S-Works Tarmac SL9 Frameset

• 687g FACT 12r Carbon Frame: The lightest frame in the aero road category, built without compromise. Flow State Design optimizes tube shape to carry load rather than adding material, resulting in a lighter, stiffer, and more compliant structure simultaneously.
• Win Tunnel Engineered: Every tube profile on the SL9 was reshaped in Specialized's own Win Tunnel, tested with a full rider in motion rather than bike-only protocols. The result is 4 watts less drag than the SL8 at race speeds.
• Speed Sniffer Head Tube: Now 4mm thinner with a 10% reduction in frontal area, achieved through a patent-pending Offset Steerer design that reroutes the rear brake cable to make room without sacrificing internal routing.
• Flow Fork and Win Fin: Twisted fork blades guide airflow more efficiently along the frame, while the Win Fin at the rear is tuned for real breakaway configurations: one bottle, not two, saving an additional 0.5 watts.
• Rider First Engineered: Every size from 44 to 61cm receives a size-specific carbon layup, delivering consistent stiffness, compliance, and handling across the full range.
• S-Works Aero Carbon Post Included: The same seatpost raced by World Tour pros, featuring the thinnest section Specialized has ever made at the most aerodynamically sensitive point of the frame.

Riders who want to build the world's fastest road racing platform to their exact specification, with no component compromises.
