Wilier 0 SL takes advantage of the SLR version, the bike used by the professional riders of Astana Qazaqstan Team. 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.

The transmission of power to the rear wheel must not be subjected to dispersions that cause a loss of pedalling efficiency. Wilier 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.
