Wilier Triestina is on the leading edge of the next revolution in road cycling: disc brakes. The Cento1SR Disc doesn't merely incorporate this technology, though. The world famous Cento1 platform is reinterpreted to take the highest advantage of all disc brakes have to offer. For a complete integration of hydraulic technology, Wilier Triestina completely redesigned the fork and rear triangle to accommodate the new braking system in the best way possible.
Combined with the already storied geometry and carbon technology from the Cento1SR platform, the Cento1SR Disc represents the pinnacle of technological innovation, pushing the limits of what was only dreamed of a short time ago.

 


FORK


The integrated fork is characterized by the non-traditional symmetry of the fork legs’ design. Asymmetry is no longer just for the rear triangle. The well known feature of the Cento1 now extends to the fork as well.
The legs feature two different design styles. The right fork leg takes on the truncated tail aerodynamic shape found on Cento1SR. The left fork leg is totally different. Heftier than the right one, and preserving a streamlined profile, it slopes slightly inward to counteract the forces that are produced when braking.
Such an asymmetric fork allows us to balance the forces produced by braking while preserving the sense of stability supplied by a conventional braking system.

 


REAR STAYS


While the main triangle has not changed compared to the SR’s traditional version (we have only added a hole to route hydraulic cable), the rear triangle is completely updated.
With a 135mm width and the post mount housed within the stay, the rear triangle is still asymmetric and closely resembles the 101XN.
The rear hydraulic cable runs initially inside the frame, then into the left stay, to finally exit further down near the seatstay.

 


BB386EVO BOTTOM BRACKET


The BB386EVO system takes the oversized bottom bracket design concept, which was successfully introduced by Wilier Triestina in the original Cento1 model and subsequent variations, to its next evolution. To obtain an unprecedented stiffness at a crucial point of the frame, we have devised an innovative system that can perfectly incorporate an ultra-stiff crank into an ultra-stiff frame. The traditional BB30 system proved inadequate because it requires a frame with a 68 mm box, which is too narrow to deliver the degree of stiffness that we wanted. With this in mind, we developed the new standard BB386EVO in collaboration with FSA, which pairs a carbon crank with a longer 30 mm spindle and a wider 86.5 mm bottom bracket area on the frame. BB386EVO confers stiffness to the Cento1SR’s bottom bracket area that is significantly superior to that of an ordinary BB30 frame. This has been confirmed by Zedler Institute, an independent German test lab, who found the Cento1SR to have the stiffest bottom bracket area of any frame they have ever tested. BB386EVO is compatible with most traditional standards on the market. Every frameset comes with adapters to allow installation of Campagnolo, Shimano, and SRAM cranks without the need for outboard bearings, external cups or bottom bracket. FSA bottom bracket must be purchased separately.

 


 

 

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.


 

 

INTEGRATED ADJUSTER PLATE

Further evolution has been realized through the implementation of our Integrated Adjuster Plate (IAP) cable routing feature, enhancing aerodynamics as well as performance of both electronic and mechanical groups.
The IAP is integrated seamlessly into the Cento1 SR’s down tube to receive cable stops for mechanical groups or wire kits for Shimano Di2 and Campagnolo EPS electronic systems. Interchangeable based upon a rider’s chosen group, the IAP feature simplifies internal routing of cables, as well as creating a more functionally optimized as well as aesthetic solution.
In combination with a complementary and likewise integrated cable guide at the bottom bracket, IAP ensures unobstructed, noise-free and friction-free cable routing and shifting.
Furthermore, our cable stop option for mechanical groups features integrated barrel adjusters for easy access while riding, as well as additionally enhanced aerodynamics.


 

 

3D INTEGRATED CABLE ROUTING PLATE

Cable routing directed internally within the frame has been an important part of our research and development efforts. Smooth and reliable operation of the drivetrain and braking systems is an imperative part of determining optimal cable routing; in fact, it is the number one priority. This led us to develop a feature exclusive to the Cento1 SR: 3D Integrated Cable Routing Plate (3D ICRP). It is a cable guide tucked flushly in the frame beneath the bottom bracket that is designed with varied routing for each of the two cables. Unlike conventional cable guides, the Cento1 SR’s 3D ICRP is designed to promote differentiated and specific routing for optimal functionality of each of the derailleurs. The resulting profiling of the 3D ICRP integrated cable guide ensures both a sure feel at the front derailleur as well as rear derailleur performance. An essential aspect of optimal internal routing is the cable’s frictionless and contact-free movement within each of the frame tubes through which it passes. Additionally, preserving the optimal arc of rear derailleur cable and housing between the point of exit from the frame at the drive-side chainstay into the rear derailleur itself ensures smooth and “crisp” shifting across the entire cogset. As with the complementary IAP component, the frame is sculpted at the bottom bracket to receive seamlessly the 3D ICRP cable guide for Shimano Di2, Campagnolo EPS or mechanical systems. Its minimalist and integrated characteristics assimilate the guide within the frame’s profiling to further enhance aerodynamics over conventional cable guide designs.


 

 

INTEGRATED SEATMAST

We believe that a bicycle worthy of the world’s best professional riders must represent the pinnacle of performance in every aspect.
Since introducing our first integrated seatmast design as a feature of our original Cento1 model, we have never strayed from our conviction that it plays a key role in the ideal balance between structural performance, lightweight and comfort.
The Cento1 SR integrated seatmast takes the concept a step further with its Kamm truncated tail design for optimal aerodynamics.


 

 

ASSYMETRIC CHAINSTAYS

Our asymmetric chainstay design for the Cento1 AIR is the next evolution of the design concept we originally introduced in the legendary first generation Cento1. The drive side chainstay is dramatically different than the non-drive side because the forces on the two sides are dramatically different. The drive side stay's shape and lower positioning counteract chain torque, while the non-drive stay is shaped to balance those same forces from the opposite side. The lower drive-side stay also reduces typical "chain-slap" when your ride gets rough.

While our chainstays are designed with maximum stiffness and power-transfer in mind, our minimalist and vertically compliant seatstays were crafted to compliment them, dampening vibrations while simultaneously ensuring torsional and lateral stiffness for optimal power transfer.


3D DERAILLEUR HANGER


Wilier looks to every detail on our bikes to optimize performance and functionality, and our 3D Derailleur Hanger is evidence of this. Cento1SR 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.

Easily interchangeable, 3D Hangers specifically integrate to either electronic or mechanical drivetrains. For a traditional mechanical group, the hanger features a clean integrated cable stop, making the transition from internal cable routing absolutely seamless. 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 Cento1 SR’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. For electronic groups, the design is minimal, allowing 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.
