Every Tarmac is developed with the same obsession: winning races
Every Tarmac is developed with the same obsession: winning races. Not in theory or in perfect conditions, but in the moments that actually decide outcomes. The moments when riders commit, and when they need to trust that their equipment will help them to cross the finish line first.Modern road racing has become more demanding. Races are longer, speeds are higher, and margins are smaller. Riders constantly move between the bunch, breakaways, climbs, and finales, adapting to changing terrain, wind, and race dynamics. Performance is no longer defined by a single dominant attribute, but by how efficiently speed can be sustained across the full duration of a race. Tarmac SL9 was developed inside this reality. Built from racing, tested with riders, and shaped by the conditions that decide World Tour outcomes. Rather than optimizing for isolated numbers, SL9 was engineered around a single question: how do we reduce total race time where it matters most? Answering that question required redefining speed itself.
Time to Finish: The Only Metric that Matters
When the objective is winning races, the goal is brutally simple. Get riders to the finish line faster. For Tarmac SL9, that meant answering one question with absolute confidence: Does this bike reduce total race time on the fastest, hardest, steepest, longest World Tour courses on Earth?
To answer that, we built the most comprehensive road race simulation system ever created.
The Result? The Tarmac SL9 would have made Demi Vollering 14 seconds faster during that decisive last stage in the Tour de France Femmes in 2024. A 14-second gain on a Tour decided by 4 seconds. The difference between losing the overall… or winning it by 10 seconds.
Aero Where it Matters: 4 Watts Faster
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. Nothing is Lighter: Flow State Design Delivers a 789 Gram Frame
Tarmac SL9 rewrites the aerodynamics of the entire front half of the bike with a thinner Speed Sniffer, a dropped downtube, and the new Flow Fork, which work together to manage high‑pressure airflow more efficiently. At the rear, the Win Fin reshapes the seat tube and triangle around real race conditions, delivering meaningful aerodynamic gains when it matters most. A re‑engineered Aero Post further reduces drag in the zone most affected by pedaling airflow, completing a system designed for maximum speed in real‑world racing.
Nothing is Lighter: Flow State Design Delivers 687 Gram Frame
At 687 grams, the S-Works Tarmac SL9 frame stands alone at the top of the road aero category. Complete builds start at 6.5 kg—a number most climbing-specific road bikes and the UCI can only dream of. Oh, and yes, that includes Roval Rapide CLX III wheels and Roval Rapide Cockpit. This was made possible by Flow State Design, first pioneered on the Aethos road bike.
Specialized Tarmac SL9
The all-new S-Works Tarmac SL9 is the fastest road bike ever made. Not just because it’s the lightest. Not just because it’s our most aero. Not because it handles better than anything else on the road. But because it delivers the lowest real-world Time to Finish of any road bike ever made. Tarmac SL9 turns more of your effort into pure speed—validated for real racecourses, real terrain, real riders. When the goal is to cross the line first, no road bike gets you there faster.
