Zero.6 is the the peak of Wilier Triestina technology: we finally reached the goal to produce a 680 grams painted frame, keeping the handling and stiffness our products are famous for.
It is not so difficult to save 100 grams from a standard frame, but it has been almost impossible to shave that weight from a sub-800 superlight frame, known as Zero.7 . We are talking about 15% of the overall weight.
In these years we tested several types of carbon, using the existing mould of the Zero.7 . We used different kinds of carbon and different ways to “lay-up” the frame. We built and destroyed several samples. After almost two years, finally, we found the way to have a super light weight, resistance, stiffness, perfect handling, all in the same package. The main news is about the new carbon fiber used in combination with trusted 60T and S.E.I. FILM: this fiber is named DIALEAD ™ from Mitsubishi Japan. The DIALEAD™ fibers are produced from a different base called PITCH, which is generally obtained by crude oil or coal: this type of fiber features High Purity and High and Ultra High modulus. Using a different kind of carbon and a different lay-up is not the only secret of the brand new Zero.6. That would be too easy. The complete process had to be renewed: different temperatures and different pressure during molding. This new process adds another point to the long list that makes Zero.6 absolutely exclusive: we needed to open a new mould because we cannot use the Zero7’s mould. It doesn’t matter that the shape is 99% the same. The process needed a new platform to be able to produce such special frame.
Wilier Triestina’s designers know perfectly well that it is the details that make the difference. Little things can make a huge difference. This is why they haven’t neglected any of the details in the new integrated cable system. The plate through which the rear brake cable enters the top tube has been redesigned to permit passage of electronic wires if running an electronic group. This 2-in-1 plate is minimal, almost negligible in weight, and cleanly integrated into the frame. The same applies to the shifter cables (the front and rear derailleur in the mechanical version), which enter through a tiny plate on the down tube. The special internal design of this plate perfectly guides the cables inside the down tube, minimizing friction and keeping the cables tense and perfectly straight up to the point where they cross over in the plate positioned underneath the bottom bracket. The shifter cables cross over outside of the frame on a cable guide plate, making it impossible to direct them the wrong way. When using an electronic group, the plate on the down tube is replaced by a blind plate, giving the frame a cleaner, more elegant look. The shape of the cable routing plate under the bottom bracket is specially designed to cross over the shifter cables with minimum friction and provide the perfect cable angle for the function of either shifter cable. We made sure that the rear derailleur cable is kept suspended inside the chain stays without touching its walls. In the derailleur however, it allows the cable to reach the attachment point to the derailleur at a natural angle. The cable guide plate is flush within the frame, which provides a smooth aerodynamic surface. This improves air flow over models using a traditional plate.
To achieve greater riding stability and aerodynamic efficiency, Wilier Triestina’s technicians have focused their attention and research on the front end of the frame. We found that by repositioning the down tube and the top tube with respect to the head tube, the head tube’s height virtually increases. The resulting virtual increase increases torsional stiffness by 14% over the same size frame in the previous version of the Zero.7. With this new configuration, the down tube seamlessly integrates with the crown of the fork and generates an aerodynamic profile that reduces drag. The fork’s legs boast the same aerodynamic features as the TwinBlade and Cento1AIR models. The fork’s brake hole is hidden by the down tube which keeps it clean and well protected. The resulting new design also gives the front end improved aesthetics with simple, harmonious lines.
No joints, glue or screws: rear dropouts form a single unit with the lower part of the rear triangle. The joining section, usually constructed in aluminum, is also part of the carbon monocoque unit. All of this means gr eater lightness and stiffness.
Wilier looks to every detail on our bikes to optimize performance and functionality, and our 3D Derailleur Hanger is evidence of this. Zero.7 derailleur hangers are no longer merely there to facilitate the installation of the rear derailleur. They have assumed a third dimension of functionality, seamlessly integrating different systems while simultaneously serving as cable stops. For our new 3D Hangers, we dramatically increased stiffness to ensure perfect shifting and improved durability. The new 2-in-1 derailleur hangers can be used with either mechanical or electronic groups. With a mechanical group setup, the cable stop is positioned closer to the derailleur itself. This enables a shorter length of housing from frame to derailleur, while still allowing for optimal cable arc-maximizing rear derailleur smoothness and consistency. As with the Zero.7’s internal cable routing through the down tube, this cable stop keeps the rear derailleur shift cable well-tensioned and centered within the stay for a silent and frictionless shift action. When using electronic groups, the design allows the electric wiring to pass through in the cleanest way possible. The internal electric routing is optimized as well, with the wiring’s point of exit positioned well above the dropout for quick and unencumbered wheel changes.
