Specialized Tarmac SL8 Pro Etap SRAM Force eTap AXS

The fastest racing bike in the world!

No bike is as fast as the Tarmac SL8 thanks to a combination of aerodynamics, lightness and ride quality previously thought impossible. After eight generations and over two decades of development, it is not only the fastest Tarmac ever: it is the fastest road bike in the world. Are your legs ready? Aerodynamics or lightness alone do not win races: what matters is speed. Achieving this speed requires an uncompromising combination of aerodynamics, lightness, stiffness and stress absorption. Thanks to complex simulations using real-world data, the Ride Science Team has verified that the Tarmac SL8 is the fastest race bike on any course: - 16.6 seconds on 40km of flat terrain, 128 seconds faster on the Milan-San Remo course, 20 seconds faster on the Tourmalet climb.

Aerodynamics
Specialized uses aerodynamics where it's needed most, and in the process created the fastest road bike ever - yes, more aerodynamic than even the Venge. The front end has been optimised for maximum benefit. The fork steerer is positioned to the rear of the front of the frame head tube to offer much lower aerodynamic drag. Thanks to new UCI rules, for the SL8 Specialized was able to use the narrowest and most aerodynamic seatpost Specialized has ever made, to ensure that turbulent air in the leg area can flow more easily to the rear of the bike.

Lightness
To create the Tarmac SL8 and build the most aerodynamic bike while meeting UCI's minimum weight requirements, the Specialized team was inspired by what Specialized learned with the Aethos. The team created a 685 gram frame, 15% lighter than the Tarmac SL7 and lighter than any other World Tour bike*. Focusing on maximum possible lightness in the down tube, seat tube and rear of the bike, Specialized adopted the lessons learned in the Aethos project. The frame shapes respond so efficiently to stresses that it was possible to reduce the thickness of the material, eliminating the superfluous. Except for the time when Kasper Asgreen raced with the 585 gram Aethos frame during a stage of the Tour.

Ride quality
The stiffness-to-weight ratio of the Tarmac SL8 is 33% better than that of the SL7. The Tarmac SL8 sets a new benchmark in handling: it is precise in the most demanding situations and responds immediately and efficiently to pedal inputs. While the areas that ensure power transfer and steering precision are stiffer than ever, in the saddle the Tarmac SL8 is more comfortable, filtering 6% more stress from the terrain and allowing you to attack corners with a feeling of agility and balance unique in the world of road bikes. The new Tarmac SL8 retains the tried and tested geometry of the SL7 model, with the same generous 32mm tyre clearance so that more volume can be used when needed.

Beyond gender differences
In reality, there can be many more differences between two male cyclists than between a man and a woman. Specialized designs according to the individual and the philosophy is simple: Don't create differences where there are none. Every cyclist, male or female, can benefit from the advantages of the Tarmac SL8. It's time to go further. The Tarmac SL8 Pro is fitted with the SRAM Force eTap AXS groupset with powermeter, Roval Rapide CL II tubeless ready wheels, SL7 stem with Roval Rapide handlebar: race ready.
