Slovakian Peter Sagan stormed to the win at the 2015 UCI road world championships in bold solo fashion, attacking on the final hill and holding his advantage to the line. He did so aboard a custom-painted Specialized S-Works Tarmac.
While some elements of the build are fairly straightforward, such as the alloy FSA Energy Traditional Bend bars or Look KeO Blade pedals, some parts are clearly unique to Sagan's physiology, like the 140mm Zipp SL Sprint stem that lunges forward like the figurehead on a ship's prow.
While team sponsor Specialized introduced the new Venge ViAS aero bike earlier this year, Sagan opted to stick with his tried-and-true Tarmac.
