A new milestone has been reached at Casa Wilier. The Cento1’s fifth generation is now a here. After Cento1, Cento1SL, Cento1SLR and Cento1SR, we wanted to push ourselves further. Once again.
The basis for this 2014 development has been to bring us closer to the aerodynamic efficiency of the TwinBlade, coupled with the Cento1’s versatility and performance. Cento1 is now working with the the wind. Performance, efficiency, comfort and now even more aerodynamic. Cento1AIR represents the culmination of all of our knowledge acquired in recent years.

Wilier Cento1Air


Zero.7 is the lightest bicycle Wilier Triestina has ever made, and the revolution it leads has a specific goal: setting the new design standard for ultra-light racing bikes . The frame weighs under 800 grams, but the technology applied to it differs from those normally used in this type of bicycle. The team of engineers in Rossano Veneto applied technologies to the Zero.7 that were developed for the Cento1SR and Cento1 AIR: cable integration, integrated fork, and better aerodynamic efficiency to name only a few. Zero.7 is therefore the natural evolution of the Zero.7 platform as we have known and ridden it thus f ar. The most noticeable apsect of the new frame is the shape, featuring less volume than the previous version of the Zero.7. New construction techniques have allowed us to reduce the volume of the frame tubes by 19%. However, the smaller diameter tubes have not reduced lateral stiffness or the safety of the frame. Quite the contrary. In the process of producing the Zero.7 monocoque frame, we use an internal liner made of a special thermoplastic material, into which the bladder is inserted. This internal liner helps to create a uniform and equal pressure along the inner carbon walls of the frame. With this process, we achieve total control over the thickness and smoothness of the frame walls. Thus the pressure exerted on the inside of the frame from the bladder is distributed equally over all points on the frame. This construction technique allows us to give the frame considerable stiffness at the most critical points without adding carbon to these parts, keeping the frame ultra-light.


The fork is the first part of the frame to hit wind resistance. This is where we began in our revolution of the Cento1. We posed a relatively simple question, which required an incredibly sophisticated answer. How do we replicate the aerodynamic efficiency of the TwinBlade’s fork, but in a conventional fork? Using the rigidity already developed in the Cento1SR’s integrated fork shape (a 14% increase in torsional rigidity in comparison with Cento1, thanks to the repositioning of the down and horizontal tubes in relation to the headtube), we have now created 2 small channels below the fork’s crown, in line with the TwinFork concept in the TwinBlade. These two small channels aid airflow, while enabling increased rigidity. The down tube, in its new lowered position, integrates seamlessly with the fork crown while generating another air foil which is capable of reducing wind resistance even more. The fork’s brake entry hole is hidden by the down tube, which keeps it clean and well protected.

We have also very carefully examined how to route cables and cable housing inside the frame. We were aiming for the smoothest cable operation when we designed and analyzed this system. It consists of a new type of cable routing plate that has been incorporated below the bottom bracket. A standard plate normally directs the two cables – front and rear derailleurs – with equal angling.


Our cable system has been further enhanced by routing the cables inside the frames’s tubes. Our INTEGRATED ADJUSTER PLATE (IAP) is a special device which allows for the fastening and adjusting of cables. IAP seamlessly integrates with the frame, thereby bestowing Cento1SR with a very clean look where no elements are exposed to air resistance


The dropout evolves and implements its name. The 3D DROPOUT is born. It is not a mere rear derailleur mounting plate anymore. The dropout now extends over a third dimension and serves also as a cable stop. This newly acquired third dimension leads to an especially stiff dropout compared to conventional fastening plates. Thanks to its generous size, we were able to create two holes (a larger one for the mechanic group set cable and a smaller one for the electronic cable) to route cable housing or cables without compromising the dropout’s stiffness


In developing the TwinBlade we have learned that if the rear oblique seat stays are kept as low as possible, the aerodynamics of the frame are improved. This is what we have done also with the Cento1AIR, moving the stays as low as possible, within UCI standards. The rear brake is entirely covered by the stays. As with many other frame parts, the vertical stays have also been designed according to the Kamm theory
