Specialized Tarmac SL8 Comp

The Specialized Tarmac SL8 with SRAM Rival AXS groupset represents direct access to the fastest racing platform ever developed by Specialized. Derived directly from the S-Works version, this bike maintains the same design concept: to unite aerodynamics, lightness, and ride quality into a single solution capable of being fast on any route.

The FACT 10r carbon Tarmac SL8 frame is designed according to the Rider First Engineered™ philosophy, which optimizes stiffness, weight, and dynamic behavior for each individual size. The frame structure originates from aerodynamic studies in the Specialized Win Tunnel and fully integrates the cables, offering a clean design and reduced air resistance.

The Tarmac SL8 is considered the fastest road bike in the world because it is not based on a single parameter. Speed stems from the balance between aerodynamics, reduced weight, stiffness, and comfort. Simulations by the Ride Science Team have demonstrated concrete advantages on real routes: faster on flat terrain, in classics, and even on major climbs.

Aerodynamics have been optimized in the frontal zone, with a design of the steerer tube and fork engineered to reduce air resistance. The slim, profiled seatpost further improves aerodynamic flow in the leg area, increasing efficiency at high speeds.

The frame maintains the proven racing geometry of the Tarmac, with clearance for tires up to 32 mm, ensuring precise handling, comfort, and great versatility on different types of asphalt.

This version is equipped with the new 12-speed SRAM Rival AXS electronic groupset, which provides precise shifting, powerful braking, and simple, intuitive operation. The DT Swiss R470 tubeless-ready wheels and the Specialized cockpit complete a balanced and high-performance setup, designed for those who want a true race bike with an excellent price-to-performance ratio.
