Wilier Cento 1 Air Ultegra Di2 Road Bike. Each year, Wilier strives to advance the Cento1 Air and this Cento1 Ultegra Di2 Air Road Bike is no different. Striving for maximum aerodynamic efficiency, this full carbon road bike comes with an aero fork, seatpost, and rear stays. You will also enjoy clean lines with integrated cables, a 3D Dropout, asymmetric rear arms, and an Integrated Plate Adjuster. All-in-all, this svelte aero machine is made to slice through the wind Light, Aerodynamic Performance. The complete Shimano Ultegra Di2 drivetrain offers smooth and swift electronic shifting with a stiff and efficient 50/34T crankset. Coming with a Shimano WH-RS500 wheelset, this lightweight carbon machine is race-ready. Designed for total aerodynamic performance, the Carbon 60TON frame and fork combination delivers the perfect balance of stiffness, comfort, and weight-savings. Stacked with technological gains to make this carbon road bike a fast and efficient racing machine, the podium beckons for those who ride the Cento1 Air Road Bike Features: Frame: Carbon Monocoque Fibre 60TON Fork: Carbon Monocoque Fibre 60TON Chainset: Shimano Ultegra R8000, 11-speed, 50/34T BB Shell: Shimano Ultegra PressFit Brake/Shift Levers: Shimano Ultegra 8050 Front Derailleur: Shimano Ultegra 8050, 11-speed Rear Derailleur: Shimano Ultegra 8050, 11-speed Cassette: Shimano Ultegra 8050, 11-speed, 11-28T Chain: Shimano Ultegra 8050, 11-speed Wheelset: Shimano WH-RS500 Tyres: Vittoria Zaffiro Pro Brakes: Shimano Ultegra 8000 Handlebar: FSA EnergyStem: FSA Energy Headset: Ritchey Pro Saddle: Selle San Marco – Squadra Seatpost: Ritchey Carbon custom Cento1 Air Technologies: Carbon 60TON: To build a great monocoque carbon frame, Wilier looked for the perfect balance of stiffness, comfort and responsiveness at the lightest possible weight. Carbon fibre is an ideal material for bicycle frames because of its qualities of elasticity, capacity to withstand stresses, and its strength-to-weight ratio. The higher the modulus, the stiffer the composite. On the other end of the spectrum, the lower the modulus, the more elastic it will be. In the construction of this bike they implemented MR60H for stiffness in the critical stress areas where lateral stiffness equates to greater efficiency. Then used T800H and T700SC, with more elastic characteristics, to ensure comfort and sure-footed handling. Each was used as minimally as possible once our demanding strength and durability standards were met, ensuring the lightest weight frame possible. Asymmetric Rear Arms: Thanks to the solid central BB386 EVO movement, Wilier designed generous rear seatstays and, in keeping with the long-held Wilier Triestina tradition, they are asymmetric. Concept symbol of the Cento1, the asymmetric rear stays improve pedalling efficiency against the torque generated by the chain Integrated Cables: The brake and derailleur cables flow inside the frame. This allows the frame to be aerodynamic, protect and cover the cables. Integrated Aero Fork: The fork is the first part of the frame to hit wind resistance. This is where Wilier began in their revolution of the Cento1; they posed a relatively simple question, which required an incredibly sophisticated answer. How do you 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), Wilier 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 downtube, 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 downtube, which keeps it clean and well protected. Aero Seatpost: A Wilier design and Ritchey production in carbon monocoque. Wilier 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 first, internal part, locks the saddle to the frame. The second, a clamp, locks the saddle in place by preventing it from slipping into the saddle tube. Aero Rear Stays: In developing the TwinBlade Wilier learned that if the rear oblique seatstays are kept as low as possible, the aerodynamics of the frame are improved. This is what they 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. A clean cut, creating a virtual “fin” from an aerodynamic point of view, but which still allows them to remain light and within UCI rules. Compared to other solutions, the rear brake installs to the frame in a standard way, with a normal socket wrench, without requiring additional parts. Integrated Plate Adjuster: The cable system has been further enhanced by routing the cables inside the frame’s tubes. The Integrated Plate Adjuster is a special device which allows for the fastening and adjusting of cables. Integrated Plate Adjuster seamlessly integrates with the frame, thereby bestowing a very clean look where no elements are exposed to air resistance. Easily interchangeable to be compatible with different electronic group sets, the Integrated Plate Adjuster allows one to route cables inside the tubes and to redirect them towards the bottom bracket. Combined with the special cable guide plate located under the bottom bracket, Integrated Plate Adjuster keeps cables neatly spaced from the downtube’s inside surface. Noise and shifting efficiency loss can occur when a cable does not maintain its position. 3D Dropout: 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, Wilier created 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 stiffness of the dropout. In this manner, the dropout may be used both for mechanical and electronic group sets. For the mechanical group set, it allows one to use a shorter cable housing sleeve and to have the shifter cable follow its natural curve since the rear derailleur cable is located closer to the fastening point. This improves shifting efficiency and smoothness. The exit routing is not the only improvement. The cable stop has been positioned above the drive-side chainstay, thereby keeping the cable flawlessly suspended within the stay. The internal cable routing through the down tube is kept at a distance from the frame’s inner surface to assure that there is no friction during shifting. The wiring exit point of the electronic group set has also been optimised as it is setback and above the drive-side dropout. This feature facilitates and expedites rear wheel removal and installation Easy Assembly. When you order a bike, one of our trained mechanics will carefully prepare and pack your bike for shipping. Upon delivery, the assembly is simple and all necessary tools are conveniently included in the box Depending on the delivery service and destination, bikes will either be delivered in a large or a small box. Below is a guide as to how your bike will arrive:All bikes for delivery within the UK and Republic of Ireland will be delivered in a large box, except for kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes. All bikes for delivery within the EU on a standard service will be delivered in a large box. If an express delivery option is chosen, your bike will be packed into a small box. Again, the exception is kids’ bikes and BMX bikes, which are always delivered in manufacturer’s boxes. All bikes for worldwide delivery outside the EU will be delivered in small boxes This video demonstrates assembly from a SMALL BOX This video demonstrates assembly from a LARGE BOX Buy Wilier Bikes from Chain Reaction Cycles, the World’s Largest Online Bike Store.
