Those who own a Wilier know that they didn’t choose just any bike. They know that the symbol of the halberd is part of the history of cycling,and a history more than a century old.

There are lots of suspension systems available to frameset makers on the full suspension market. There are simple systems and very complex ones, and each has its pros and cons. It’s not easy to choose among the many different systems available, unless you know what you’re doing. The idea Wilier Triestina’s engineers had in mind when...

The story of Wilier Triestina

Technologies

IF integrated fork

The handling of a Wilier bike is one of its most treasured attributes. We continually search for ways to further improve the solid feel at the front end, which has led to some of the most significant of the Cento1 SR’s enhancements. We found that a new way of positioning the down tube and top tube with respect to the head tube creates a virtual increase of the head tube’s height, which makes it 14% stiffer in terms of torsional rigidity. The top tube approaches the head tube at a downward angle while the down tube is angled upwards as it joins the head tube and the Integrated Fork. This junction is traditionally like the point of a triangle, but this new angle and positioning makes it more like a square, which is stiffer. The back of the fork’s brake hole is tucked into the down tube, keeping it clean and protected from the elements. The Integrated Fork design also creates an aerodynamic profile that reduces drag. Drawing from research implemented in development of our Twin Blade, the Cento1 SR’s fork legs are designed for optimal stability and aerodynamics. Like the proven Kamm truncated tail concept implemented in our time trial models, both the Cento1 SR’s integrated seatmast and fork legs benefit from this structural innovation, thereby attaining a perfect balance of lightweight, aerodynamics and steerability.

asymmetric rear arms

Wilier road bikes are famous for their front ends. Our integrated head tube and fork designs equate to unrivaled steerability for confident cornering and descending. The oversized, squared profile that characterizes our fork crowns and that flows into the base of our head tubes maximizes strength and stability at a key fulcrum point.

Integrated seatpost concept

We believe that a bicycle targeted to professionals should offer the best performances from every standpoint. An integrated seatpost allows the frame to achieve these peak performances, by supplying an ideal balance of mechanical operations, weight and comfort. Cento1 SR’s new integrated seatpost also offers improved aerodynamics thanks to the special truncated tail design.

LIT

We’ve also leveraged LIT (Large Inflation Tube) technology in the making of the Cento1 Superleggera. Our prepreg carbons benefit from even higher and more uniform compaction through the use of industrial, high pressure bladders. The bladders expand from within the frame’s tubing, pushing against the inner walls of the tubes as the frame mould exerts opposing pressure from the outside. The combined compaction- forces result in a precision, lower-void construction and consistent wall thickness of the tubes throughout the frame’s construction. More traditional carbon manufacturing processes fail to optimally compact a composite, resulting in varied wall thicknesses, or voids (undesirable resin deposits), along a frame’s tubing that compromise structural integrity. That could translate into reduced longevity and strength. So the advantages of the Cento1 SL’s construction are obvious: increased capacity to handle stresses, optimal torsional stiffness, and unparalleled responsiveness.

FSS

Floating Suspension System

In this system the shock absorber is not anchored directly onto the frame at a certain point, but floats between two links connecting the rear stays. This unusual design boosts pedal power (and therefore effectiveness when riding uphill) because it gives the bike a low bobbing level and a low pedal kick back. The perfect system for what we wanted to achieve! The utmost efficacy riding downhill and high pedal yield riding uphill, in or out of the saddle.

Technologies

SEI special elastic infiltra

Zero.7 marks the implementation of an exclusive new Wilier Triestina technology: S.E.I. Film (Special Elastic Infiltrated). The injection of a proprietary viscoelastic film between layers of carbon increases vibration absorption and impact resistance, therefore making the frame safer and more comfortable. This new material has already been widely tested in the aeronautical and automotive industries with excellent results. It is now being applied in the construction of bicycles for the first time.
