Pinarello Dogma 2 Electronic - 2012 $0.00
The Pinarello Dogma 2 Electronic is specifically configured to be used with non-mechanical shifting systems like Shimano Di2 and Campagnolo electronic. The shifting wires are routed internally through pre-configured openings in the frame. And it has a dedicated battery mount on the down tube just below the water bottle mount, so you can throw away the mounting harness and hardware that comes with your battery. Otherwise this frame is identical to the standard version of the Dogma 2 and retains all the asymmetrical shaping of its predecessor, the Dogma Carbon.
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 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 sometimes 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 after the laminate cures. What you'll find on the inside of the Dogma 2 is a smooth finish that nearly matches the outside.
The Pinarello Dogma 2 Electronicc 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 electronic derailleurs (which we have here) and one specifically designed for mechanical systems. This electric Dogma 2 is ready for your electronic shifting systems. It is not compatible with mechanical systems due to a lack of cable routing necessities.
