In this world, there are bikes, there are bikes that win races, and then there are bikes that start revolutions on the road. The S-Works Tarmac eTap falls into the latter group. It features an impeccable S-Works FACT 11r carbon fiber construction that's unbelievably light, stiff, and reactive. In other words, it's purpose-built to be a true all-'round race bike, which is no accident. In fact, it comes as a result of our Rider-First Engineered™ design that applies specificity to every tube size and carbon layup for every frame size. This creates the optimal balance of rigidity, weight, and responsiveness, so every frame, regardless of size, performs just as we intended. And if you need proof, just look at the Tarmac's trophy case, with wins in every Grand Tour and the last two World Championships. Of course, a frame of this pedigree only deserves the utmost in dressings, which is why we outfitted it with SRAM's latest greatest wireless shift system, eTap, and a bevy of Body Geometry components that maximize performance by providing the utmost in comfort. So if you're in need of a future-proof bike, you just found your match.
