The 98th Tour de France begins on the 2nd July and Movistar Team will mark the debut of the Dogma2, the evolutionary frame which revolutionized the world of road racing two years ago with its asymmetry concept. As always, the pros will test and take advantage of this new model which will be available to its fans in 2012.
For those who have an eye for detail and study each stage of this race in order to capture each and every detail possible of an object, this will transform into their desire for next season. The Time Trial stages will obviously be assigned to the Graal, which has demonstrated to be futuristic in this extreme race against the clock. The eyes of everybody will be on the guys of Eusebio Unzue and, most of all, of the new Spanish Champion José Joaquin Rojas, who wants to confirm his good shape and he is in search for a great result.
Resume and exaggerate the characteristics of the Dogma, reconciling the rigidity that has decreed its success in aerodynamic resistance: this was the main objective studied in the evolution of the new Dogma, an accomplishment of in-depth research into Computation Fluid Dynamics, achieved with thanks to the exclusive computerized systems of the Pinarello Lab. On this note, many small details of the bike have been revolutionized, several elements of them that make the Dogma2 frame one ‘to copy’ over the next few years-
Starting with the evolution of the Onda FPX Fork, with its reduction in the ribs, which affect the air flow and a rear ‘tail’ which eliminates turbulence in the junction zone. This offers the frame a more regular air flow along the right hand side, compensating for the lateral rigidity, thanks to a new and improved layering of carbon.
The frontal rigidity is also supported by a new series of cone headsets, ranging from 1″ 1/8 – 1″ ¼ to 1” 1/ 8 – 1” ½. In order to accommodate for this new formula, the nose has been increased in size by 6%, but thanks to more effective provision of the ribs in both the horizontal and vertical tubes, which have been joined together, it has been possible to increase the stiffness in braking by 19%, reducing the impact of aerodynamic drag by 10%.
The concept of asymmetry has proven to be successful, and hence there has been an exacerbated amount of effort placed on the top horizontal tube which has been shifted more so to the right (those with an eye for detail may also notice that the rib on the right side is continuous, while that on the left side comes to an end much earlier). A more pronounced asymmetry, which paradoxically leads to an increase in the symmetrical pedal action of 6%.
Important interventions have also occurred in rear section of the frame, where there have been reductions in certain ribs and an increase in the stratification (layering) of the carbon fibre. Careful analysis in regards to the internal distribution of cables, which can always produce an element of “noise” from the aerodynamic point of view, now have their impact reduced by 2%. A removable cable guide has been placed on the bottom bracket, this has been fully integrated into the frame as well as the entry and exit points of the cable. For those who use electronic gearing, a battery holder is attached directly to the frame along with internal cabling to avoid the use of additional clamps.
These modifications result to dramatic differences in the Dogma2: despite an increase in the weight of several sections in the raw frame, the Size 54 is reduced to the extent of 30g compared to the previous Dogma 60.1, hence taking the frame just on 920g. Meanwhile the aerodynamic impact of the frontal area (fork and head tube) of the Dogma2 frame has been reduced by 6% compared to the same area on the Dogma 60.1 frame.
