SPECIALIZED S-Works Tarmac SL8 Di2 Gloss Solidity Red My25

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’s not just the fastest Tarmac ever: it’s the fastest racing bike in the world. Are your legs ready?

Aerodynamics or lightness alone do not win the races: what counts is speed. To achieve this speed, it is necessary to create a combination of aerodynamics, lightness, stiffness and stress absorption without compromise. Thanks to complex simulations using real data, our Ride Science Team has verified that the Tarmac SL8 is the fastest racing bike on any route: - 16.6 seconds over 40 km of plain, 128 seconds faster on the Milano-CorsaSanremo, 20 seconds faster on the ascent of the Tourmalet.

AERODYNAMICS: We use aerodynamics where it’s most needed, and in the process we’ve created our fastest road bike ever - yes, more aerodynamics than the Venge. The front has been optimized to get the maximum advantage. The fork rail is positioned at the rear of the front of the steering tube to provide much lower drag. Thanks to the new UCI rules, we were able to use the narrowest and most aerodynamic seat post we have ever made for the SL8, to ensure that turbulent air in the leg area can flow more easily towards the rear of the bike.
LIGHTNESS: To create the Tarmac SL8 and make the most aerodynamic bike, respecting the minimum weight requirements imposed by UCI we were inspired by what we learned with the Aethos. The team has created a 685 gram frame, 15% lighter than the Tarmac SL7 and lighter than any other bike on the World Tour*. Focusing on maximum lightness in the area of the slanting tube, the seat tube and the rear of the bike, we have adopted the lessons learned from the Aethos project. The frame shapes respond so efficiently to stresses that it has been possible to reduce the thickness of the material, eliminating the superfluous. *Except for the time when Kasper Asgreen ran our 585 gram Aethos chassis during one stage of the Tour.
DRIVING QUALITY: The stiffness-weight ratio of the Tarmac SL8 is 33% better than the SL7. The Tarmac SL8 sets a new benchmark for handling: it is precise in the most demanding situations and responds immediately and efficiently to inputs on the pedal. While the areas that ensure power transfer and driving precision are stiffer than ever, riding the Tarmac SL8 is more comfortable, filtering 6% more of the stresses coming from the ground and allowing to attack the curves with a feeling of agility and balance unique in the world of racing bikes. The new Tarmac SL8 maintains the proven geometry of the SL7, with the same generous 32 mm tyre space so you can use a larger tread when needed.

BEYOND GENDER: In reality there can be much more differences between two male cyclists than between a man and a woman. We design based on the individual and our philosophy is simple: Do not create differences where there are none. Every cyclist, male or female, can take advantage of the benefits of the Tarmac SL8. It’s time to go further.
L’S-Works Tarmac SL8 mounts the Shimano Dura Ace Di2 9200 series with powermeter on both sides, Roval Rapide CLX II tubeless ready wheels, Roval Rapide cockpit.
'Apple Find My' technology is now integrated in all SW & Pro 4iiii power meters. Riders can now enjoy the peace of mind that comes with knowing the exact location of their bikes.
