The Road Cycling company Pinarello has confirmed they are jumping into the world of cross country mountain bikes with the unveil of their first Twenty Niner, dubbed the Dogma 9.9 hardtail.
It was decided they couldn’t find innovation in the twenty niner hardtail and decided to enter the mountain bike market with what they are calling the 9.9 “a striking example of innovation”.
This highly creative innovation from the stylists based out of Italy is called the ONDA Asymmetric Twin Arms, which makes for a very unique rear triangle. The seat stays attach to the seat tube at different points above the top tube. This dissipates vibrations across a larger surface area, allowing the Pinarello frame to be a “comfort without rival in a hard tail twenty niner mountain bike without losing any pedal response.”
Another design the engineers are using is the mounting of the rear disc brake inside the rear triangle. We know of a few other models of twenty niner mountain bikes that are doing this as well.
The all-carbon Dogma setup is using 60HM1K by Torayca with Nanoalloy technology. There seems to be more use of nano technology in carbon to make refinements to the setup designs and help reduce the grams on the scale more, and the area they’re focusing on is with the resin. When building the 9.9 carbon fiber setup, the resin is the bonding agent to stick the carbon fibers together. The resin coats each layer of carbon and there can’t be any gaps to ensure structural integrity. By using a resin enhanced with carbon nanotubes on the 9.9 specifically, it allows the resin to have an improved strength-to-weight ratio.
A few other ideas they used on the Dogma XC 9.9 cross country ride are a four-bolt seat clamp that directly mounts to the seat stays. Fork-Stopper technology keeps the down tube from getting bashed up in crashes, as they didn’t curve the down tube for fork clearance to keep their geometry correct, so the Fork-stopper then protects this issue. All hitting the scales at 1,050 grams for the size medium version.
Internally routed Cables, and an integrated front derailleur mount allows for two options of cable routing to suit SRAM or Shimano group sets.
