Inspired by Gran Fondo events, the Pinarello Dogma K Hydro Road Frameset is identical to the Dogma K frameset, except for the addition of disc brake technology for unmatched stopping power in all conditions. Although it suffers a minor weight penalty over the non disc Dogma K in this case, roughly 150 grams, it benefits from greater stopping power, especially when the conditions take a turn for the worse. If you're not familiar with the Dogma K frameset, it's essentially an endurance oriented version of the Tour de France dominating Dogma 65. 1 frameset, with the same Japanese sourced Torayca 65HM1K carbon fiber and electronicmechanical cable routing that makes the Dogma 65. 1 an ideal choice for racers and pro cyclists. However, where the Dogma K Hydro and Dogma K as well differ lies within its more forgiving ride, courtesy of a more relaxed head tube angle and lengthened chainstays. And like most endurance bikes, it can easily accommodate wider tires without any clearance issues whatsoever. You'll notice the striking asymmetrical design of the Dogma K Hydro frameset, which is beneficial in leveling the differences in frame deflection from one side to another. Other cool features include a 1. 5 inch lower headset bearing for increased front end stiffness for a more predictable steering feel, as well as a redesigned Onda HD fork that's made to handle the stresses of disc brakes. And to handle the braking on the rear end, Pinarello mounted the disc caliper at the chainstay rather than the seatstay location that most manufacturers use.
