Pinarello Dogma 2 - 2012
At the same moment in the 2011 Tour de France when Thomas Voeckler veered from the tarmac into a vacant driveway near the bottom of the descent into Pinerolo, Edvald Boasson Hagen joyously threw up his hands in victory. It was a redemptive stage for Team Sky as their early tour hopes were shattered when team leader Bradley Wiggins DNF'd after breaking his collarbone and Juan Antonio Flecha lost his chance for a possible stage win after being side-swiped by a France 2/3 TV car. Boasson Hagen's win was notable for one additional reason: It was the first professional win for the Dogma 2 earned after Pinarello officially unveiled it to the world. (The irony, of course, is that the Dogma 2 was ridden to two stage victories in the 2011 Tour prior to Pinarello's introduction. What is it they say about the best laid plans?)
The Dogma 2 retains all the asymmetrical shaping of its predecessor. In fact, Pinarello pushes the envelope a bit farther with the Dogma 2 to create the most responsive Pinarello race bike ever. In comparison to the Dogma it's stiffer, lighter, and more aerodynamic.
During the two years in which the original Dogma sat atop the Pinarello family of frames, the company studied and restudied the forces in action as a rider sprints on the pedals, pulls on the handlebars, and muscles the bike through corners. FEA (finite element analysis) confirmed that the Dogma's asymmetrical design was beneficial in leveling the variances in frame deflection from one side to the other. However, Pinarello knew that they could take the asymmetry to new levels with the Dogma 2. One big change is in the top tube of the Dogma 2. It's been moved slightly off-center towards the right side of the bike to further this effort towards equilibrium.
In addition to this, Pinarello addressed another area for potential improvement -- the aerodynamics and stiffness of the front end of the bike. The Dogma 2 gets an upgrade to a 1.5" lower headset bearing. This allows a larger diameter steerer tube at the fork crown. The resulting benefit for you is a 19% boost in front end stiffness to give you more predictable braking and a more precise steering feel. Another part of the fork re-design includes smoother, more aero fork legs and a sculpted crown that integrates seamlessly into the re-shaped down tube. The Dogma 2 also loses most of the curvaceous ribbing that swept around the tube junctures on the front triangle and stays of the Dogma. All of the cables are now routed internally as well. These changes make for a 6% improvement in the aerodynamic efficiency of the frame.
With this much attention to the asymmetrical design aspects of the Dogma 2, you could easily overlook it from a distance. Only when you're close enough to touch it will you really be able to discern the subtle differences. The left and right sides of the bike bear different tube shapes as well as general section sizes. You can see these differences in the top tube, the fork legs, and both seatstays and chainstays.
The Dogma 2 relies on the same advanced carbon fiber that is used in the dogma. It's called 60HM1K -- meaning that it's built to withstand 60 tons per square cm, the strongest-ever carbon seen on a Pinarello. This material is manufactured by Torayca -- the Japanese composites behemoth with whom Pinarello has had a long collaboration. Stronger carbon, of course, allows for the use of less material as a whole, which results in the weight savings of the Dogma over the Prince. With the refinement of the design, the Dogma 2 saves 30 grams over its predecessor.
One added bonus exclusive to 60HM1K is Torayca's Nanoalloy technology. Alloy nano-particles are embedded into the carbon itself. Upon significant impact (i.e. a final turn crash at the State Crit Championship), these particles "explode" -- in other words, they absorb the kinetic energy of impact forces so the carbon itself won't have to. According to Pinarello testing, the net result is that the Dogma 2 is 23% more impact-resistant than the Prince Carbon. Less weight hand-in-hand with added durability is a rare combination, but it's one provided by the Dogma 2.
The other advancement of note is the actual manufacturing process used for the Dogma 2. Pinarello employs a polystyrene form as a base for the initial lay-up of material during its construction. This enables a more precise method; each layer is placed exactly where it's designed to be according to the FEA testing. In this regard, it's a more reliable and consistent method than molding with an internal bladder. The use of polystyrene also results in even compaction of the laminate, with less wrinkling of the carbon material or trapped gas/resin that could cause structural weak spots over time. The form is removed with a recoverable solvent. What you'll find on the inside of the Dogma 2 is a smooth finish that nearly matches the outside.
The Pinarello Dogma 2 is available in 12 sizes in a wide array of colors. The frame comes standard with an Onda 2 asymetrical carbon fiber fork, a Pinarello integrated 1-1/8" to 1.5" headset, and a Dogma 2 carbon fiber seatpost. It requires an Italian bottom bracket and a braze-on front derailleur. One detail of interest is that the head tube on all sizes is 5mm taller than a comparable Dogma Carbon. Please Note: the Dogma 2 is built in two distinct versions -- one for mechanical derailleurs (which we have here) and one specifically designed for electronic systems. This mechanical Dogma 2 is ready for your standard cable-operated shifting systems. Of course it can be used with electronic systems as well, although it won't be configured for internal wire routing.
- Upgraded 1.5in lower headset bearing for a larger diameter steerer tube at the fork crown for excellent braking and unmatched steering
- Internally routed cables cut wind resistance and add a clean look to an already beautiful bike
