As shown above in the highly complicated design, Pinarello has challenged what conventional setups are all about, all in the name of efficiency. They have approached this newest XC platform by employing highly complicated asymmetric engineering principles that are now world renown, and proven themselves time and again by the world’s most demanding riders out there. The Italian manufacturer’s new Pinarello Dogma XC 9.9 mtb stands in there as their highly skilled flagship cross-country frameset, it utilizes numerous high tech qualities, such as advanced tube shaping, a very complicated carbon layup design, along with a highly innovative thought process that places the crafty engineers well ahead of all the wolves in the pack. To ultimately put you on top of the podium, where you rightfully belong! The key materials that were selected to construct the fabulous Dogma XC ride, are actually quite similar to what their top-end road frames are all about. Which utilize proprietary material that comes straight from the Japanese carbon fiber supplier known as Torayca. It’s a 60-ton 60HM1K Nano-alloy Carbon Fiber that’s makes things amazingly rigid and highly reactive both at the same time. As denoted by it’s name it’s fully capable of withstanding the full 60-tons worth of peak pressure for one square centimeter. Because the material supplies such a high level in the rigidity department the Pinarello designers were able to capitalize and use less of it in many of the key areas, which then helps to reduce the overall weight for this pure bred XC racing machine. For additional safety, Torayca designed the 60HM1K Nano-alloy technology with a perfect mixture of alloy nano-particles that actually get embedded right into the carbon weave itself. So through extensive testing they determined that these particles actually “explode” upon significant impact. Which allows, the particles to absorb the kinetic energy of any impact forces so that the carbon itself doesn’t have to. For both the tube junction areas and the tube shaping on the race-bred Dogma XC were given very careful and thought out design consideration by Pinarello’s extensive team of engineers in regards to bump compliance and higher pedaling efficiency. Knowing that rigidity and power transfer are the key words when it comes to the down tube and chainstays, they constructed these with massive, oversized tube shapes. The bottom bracket that joins them was built using a PressFit 30 system, with the seat tube flaring out to the full shell width on the non-drive side. This design provides a rock-solid pedaling platform that directs your efforts straight to the rear wheel. Above this junction, Pinarello added an integrated front derailleur mount on the asymmetric seat tube, allowing for either SRAM or Shimano to be seamlessly routed. For the head and down tube junction, take notice of Pinarello’s “ForkStopper” technology integrated into the frame. It has a purpose, as many frames are constructed with raised down tubes to limit contact with forks, the Dogma XC uses Pinarello’s PinaFit XX9 geometry. This design allows for a smoother, uncompromised downtube angle, which translates into better stability by using the correct geometry over other variables such as fork rotation. The ForkStopper allows Pinarello to use this geometry and also to address the issue of fork impact in the event of a crash. At the rear triangle, the slender seat stays wear a shape reminiscent of its pavement-devouring Dogma cousins, but the sloping tubes come together up top as an integrated seat post clamp assembly above the top tube. Pinarello separated the seatstays both vertically and laterally into its “ONDA XC Asymmetric Twin Arms,” dissipating vibrations in a uniform way and across a large surface area. Its engineers wanted to address both stability and comfort with this design, which is why it carefully examined the way traditional hardtail frames were designed. A typical frame joins the seatstays, seat tube, and toptube at the same spot, which sends vibrations and impacts from the rear wheel straight to the top tube. By dividing the frame into two separate triangles — and moving the seatstays slightly higher than the top tube — shock transfer to the front of the frame is eliminated. The seatpost clamp itself is dubbed X Power, which allows the four-bolt clamp to securely hold the seatpost by joining the seatstays over the top tube. According to Pinarello, this reduced the stress in this clamping area by 50%, making a more effective setup. Several key features found are the extremely clean cable system that are internally routed along with a very innovative rear brake mounting setup. Pinarello went the route of mounting the brake caliper to the chainstay, rather than on the traditional seat stay area. This Rear-Arm Disk (RAD) design allows the seat stays to maintain higher levels of bump compliance, that are uninterrupted by the braking process. Also, the big non-drive chainstay tube provides a stronger overall braking platform, resulting in highly-responsive, powerful braking out back. The Pinarello XC 9.9 sizing is available from Small all the way up through X-Large, while the color is Matte Carbon.
