Wilier Cento 1 SR SRAM Red
Evolution is nothing without an origin. When we developed the Zero.7, we sought to perfect power transfer, maximizing every watt of a rider’s effort. In designing our time trial bikes, we learned how to control the flow of air. Our experience with the Cento1 confirmed that the integrated seatmast is vital for those who demand the best performance from their bike. We combined these elements from our origins, and then the insight and experience of Wilier Triestina did the rest. Cento1SR. The evolution begins today.
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.
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.
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.
Another of the evolved SR features rooted in the original Cento1 design is our drive-side chainstay. Its shape and lower positioning counteract chain torque, while the non-drive-side chainstay is conversely designed to complement and work in conjunction with the drive-side stay.
The lowered drive-side stay also does away with “chain slap” typical of conventional designs, especially when traversing rough road surfaces. At the same time, our minimalist and vertically compliant seatstays have been designed to complement the oversized chainstays by dampening vibrations while ensuring torsional and lateral stiffness for optimal power transfer.
3D DERAILLEUR HANGER
Our optional derailleur hangers no longer merely represent simple component parts to facilitate standardized installation of a rear derailleur. Cento1 SR derailleur hangers have assumed a third dimension of functionality, facilitating different systems as well as serving as cable stops. In addition to these rich new features, our 3D Derailleur Hangers are also much stiffer than conventional rear derailleur hangers.
Easily interchangeable, 3D Derailleur Hangers specifically facilitate either electronic or mechanical drivetrains. For mechanical groupsets, the hanger features a standard cable stop. For electronic groupsets, the specifically designed hanger features a simple opening through which passes the electronic wiring.
