Italy’s Wilier Triestina Launches Aero Road Bike

Aero News Road Bike

Meet the brand new Wilier Triestina Cento1 Air.

Add Wilier Triestina to the long list of bike makers offering some variation of an aero road bike. The Italian bike maker revealed its new wind cheater – dubbed the Cento1 Air – at a small media gathering in Boulder, Colorado on Thursday.

In the U.S. the new steed will be available with Ultegra Di2 spec or a blended Dura Ace-Ultegra 11-speed mechanical set-up with Fulcrum Racing Zero wheels for $5,000. Or you can opt for frame, fork, headset, bottom bracket and seat post for $4,000. There are six standard sizes from XS to XXL and three color options. Availability is set for fall 2013.

As those price points indicate, the Cento1 Air will be positioned at the upper end of the Wilier road line, along with the Cento1 SR and Zero.7, both carry-overs from the 2013 product line.

But the new bike traces much of its lineage to Wilier’s top-tier time trial machine, the Twin Blade. This design kinship is evidenced in the Cento1 Air’s channeled fork design and aero-enhancing Kamm-tail frame tube shapes.

The integrated fork utilizes a pair of channels that reside just above the top of the tire, which Wilier claims help control airflow while at the same time maintaining overall frame stiffness. That rigidity is further enhanced by a design that effectively increased the length of the head tube, creating a stronger squared shape.

Further back, the Cento1 Air uses a BB386EVO bottom bracket, which was developed by Wilier in conjunction with FSA, and is purported to improve power transfer. The BB386EVO is also compatible with a wide variety of cranksets (down to 24mm) including Shimano and Campagnolo, but not BB30. Additionally it allows for the use of oversized asymmetrical chainstays, which are designed to better manage drivetrain and riding forces.

“You can’t just make a really skinny bike and call it aero,” explained U.S. PR man Jasen Thorpe about a bike that boasts an integrated aero front fork, aero rear stays, and an aero seat post. “Wilier designed this bike as a complete system that kept the rider in mind.”

Other notable highlights include that monocoque aero seat post that’s made for Wilier by Ritchey, and includes an internal lock nut that prevents slippage. The larger seat tube maintains the aero theme, fully covering the rear brake caliper. The cable guide cover is integrated into the frame, maintaining the clean aero profile. All cables run inside the downtube. And Wilier has scrapped the traditional cable tension adjuster in favor of an adjuster plate that’s integrated into the frame. If you opt for an electronic groupset, Wilier includes a second plate to interface with that system.

The Zero.7 remains Wilier Triestina’s flagship bike for 2014.

The rest of the 2014 Wilier Triestina line is carry-over from last year, and includes the Zero.7 ($5,000 for frame, fork, seat collar, headset and bottom bracket); Zero.9 ($3,900 for frame, fork, bottom bracket, headset, seat collar, or $5,000 with complete SRAM Force build); and the Cento1 SR ($4,000 for frame, fork, headset, bottom bracket, seat mast topper).

Wilier Triestina Zero.7

The Zero.7 utilizes BB386EVO and SEI film to enhance stiffness and strength-to-weight ratio, while maintaining vibration damping and impact resistance. The complete frame is claimed to weigh under 800 grams.

Wilier Triestina Cento1 SR

The Cento1 SR sits between the Zero.7 and the new Cento1 Air, boasting the BB386EVO bottom bracket and Kamm tail aerodynamics on the fork and seatpost, and striking a balance between the low-weight design of the Zero.7 and the aero-first design of the Cento1 Air.
