Wilier Triestina 0 SL Disc Ultegra Di2 RS171

Wilier 0 SL takes advantage of the SLR version, the bike used by the professional riders of Astana Premier Tech and Total Direct Energie. The design is identical to the Wilier 0 SLR but with its own graphics. Moreover, Wilier 0 SL copies the steering qualities (and therefore geometries) of the SLR version.

All cables (electronic and mechanical) run inside the frame. With the new Stemma SL stem, the bike can be assembled or maintained without having to remove the handlebar.

The spacers between the frame headset and the handlebar are made of a high-stiffness composite material, with a special cavity for the cables. They are composed of two parts for quick assembly and disassembly without interfering with the cables running from the handlebar to the frame.

The transmission of power to the rear wheel must not be subjected to dispersions that cause a loss of pedalling efficiency. To meet this demand, we created an asymmetrical rear triangle with the seat stay at a slightly sharper angle than the right. This prevents lateral oscillation due to the force exerted by the cyclist on the chain, thereby turning asymmetry into a solution.

Six sizes, one feeling. The sections of the tubes of various sizes were designed to maintain consistent rigidity, handling quality and comfort on every frame size. Specifically, during the design phase we created a different section for the main tubes for each size of bicycle in order to increase the frame's torsional stiffness and stability.

Wilier 0 SL comes with a new type of carbon monocoque seatpost specially designed for this bike. Its slender shape resembles the truncated dovetail profiles of our aerodynamic Cento10PRO and Cento10NDR models. It's available in two geometries, one with a 0 mm setback and the other with a 15 mm setback, both of which are compatible with the Ritchey 1-Bolt seatpost clamp. The seatpost is attached to the frame with an expander positioned inside the horizontal tube for ultimate aesthetics and aerodynamics.
