Last year Wilier Triestina elevated their aero game with the introduction of the Twin Blade time trail bike. The radical design was a major departure for the Italian brand and signaled their intentions to compete with the major brands at the WorldTour level. A year later Wilier Triestina has taken what they learned in the development of the Twin Blade and applied it to their first aero road bike, the Cento1 Air.
The Cento1 Air enters near the top of Wilier Triestinas line and offers a more aerodynamic option when held up next to the more conventional shaped Cento1 SR. Like the Cento1 SR it is constructed from 60T Carbon with Wiliers ZnO nano-treatment for increased stiffness and lower weight. Key aerodynamic elements from the Twin Blade are evident in the channeled fork design, and the Kamm-tail tubing shapes found throughout the frame. Another aero element taken from the Twin Blade is the low placement of the seat stays, which connect to the seat tube well below the seat and top tube junction. This placement is not only more aerodynamic, but also effectively hides the rear brake from the wind.
To further enhance aerodynamics, the Cento1 Air integrates the fork into the frame. It is integrated externally where the crown and head tube intersect, but also underneath, allowing the fork to channel air smoothly onto the down tube. Wilier Triestina rounds out the aerodynamic package with internal mechanical and electrical cable routing and an aero seat post.
Knowing that cheating the wind is of little use without direct power transfer, Wilier Triestina outfitted the Cento1 Air with an oversized BB386EVO bottom bracket, developed along with BH and FSA. The use of the BB386EVO system creates a large bottom bracket shell, which Wilier Triestina uses to merge the down tube, seat tube and chain stays into a stiff and efficient structure.
Available in the fall, retail price for the frame, fork, headset, bottom bracket and seat post is $4000. There will also be two complete bikes available. One with an Ultegra Di2 build kit, and the other with a combination of Dura Ace and Ultegra 11-speed mechanical. Both will retail for $5000.
