S-Works Tarmac SL9 - Shimano Dura-Ace Di2
Time to Finish
Tarmac SL9 was proven through the most comprehensive road race simulations ever created. The result? Tarmac SL9 would have made Demi Vollering 14 seconds faster in the final stage of the 2024 Tour de France Femmes. The difference between heartbreak and history.
Aero Where it Matters
The Tarmac SL9 is the most aerodynamic road race bike we’ve ever tested. Drawing directly from Tarmac SL8 learnings and decades of aero research, every tube on Tarmac SL9 was re-sculpted for speed at World Tour races.
Speed Sniffer
The Speed Sniffer head tube is now 4 mm narrower, delivering a 10 percent reduction in frontal area.
Win Fin
The Win Fin channels airflow around the rear for the true aerodynamics of breakaway racing.
Dropped Downtube
We added a dropped down tube that works in tandem with the Speed Sniffer and Flow Fork.
Flow Fork
A breakthrough twisted‑blade design delivers smoother airflow and measurable drag reduction.
S-Works Rapide Post
A deeper, cleaner aero post profile reduces drag in the zone most affected by pedaling airflow.
Fastest Road Bike Ever Made
The Tarmac SL9 delivers the lowest real‑world Time To Finish of any road bike we have ever tested. When the goal is to cross the line first, no road bike gets you there faster.
One with the Bike
Speed everywhere, all day. Telepathic handling, instant response, and sublime compliance unite to make you one with the bike.
Rider First Engineered
Every size from 44cm to 61cm receives the same uncompromising performance.
Nothing is Lighter
Flow State Design Delivers 687 Gram Frame
14 Seconds Faster
Demi Vollering would have won the Tour de France Femmes by 10 seconds on Tarmac SL9.
Moving Leg Mannequin
Win Tunnel testing incorporates our 6th Gen Moving Leg Mannequin.
Made in Racing
Aerodynamics and rider data alone are not enough to create the fastest bike for the fastest riders.
