Specialized S-Works Tarmac SL8 Di2

Aerodynamics or lightness alone do not win races: what matters is speed. To achieve this speed, it is necessary to create a no-compromise combination of aerodynamics, lightness, stiffness, and shock absorption. Through complex simulations using real data, our Ride Science Team has verified that the Tarmac SL8 is the fastest racing bike on any course: - 16.6 seconds faster over 40 km of flat terrain, 128 seconds faster on the Milano-Sanremo route, and 20 seconds faster on the Tourmalet climb.

AERODYNAMICS: We use aerodynamics where it is most needed, and in the process, we have created our fastest road bike ever – yes, even more aerodynamic than the Venge. The front end has been optimized for maximum advantage. The fork steerer is positioned rearward relative to the front of the frame’s head tube to provide much lower aerodynamic resistance. Thanks to new UCI rules, for the SL8 we were able to use the narrowest and most aerodynamic seatpost we have ever made, ensuring that turbulent air in the leg area can flow more easily to the rear of the bike.

LIGHTNESS: To create the Tarmac SL8 and achieve the most aerodynamic bike while meeting the UCI's minimum weight requirements, we drew inspiration from what we learned with the Aethos. The team produced a 685-gram frame, 15% lighter than the Tarmac SL7 and lighter than any other bike in the World Tour*. By focusing on maximum lightness in the downtube, seat tube, and rear of the bike, we applied the lessons learned from the Aethos project. The frame shapes respond so efficiently to stresses that we were able to reduce material thickness, eliminating the unnecessary. *Except for that one time when Kasper Asgreen rode our 585-gram Aethos frame during a Tour stage.

RIDE QUALITY: The stiffness-to-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 challenging situations and responds immediately and efficiently to pedal inputs. While the areas that ensure power transfer and steering precision are stiffer than ever, the Tarmac SL8 feels more comfortable in the saddle, filtering 6% more road vibrations and allowing for cornering with a unique sense of agility and balance in the world of racing bikes. The new Tarmac SL8 maintains the proven geometry of the SL7 model, with the same generous 32mm tire clearance, allowing for a larger volume tire when necessary.

BEYOND GENDER DIFFERENCES: In reality, there can be many 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 none exist. Every cyclist, whether male or female, can benefit from the advantages of the Tarmac SL8. It’s time to move beyond.

The S-Works Tarmac SL8 features the Shimano Dura Ace Di2 9200 series groupset with dual-sided powermeter, tubeless-ready Roval Rapide CLX II wheels, and Roval Rapide cockpit.
