Pinarello has designed their newest road bike specifically for the Tour of Flanders and Paris-Roubaix. The new frameset is called the Dogma K8-S. Bradley Wiggins helped Pinarello with the development of the bike, and he has some interesting things to say about it.
“I did testing on it through the winter, the prototype, doing the recons for Roubaix on it,” he said, insisting that it was more than just hype. “The different is unbelievable. It is really hard to describe until you are actually on those cobbles at 50, 60 kilometres per hour, hitting Arenberg at full tilt…[feeling] the vibration that goes through the bike.
The Dogma K8-S features an integrated suspension system, named the DSS 1.0 (Dogma Suspension System). This suspension system works in conjunction with flexible flat carbon chain stays (Pinarello calls them Flexstays). The frame weighs in at 990 grams.
The company is making big claims about the bike, saying it could reshape the world of road racing (like we haven't heard that one before). They say the Dogma K8-S only absorbs the necessary shock of the road, thus allowing you to keep pedaling regularly with optimum power and precision.
So what? Seatstay suspension systems are nothing new. Trek used a frame called the "Pilot" was used back in 2005. The technology was dubbed the SPA or Suspension Performance Advantage. It was a simple elastomer spring in the chain stays that allowed up to 13mm of travel. The tech was said to reduce road shock and provided increased traction for more efficient transfer of power. George Hincapie and others in team Discovery were on these bikes for Paris Roubaix in 2006 where Hincapie was a favorite. Unfortunately his headtube snapped and he wasn't able to take a victory.
Time will tell if Pinarello's new framset is a design that will take off or fail.
