The new bike Wilier Granturismo fits into the trend of bike racing is not extreme medium-high. He then placed under the Superleggera 101 and 101, with the intent to give up a little tiffness for much comfort over long distances. The new monocoque frame incorporates many of the technical concepts on other models Wilier. The monocoque fork has straight stems, seeds and characterized by a rib reinforcement that creates an edge that characterizes its appearance. The same edge, which function to stiffen the frame tubes, we find him in the top tube and oblique; starts from the head tube and reaches the bottom bracket and the rear. The junction between the tube vertically, horizontally and is well-proportioned rear. The vertical tube remains high for a solution somewhere between a traditional and an integrated seat post. The rear retains the asymmetrical monocoque construction, in which all the cart is made from a single mold and not in two parts then glued together. The cables run inside. The bottom bracket keeps the classic standardized BSA, while not yet declared the weight of the fork and frame, as well as the type of carbon used for its realization.

The frame was placed attention to have a good vertical flexibility necessary for comfort, and good torsional rigidity necessary for the transfer of power. Was pompously declared that the first does not affect the second. This statement is true in part because even the vertical stiffness nevertheless contributes to the transfer of power and therefore reducing the rigidity is nevertheless a small loss in performance.

What is happening on all the frames of the category, compared to their high-range models. The difference is the mix that makes you choose between torsional rigidity and flexibility, vertical, going to establish the character of the bike, which may be more or less comfortable and more or less reactive. Another element is the type of carbon that is used, with stiffness and flexibility, higher or lower. This combination of factors, mixed together, leading to a more comfortable bike over long distances, although slightly less performance than other models that link all about rigidity.

As important and influential on the final performance is the frame weight and quality of assembly. Assembled with SRAM Force group and Fulcrum Racing 3, should be priced around 2900 Euro. Remains to be seen in detail the other components (which can affect, and very, final value), but the cost seems in line with major competitors in the industry.
