The Specialized Tarmac SL8 Road Bike is the fastest race bike in the world, combining unmatched aerodynamics, lightweight design, and exceptional ride quality. After eight generations and over two decades of innovation, the Tarmac SL8 is not just the fastest Tarmac ever, it’s the ultimate race bike.
Speed is more than just aerodynamics or lightweight construction; it’s the perfect balance of both, along with stiffness and compliance. The Tarmac SL8 achieves this with a race-proven design that’s 16.6 seconds faster over 40km, 128 seconds quicker at Milan-San Remo, and 20 seconds ahead on the legendary Tourmalet climb.
Aero where it counts. The Tarmac SL8 is Specialized's most aerodynamic road bike yet, surpassing even the Venge. With a new "Speed Sniffer" nose cone design, the Tarmac’s leading edge is optimised for minimal drag. The head tube is narrower, and the seat post is the most aero Specialized have ever made, ensuring smoother airflow around the legs for maximum speed.
Minimum weight, maximum aero. Drawing from the Aethos, the Tarmac SL8 is built to the UCI weight minimum, featuring a 685g frame that’s 15% lighter than the Tarmac SL7. This lightweight frame, combined with a full aero setup, delivers exceptional speed and performance. The design efficiently distributes load, making extra carbon layers unnecessary.
Unmatched ride quality. The Tarmac SL8 offers a 33% improvement in stiffness-to-weight over the SL7, enhancing handling, responsiveness, and comfort. Thanks to Rider-First Engineering, every size delivers consistent, superior ride quality. With 6% more compliance, the Tarmac SL8 glides smoothly over rough roads, maintaining the proven geometry and 32mm tyre clearance of the SL7 for easy adaptation.
Beyond gender. The Tarmac SL8 is designed for every rider, regardless of gender. Instead of creating male or female-specific bikes, Specialized focused on delivering optimal performance for all cyclists.
The Tarmac SL8 Expert Di2 delivers exceptional performance with a full Ultegra Di2 groupset, C38 carbon tubeless ready wheelset, and an SL7 stem with Specialized Expert Shallow Drop alloy handlebars makes for an accessible performance-packed bike.
