The Wilier Zero SLR is the first ultra-lightweight racing bike with disc brakes and fully integrated cables.
Wilier Zero SLR encapsulates the most complex concepts of lightness and total integration in simple aesthetics. These are the features the most demanding cyclists seek in the most technologically advanced racing bikes: ultra-lightweight, high-speed stability and control, braking performance, electronic transmission, high aerodynamics, and full cable integration. All condensed in Wilier’s unmistakable style.
ULTRA-LIGHTWEIGHT RACING FRAME A distinctive feature of the Wilier Zero SLR is its lightweight frame: weighing in at under 800 grams in the medium matte black version, Wilier 0 SLR is the most distinguished member of Wilier Triestina’s range of super lightweight frames. In fact, in its most advanced configuration, the entire bike tips the scales at a mere 6.5 kg.
TOTAL INTEGRATION One of the trends most highly appreciated by the public at large is the search for extreme clean lines. Already in 2016, Wilier Triestina started down this road (one of the first bike manufacturers worldwide to do so) with Cento10AIR, inserting the brake and derailleur cables inside the monocoque handlebar which was integrated with the frame. With the Wilier 0 SLR, we raised the bar, pairing total integration with the lightest frame, fork, and handlebar lever. We've re-engineered and evolved all these elements allowing integration: the 0 integrated handlebar, composite handlebar spacers and the section of the frame headset.
STIFFNESS TO WEIGHT High STW values are synonymous with performance in carbon frames. Most of the time, we add material to increase a frame’s stiffness, thus increasing its weight. But, when weight is to be reduced, stiffness is at risk, and consequently, handling and handling safety as well. On the Wilier Zero SLR, thanks to the blend of carbons, the unique positioning of the fibers and the construction technology, we have succeeded in attaining the highest level of lightness and stiffness, exceeding the STW value of our previous Zero.7 and Zero.6 models by 24%.
EASY-FIT SPACERS 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.
SPEED RELEASE THRU-AXLE SYSTEM Another new feature is the Mavic Speed Release thru-axle system that enables the wheel to be quickly removed from the frame. In this way, the axle does not need to be totally extracted from the wheel hub. This solution significantly reduces wheel release and insertion time. During races, this solution cuts wheel change times by 7 seconds on average compared to a traditional thru-axle system. We also chose the Speed Release thru-axle to reduce weight (only 85 grams per pair) and safeguard the integrity of the frame
ASYMMETRY BECOMES THE SOLUTION The transmission of power to the rear wheel must not be subjected to dispersions that cause a loss of pedaling 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.
SEATPOST AND CLAMP Wilier Zero SLR 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.
BALANCED DESIGN 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.
