Complete Redesign of Wilier Zero.7 Results in Sub 800g Frame
In the never ending quest of lighter, better, stiffer, stronger, Wilier Triestina has a new flagship. The Zero.7 already held the top spot, but the Italian manufacturer has completely redesigned the bike to remain at the top of ultra modern race machines. That means new cable routing, improved carbon fiber techniques, better aerodynamics, all with the ride quality Wilier is known for.
Zero in on the improvements next…
One of the biggest stories with the new Zero.7 is in the carbon itself. Utilizing a new molding procedure, Wilier has managed to reduce the overall volume of the tubeset without decreasing stiffness or performance. The new method uses a special thermoplastic insert that is placed between the inside of the carbon and bladder. Thanks to the insert, Wilier has much more control over the pressure and inside surfaces of the frame as well as the thickness of the walls which results in a frame with weights under 800g (750g for size M). After the frame is formed, the bladders and thermoplastic inserts are removed.
Wilier also continues with the use of their SEI, or Special Elastic Infiltrated Film. Used in place of some lower modulus fibers in the frame’s construction, SEI Film is a special viscoelastic material that deadens road vibration and results in a stronger frame. Because of the film, Wilier can use up to 60 Ton high modulus carbon while maintaining a comfortable ride. As for numbers, Wilier says SEI Film frames are 35% more shock resistant, 18% less likely to delaminate, and 12% more flexible.
Other improvements to the frame include the introduction of an integrated fork and aerodynamic head tube. Borrowing from the Cento1 SR, Wilier shaped the front end of the Zero.7 to be more aerodynamic without affecting stack height or head tube length. Further aero enhancements have been made using development from the Twin Blade TT bike.
The Zero.7 will be rocking at BB386 EVO bottom bracket which allows for BB386 cranks along with most other standard cranksets. The wider spaced shell offers more real estate for the chainstay/DT/ST junction as well as making more room internally for the new cable system. Wilier is also introducing a new derailleur hanger system they call the 3D Hanger. Along with increased stiffness the hangers are carefully designed for both mechanical and electronic drivetrains for optimal cable/wire placement.
New cable routing is also found through the rest of the frame. Careful attention was paid to making it function for both mechanical and electronic drivetrains while delivering an aerodynamic, rattle free, and easy to service option for either. Large removable ports make accessing the internal bits easy, and any mechanical stops have smooth plugs for running electronic. When running Di2 or EPS, the wires route into the frame through the rear brake port which is locate on the top tube, just behind the head tube.
The 2015 Wilier Zero.7 will be sold in multiple colors and will arrive at retailers this fall. Expect price tags to read $4999 for framesets which include the frame, fork, seatpost, seat clamp, and headset, as well as complete bikes with Shimano Dura Ace or Campagnolo Super Record for $9499 or $10,499 respectively.
