S-Works Tarmac SL9 Shimano DURA-ACE Di2
The S-Works Tarmac SL9 is built around one question: how do you get to the finish line faster than any other road bike on the planet? The answer is a 687-gram FACT 12r carbon frame, re-engineered from every tube profile to deliver 4 watts less drag than the SL8, with complete builds starting at 6.5kg. This Dura-Ace Di2 build pairs that platform with Shimano's flagship 12-speed electronic drivetrain, a 4iiii Precision Pro dual-sided power meter built directly into the crankset, and a Roval Rapide CLX III wheelset developed in the Win Tunnel alongside the frame to perform as one system. When the goal is to cross the line first, no road bike gets you there faster.

Why we like the Specialized S-Works Tarmac SL9 Shimano DURA-ACE Di2
System-Level Aerodynamics
The Roval Rapide CLX III wheels were developed in the Win Tunnel alongside the SL9 frame as one system. The asymmetric depths aren't arbitrary; they're the result of testing with a full rider on board, which is the only way aero numbers actually mean anything.
Shifting That Matches the Frame
Dura-Ace Di2 is the natural partner for a bike engineered to win World Tour races. Electronic actuation is immediate and consistent at 100 rpm or under maximum fatigue, so the only thing you're thinking about in the decisive moment is the move itself.
Built-In Power Data
The 4iiii Precision Pro dual-sided power meter lives inside the Dura-Ace crankset, so there's nothing to add, mount, or worry about losing mid-race. Left/right power balance comes standard on a bike at this level, which is exactly how it should be.
