For the Dogma 65. 1 Think2, Pinarello uses a Japanese carbon that's more rigid and reactive than anything it has ever used on a bike frame Torayca's all new 65 ton 65HM1K Nano alloy Carbon Fiber. The improved rigidity allows Pinarello to save weight, by using less carbon fiber in key areas. With this new cloth, Pinerallo hones the asymmetrical shaping of the Dogma bloodline to create a bike that is stiffer, lighter, and even more responsive than its predecessor. One big change is in the Dogma 65. 1's top tube, which has been moved slightly off center toward the right ride of the bike. FEA finite element analysis confirmed that this asymmetrical design was beneficial in leveling the variances in frame deflection from one side to the other. Pinarello also improved the aerodynamics and stiffness of the Dogma's front end. The headset bearing has been lowered 1. 5 inch which gives the Dogma 65. 1 a larger diameter steerer tube at the fork crown. This increases stiffness in the front by roughly 19% and results in a more precise steering feel and predictable braking. The 65. 1 also features more aerodynamic fork legs and a sculpted crown that integrates seamlessly into the reshaped down tube. Furthermore, the Dogma 65. 1 Think2 offers internal cable routing for both mechanical and electronic groupsets, without any penalty to the bike's aesthetic or its aerodynamic profile. This is done with interchangeable cable stops at the frame openings that are capable of being swapped out should you prefer SRAM Red for one season, then Campagnolo Super Record EPS the next. The Pinarello Dogma 65. 1 Think2 Road Bike Frame comes standard with the road dampening Onda 2 asymmetrical carbon fiber fork, a Pinarello integrated 1 18 to 1. 5in press in headset, and a Dogma 2 carbon fiber seatpost. It requires an Italian bottom bracket and a braze on front derailleur.
