be on board.
The same Torayca T1100 1K Nano-alloy composite used on the Dogma F8 is called on for construction duties on the K8. This guarantees lightweight performance with the ability to gobble up pavé and chip seal imperfections, helping you stay fresh in the breakaway. Also helping to improve ride comfort and handling while on the rivet, chewing stem, and trading out pull for pull, the geometry receives some tweaks. Most notable of these is a slightly longer wheelbase and a headtube that has grown a smidge for a touch more stability when the pace is à bloc over bumpy secteurs. This frameset is almost purpose-built for events like the Roubaix sportive, cobbled waffle rides, or Battenkill.
Pinarello asymmetric design philosophy carries over to the K8, so areas of the frame that are on the sharp end of wattage transfer are beefed up to handle the forces while other areas see a reduction in material, saving weight and smoothing out the ride. The frame's stiffness is very much on par with the Tour-winning Dogma F8, and—since it's a race bike, after all—the K8 also gets the same aerodynamic details, including the FlatBack shaping on the down tube, seat tube, and seat stays. These wind-cheating elements let you get more speed out of less effort, and you can keep a little bit more energy in reserve for a late race attack or to contest the small group finishes that so often define races like the cobbled classics.
The biggest difference between the K8 and the K8-S is the lack of a damper at the seatstay junction. The K8 uses the tried-and-true monostay that Pinarello frames have long used, while on the S you’re getting 10mm of cushion to help smooth the ride even more during the longest, roughest races. Unless you're looking for maximum comfort or your roads are exceptionally pockmarked, we'd reach for the non-S; it's a good bit lighter, and Pinarello claims it's more responsive too. This claim makes sense, as there's no chance of losing watts to suspension squish or the added potential of flex with additional joints.
Another K8 feature that's prevalent on other Pinarello's is the threaded bottom bracket, in Italian threading of course. Threaded bottom brackets are much easier to maintain and install, and they virtually eliminate the dreaded creaking and popping associated with press-fit options. The tapered 1-1/2 to 1-1/8 head tube anchors your efforts while sprinting in the drops or during out of the saddle climbing on the hoods and offers razor-sharp tracking on the chase back down. Internal cable routing aids in the aerodynamics department and keeps the frame's lines looking clean. The routing is compatible with all mechanical and electronic groupsets if you're transferring parts or doing a dream build.
