Specialized S-Works Tarmac SL8 Frameset

The S-Works Tarmac SL8 is the result of over two decades of continuous development, bringing together aerodynamic gains, weight savings, and supreme ride quality. Designed in collaboration with Specialized’s Ride Science team, every element of the SL8 has been tested and proven through rigorous race simulations. The result? A frameset that shaves off 16.6 seconds over 40km, making it the fastest Tarmac ever.

Specialized has pushed aero performance to new heights with the Tarmac SL8. The innovative Speed Sniffer nose cone directs airflow efficiently, reducing drag and enhancing speed. The narrow, aero seat post further contributes to smoother air flow, ensuring you cut through the wind with ease.
At just 685g, the S-Works Tarmac SL8 is the lightest Tarmac yet. Lessons learned from the ultra-light Aethos have been implemented to ensure critical areas of the frame remain as lightweight as possible while maintaining strength and stiffness. This makes climbing easier and acceleration sharper, giving you an edge when it matters most.
With a 33% improvement in stiffness-to-weight over the SL7, the SL8 delivers lightning-fast responsiveness without compromising comfort. Whether you're tackling steep mountain passes or sprinting for the finish line, the Tarmac SL8 provides a smooth yet direct ride that responds to every pedal stroke.
Breaking away from traditional gender-based designs, the Tarmac SL8 is built for all cyclists. Its Rider-First Engineered approach ensures that every frame size delivers the same level of performance, stability, and handling, regardless of rider build or weight.
The SL8 frameset features a 68mm threaded bottom bracket for ease of maintenance and reliability. Flat-mount disc brake compatibility ensures powerful stopping performance in all conditions. With tyre clearance up to 32mm, riders can enjoy added versatility without sacrificing speed.
Occasionally, without notice, manufacturers change product design and/or specifications.
