Specialized's pinnacle carbon race machine converts every watt into the fastest real-world finish time
The S-Works Tarmac SL9 Frameset is the platform where Specialized's aerodynamic and climbing priorities finally stop working against each other. Rider First Engineered geometry scales the FACT 12r carbon frame from 44cm to 61cm so the ride character holds across the full size run, not just the middle of the range.
What Our Gearhead® Experts Are Saying:
"I've ridden a lot of race bikes that feel fast on flat roads and then fall apart on a punchy climb or a technical descent. The SL9 holds its edge across all of it."
Building up the S-Works Tarmac SL9 Frameset and want help dialing in the right spec? Our Gearhead® Experts know this frame inside out. Reach out, and we'll help you put together a build that matches how you ride.

S-Works Tarmac SL9 Frame
The Fastest Way To The Line
Proven in real race simulations, not just wind tunnel numbers
Inside The Tarmac SL9
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.
Flow Fork
A breakthrough twisted‑blade design delivers smoother airflow and measurable drag reduction.
Dropped Downtube
A dropped down tube works with the Speed Sniffer and Flow Fork, closing the gap ahead of the frame for clean airflow.
S-Works Rapide Post
A deeper, cleaner Aero Post profile reduces drag in the zone most affected by pedaling airflow.
Aero Where It Matters
4 Watts Faster
Tarmac SL9 is the most aerodynamic road race bike Specialized has tested. Every tube is re-sculpted for speed, based on Tarmac SL8 data and decades of aero research.
One With The Bike
Carbon layup is tuned zone by zone to control stiffness and compliance across the frame. Combined with race-specific geometry, that tuning makes the bike respond the way a rider expects, corner after corner.
Rider First Engineered
Every size from 44cm to 61cm gets its own carbon layup, tuned to that size's performance targets. That keeps stiffness, compliance, and handling consistent across the whole size range.
