Wilier Cento1 SR Road Bike Frameset - 2015

The Wilier Cento1 Frameset has been around for a few years now, and, until the SR, it has remained virtually unchanged. That's because it was such an incredible, well-balanced frameset to begin with. The recipe was simple--a tight wheelbase and a comfortable, tapered head tube. The design dictated that the oversized head tube acted as a stabilizer for the somewhat twitchy frame geometry. The head tube made the frame comfortable for the long haul, but the hyperactive frame geometry provided explosive performance during attacks. The SR is a similar frame design, but Wilier has added elements from its other top-shelf frames to make it the most balanced frame in the Wilier stable. The most important, and most noticeable, elements in the new frame are the massive chainstays and the Wilier-developed BB386EVO oversized bottom bracket. Developed in cooperation with FSA, the BB386EVO is 86. 5mm wide and has a diameter of 46mm. Wilier estimates that the new bottom bracket increases rigidity by 30% and reduces power dispersion to almost zero. Additionally, this shell's width provides Wilier with the ability to widen the seat and down tube diameters by around 20mm. Of course, this means increased rigidity, but it also means decreased tubing wall thickness and weight reduction. Altogether, Wilier credits BB386 EVO with increasing overall torsional rigidity by 133% and rear triangle stiffness by around 115%. Also new for the SR is a stiff, multifunctional 3D derailleur hanger, a 3D integrated cable routing plate under the bottom bracket shell, and an integrated adjuster plate for your internal cable routing. Easily the SR's most distinguishing component feature, however, is the Wilier Monocoque integrated fork. The down tube is angled upward, while the top tube accommodates the head tube's downward angle in approach to the new fork. This technology has been proven with the Twin Blade, and it greatly reduces the SR's aerodynamic footprint.
