First developed in 2014 as a top of the line aero road race bike, the Cento1AIR is now positioned as a great value in the mid-range price point. In past seasons, Cento1AIR has been raced professionally by Wilier - Selle Italia, United Healthcare, and SmartStop among others, so it is a high performing all-around racing bike with proven results. The frameset comes with seatpost, headset, and fork, and is available in stock in White/Black/Blue only. For other colors, please contact us to place a special order.
The fork is the first part of the frame to hit wind resistance. This is where we began in our evolution 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 as a road 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.
The Cento1AIR uses a PressFit86 bottom bracket, which gives the frame a wide and stiff platform to build upon, while being an easy to find BB standard. The wide BB shell also let us design massive rear seat stays. In keeping with the long-held Wilier Triestina tradition, they are also asymmetric. The asymmetric rear stays improve pedaling efficiency against the torque generated by the chain.
Cento1AIR's seatpost is designed by Wilier Triestina design and produced by Ritchey in carbon monocoque. We've designed it to integrate seamlessly with the sophisticated aerodynamics of the frame. The locking mechanism is combined. Simple yet intelligent at the same time, the aero remains incredibly secure. There are two fastening systems which work together simultaneously. The internal wedge fixes the post inside the seat tube. The external clamp keeps the post in place by preventing it from slipping. In developing the Twin Blade, we learned that if the rear oblique seat stays are kept as low as possible, the aerodynamics of the frame are improved. 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. A clean cut, creating a virtual 'fin' from an aerodynamic point of view, but which still allows them to remain light. Compared to other solutions, the rear brake installs to the frame in a standard way, with a normal socket wrench, without requiring additional parts.
