Description

Perfectly Pinarello.

Let's face it, the Dogma K8 is the bike most of us should be on. Sure the Dogma F-series gets all the attention under Team Sky during the grand tours, but the K bikes slightly longer wheelbase and increased tire clearance offering more stability and a smoother ride on rougher roads. The race fit and a good chunk of the geo numbers carry over from the F Dogmas, so it has the racing pedigree in fact, the K8 is frameset the pros at Team Sky choose as they tackle the beautiful and often harsh spring cobbled classics and while it does lack the active suspension of the K-S, it's by no means uncomfortable. If you value light weight and clean looks as you tackle gran fondo epics and still want something spirited enough to be competitive on the Tuesday Night World Championships, we can't think of many other bikes we'd rather be on board than the Dogma K8 Ultegra Complete Road Bike.

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 breakaways and well as pushing your own personal limits on the bike. As we alluded to above, the geometry receives some minor tweaks notability a slightly longer wheelbase for a touch more surefootedness when the pace is just above tempo and you're on rarely maintained farm roads. The bike is purpose-built for your own version of the spring classics where you string together roads with the least amount of traffic or any of the new endurance races melding a mostly pavement parcours with some gravel thrown in for good measure.

Pinarello asymmetric design ethos 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 eke out a little more speed with 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.

Compared to the K8-S, the biggest difference 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 motion to help further smooth the ride on the longest, roughest races, and Sky uses this at Roubaix. Not all of our rides are Roubaix-esque so 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. We feel this 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, with Italian threading no less. 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, as we have here, and electronic groupsets if you're changing things out in the future.

This build is no-nonsense with no glitz and glitter. We spec Shimano Ultegra R8000 because it works plain and simple. Reliable and precise shift after shift and powerful braking season in and season out. The same could be said about the Mavic Ksyrium Elite UST Wheelset. We're big fans or road tubeless and before carbon wheels dominated the pro peloton, the Ksyrium was the premium aluminum wheel. Likewise, the Zipp aluminum bar and stem might weigh a few grams more than the carbon offerings but many pros still favor aluminum in these areas because it often fares better in crashes and we feel its good enough for them, it's plenty fine for the rest of us.

K8

  • Familiarity: I've used it several times

This is by far the nicest bike I've ever purchased. I'm coming from a Look 566, which is renown for comfort, but the K8 surpasses it by a surprising margin. Going over the many wood deck bridges in my area the K8 is surprisingly smooth compared to my Look.
Assembling the bike was pretty straight forward. I was surprised that it came setup tubeless. I put those rims on my Look and moved my carbon rims to the K8. I'm also going to upgrade the saddle - the Fizik is going on my rain bike.
Great bike. I commute daily on this bike.

Oh wow!!!!

  • Familiarity: I've used it several times

So I have logged about 100miles so far, but here are my initial impressions. It handles like no bike I have ridden. Not twitchy at all but if you even think it, it is going to go in that direction. What I find amazing is it can "snap" when you get on it and feels beyond stiff but at the same time it handles road vibrations better than any bike I have. I find that hard to reconcile in my mind but it is what it is. It feels almost magical in handling both of those aspects. The longer rides are super comfortable and I am finishing up with no pain in my back or numbness in my right hand like I get from my other bikes. The group set it comes with work great. I swapped out the saddle and the wheels so there is a difference compared to what is spec'd out above which will change the ride obviously. All in all, I am just floored by the ride quality and the performance. I knew it would ride well but I had no clue how well I would jive with it. As an aside competitive cyclist was super helpful and the bike came in perfect condition and packed very well.

Oh wow!!!!
