Specialized S-Works Tarmac SL7 Dura-Ace Di2 Road Bike 2023
Why should you have to make a choice between aerodynamics and weight, or between ride quality and speed? The answer is simple, you shouldn't. The latest Tarmac model solves this dilemma – climb on the lightest bike permitted by the UCI regulations and then descend on the fastest one. Utilizing cutting-edge technology, from the FreeFoil Shape Library to the Rider-First Engineered™ frame, the Tarmac delivers a race bike that has no compromise. The days of having to make sacrifices between "aero" and "lightweight" bikes are long gone, thanks to the Tarmac - the quickest race bike ever created. It's the one bike to rule them all.
To complement the world's fastest frame, only the finest components will do, which is why Shimano's Dura-Ace group with a power meter and Roval's new CLX Rapide wheels with exceptional stability and aerodynamic capabilities are included. The S-Works Tarmac is a top-of-the-line racing machine, right out of the box.
