Paris-Roubaix hopeful Edvald Boasson Hagen (Sky Pro Cycling) set off from Compiègne on Pinarello's classics-specific Dogma K – essentially a rebadged version of the KOBH 60.1 model. Boasson Hagen didn't have the best showing with a 47th place finish but his bike looked ready for the arduous task.

Pinarello took a slightly different approach with its Dogma K, building a frameset that was more narrowly suited for the spring classics than the so-called 'endurance' bikes marketed by a number of other companies. Among the changes from the more road racing-oriented Dogma 65.1 Think 2 are a softer-riding rear end, more tire clearance, and mellower handling for added stability on the cobbles.

Notably absent is the extended head tube normally associated with these sorts of machines and in fact, it's essentially unchanged between the two models. As such, Boasson Hagen is able to easily achieve the same position he would normally run and team mechanics don't have to resort to extreme measures to get there.

As is fairly standard practice for Paris-Roubaix bikes these days, equipment changes from everyday road racing rigs are rather modest. Boasson Hagen's bike was fitted with 27mm-wide FMB Paris-Roubaix tubular tires, the bars were double-wrapped, carbon cages were traded for sturdier aluminum ones, and gearing was changed to taller 53/44T chainrings and an 11-23T cassette to better handle Paris-Roubaix's high speed and flat parcours.

Another recent trend found on Boasson Hagen's Pinarello is the use of carbon wheels. Once thought to be wholly inconceivable for Paris-Roubaix's brutal cobbles, Boasson Hagen wrapped those high-volume tires around Shimano's 50mm-deep Dura-Ace WH-9000-C50-TU carbon tubulars.

Boasson Hagen – and the entire Sky team, for that matter – did go against the tide of Shimano-equipped riders at Paris-Roubaix, however, with his use of a Shimano Dura-Ace Di2 electronic transmission. Sprint shifters were installed on the drops just as he would normally run on his stage race machine, and the rear derailleur was fitted with a Berner carbon fiber cage with larger-diameter pulleys that supposedly decrease drivetrain friction.

Even so, it's all fairly standard stuff here – with the exception of Boasson Hagen's saddle. The fi'zi:k Antares VS normally features a central channel from tip to tail but the company has created a custom version – or five of them, to be more precise – where the rear portion of the channel has been filled in before the cover was installed. This lends a more traditional feel in normal riding conditions but still retains the supposed blood flow benefits when sitting further out on the nose.

Carbon wheels, a fancy electronic transmission, and a custom saddle still can't hide the fact that Boasson Hagen's Pinarello seemed rather heavy, however. Actual weight as pictured was 8.46kg (18.65lb) – 240g heavier than Juan Antonio Flecha's KOBH 60.1 from 2010 despite it having 32-hole Ambrosio aluminum box-section rims and 14/15g double-butted spokes.

Given the high-end kit installed, we can draw no other conclusion than that the Dogma K is substantially heavier than its 950g claimed weight or Boasson Hagen's particular chassis was reinforced with additional carbon layers to boost its stiffness and durability.

Aesthetics are purely personal but I find all the Pinarellos ridden by Sky and Movistar to be so unpleasing to the eye I'm not that interested in checking out the gallery. I appreciate the article, but I just don't dig those bikes. To each their own.

Now that is a boring-as-hell bike and that's with the splash of colour from the norwegian flags...

The new Dogma 65.1 Think 2 is Pinarello's lightest frameset they have every produced and offers the ability to run electronic or mechanical groups all in the same frame.
For 2013 the new Dogma 65.1 Think 2 becomes Pinarello's flagship racing frame. It is built with Toray 65-ton Torayca 65HM1K Nanoalloy carbon, the strongest carbon Toray has ever produced. This gave Pinarello the ability to lighten the frame without compromising ride quality, rigidity or strength.
The second thing Pinarello focused on with the Dogma 65.1 was the integration of both mechanical and electronic groupsets in one frame. A frame like this will definitely see a lot of Campagnolo EPS and Shimano Di2 groups on it but Pinarello also wanted to offer the ability for mechanical groups to go on the same frame. This is where the "Think 2" part of the name comes from. So Pinarello came up with interchangeable cable stops for electronic or mechanical groups which both function and look great. All done with Pinarello's impeccable Italian style.
The Dogma 65.1 will carry over the 1.5-inch bottom headset bearing, the aero integrated downtube and fork junction, the Italian bottom bracket and offer slight refinements to the asymmetric design. Think Asymmetric is Pinarello's tag line and it all started with the Dogma 60.1. The Dogma 2 brought new refinements to the asymmetric design providing now for the third time with the Dogma 65.1 Think 2.

Frame: Carbon 60HM1K Torayca(R)
