S-Works Tarmac SL8 Shimano Dura-Ace Di2 – The Ultimate Aero Road Race Bike
Dominate the road with the S-Works Tarmac SL8 Shimano Dura-Ace Di2, the world’s fastest road bike. Designed for elite racers and performance-focused cyclists, this aero road bike combines cutting-edge aerodynamics, ultra-lightweight carbon construction, and world-class ride quality. After eight generations and over 20 years of development, the Tarmac SL8 sets a new benchmark in road cycling performance.
Unmatched Speed and Aerodynamics
The Tarmac SL8 is engineered to maximise speed through a perfect balance of aero efficiency, stiffness, light weight, and compliance. Real-world simulations show it is 16.6 seconds faster over 40km, 128 seconds quicker at Milan-San Remo, and 20 seconds ahead on the Tourmalet climb compared to previous models. Specialized’s new Speed Sniffer head tube and narrow, aerodynamic seat post improve airflow and reduce drag for the fastest possible ride.
Lightweight Design
Inspired by the Aethos, the Tarmac SL8 frame weighs just 685g, 15% lighter than the SL7 and lighter than any World Tour bike. Optimised carbon layup eliminates unnecessary weight without compromising stiffness or durability, creating a bike that is fast, responsive, and race-ready.
World-Class Ride Quality
With 33% improved stiffness-to-weight ratio, the Tarmac SL8 delivers precise handling, efficient power transfer, and Rider-First Engineering ensures consistent ride quality across all frame sizes. The frame offers 6% more compliance for a smoother ride over rough roads, while maintaining the proven geometry and 32mm tyre clearance for versatility.
Performance Components
The S-Works Tarmac SL8 comes fully equipped with the Shimano Dura-Ace 9200 Di2 electronic groupset, complete with a dual-sided power meter for precision training. Paired with Roval Rapide CLX II tubeless-ready wheels and a Roval Rapide cockpit, this bike is optimized for maximum aerodynamics, lightweight performance, and road racing efficiency.
