The 2025 Specialized S-Works Tarmac SL8 SRAM RED AXS Road Bike delivers speed through 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 - 16.6 seconds faster over 40km, 128 seconds faster over Milan San Remo, 20 seconds faster over the legendary Tourmalet climb.
The Tarmac SL8 took learnings from the Specialized Aethos to be easily built at the UCI minimum with a full aero set up. The team delivered a mind bending, scale tickling 685 gram frame - 15% lighter than the Tarmac SL7 and lighter than anything on else on the World Tour. Clean air is optimized for maximum advantage with the Tarmac’s new nose cone - the Speed Sniffer. By moving the steer tube back - the tube that determines head tube width - the leading edge of the head tube can be much sharper, delivering a much lower drag shape.
The S-Works Tarmac SL8 is spec’d with only the best components. A full SRAM RED AXS groupset with power meter - the lightest electronic groupset ever - and a Roval Rapide CLX II tubeless-ready wheelset are 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 want the best combination of lightweight and aero performance. Built to be fast in the real world and win World Tour stages.
