The S-Works Tarmac SL9 is the fastest road bike ever made—delivering the lowest real-world Time to Finish of any road bike. It’s not defined by a single breakthrough, but by how aerodynamics, weight, stiffness, and ride quality work together as one complete system.
When riders line up to race, the objective is simple: cross the line first. Tarmac SL9 converts more effort into speed across real race conditions—validated on World Tour courses, terrain, and scenarios that actually decide outcomes.
Time to Finish. The only metric that matters
Engineered around real race outcomes, not isolated numbers. Tarmac SL9 delivers the lowest total race time of any road bike we’ve tested.
Our most aerodynamic road bike
4 watts faster at race speeds, with every tube shaped to manage airflow with a rider in motion.
Nothing is lighter
A 687g FACT 12r frame and complete builds starting at 6.5kg set the benchmark for aero road weight.
A system of speed
Aerodynamics, weight, stiffness, and compliance are developed together—not in isolation—to deliver speed that shows up across the entire race.
Unmatched ride quality
Rider First Engineered performance with telepathic handling and balanced compliance delivers speed riders can sustain all day.
