The Road Cycling company Pinarello has confirmed they are jumping into the world of mountain bikes with the unveil of their first Twenty Niner, the Dogma XC 9.9.
Pinarello decided they couldn’t find innovation in the twenty niner hardtail and decided to enter the mountain bike market with what they are calling a “striking example of innovation”.
This innovation is the ONDA Asymmetric Twin Arms, the company’s very unique rear triangle. The seat stays attach to the seat tube at different points above the top tube. This dissipates vibrations across the larger surface area, allowing the frame to be a “comfort without rival in a hardtail twenty niner mountain bike without losing any pedal response.”
Another design they 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 XC frame 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 reduce the grams on the scale more, and the area they’re focusing on is with the resin. When building a 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, it allows the resin to have an improved strength-to-weight ratio.
A few other ideas they used on the XC 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 Pinarello 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.
