The 2025 Specialized S-Works Tarmac SL8 Shimano Dura-Ace Di2 Road Bike is the fastest Tarmac ever thanks to a combination of aerodynamics, lightweight, and ride quality previously thought impossible.
Aerodynamics or lightweight alone don’t win races, speed is what matters. Delivering that speed requires creating an uncompromising combination of aerodynamics, lightweight, stiffness, and compliance. Through race simulations using real world data Specialized's Ride Science team knows the Tarmac SL8 is the fastest race bike ever made on the routes that matter. It's 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.
Utilizing new UCI rules, the Tarmac SL8 has the narrowest, most aero seat post we’ve ever made ensuring fast moving, dirty air around the legs can flow back more cleanly. Tarmac SL8 took learnings from Aethos to be easily built at the UCI minimum with a full aero set up - 15% lighter than the Tarmac SL7. The bike is stiffer at the pedals, more precise at the bars, and combines it with a compliant ride in the saddle that sets a new benchmark for race bike comfort.
The S-Works Tarmac SL8 comes with only the best components. A full Shimano Dura-Ace 9200 series Di2 groupset with dual-sided power meter, and a Roval Rapide CLX II tubeless-ready wheelset is the perfect complement to the world’s fastest frame. All S-Works Tarmac SL8 models ship with a Roval Rapide cockpit to save weight and for the fastest possible leading edge.
This bike is perfect for
Road racers who need pro level performance. With the Tarmac SL 8 you get all the latest aero tech, power meter, and electronic gearing all wrapped up in a lightweight package.
