SPECIALIZED S-WORKS TARMAC SL8 SHIMANO DURA-ACE DI2 BIKE

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 road bike in the world. Are your legs ready?

Aerodynamics or lightness alone don’t win races; what matters is speed. To achieve this speed, it’s necessary to create a no-compromise combination of aerodynamics, lightness, stiffness, and compliance. Through complex simulations using real-world data, our Ride Science Team has confirmed that the Tarmac SL8 is the fastest road bike on any course: - 16.6 seconds faster over 40 km on flat terrain, 128 seconds faster on the Milan-Sanremo course, and 20 seconds faster on the Tourmalet climb.

SPECIALIZED S-WORKS TARMAC SL8 SHIMANO DURA-ACE DI2 BIKEMAIN FEATURES:

• AERODYNAMICS: We use aerodynamics where it matters most, and in the process, we’ve 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, significantly reducing aerodynamic drag. Thanks to new UCI regulations, we were able to design the SL8 with the narrowest and most aerodynamic seatpost we’ve ever made, ensuring that turbulent air around the rider’s legs flows more easily toward the rear of the bike.
• LIGHTNESS: To create the Tarmac SL8 and build the most aerodynamic bike while respecting the UCI’s minimum weight requirements, we drew inspiration from what we learned with the Aethos. The team produced a frame weighing just 685 grams—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 end of the bike, we applied the lessons learned from the Aethos project. The frame shapes respond so efficiently to loads that we were able to reduce material thickness, eliminating the superfluous. *Except for that one time when Kasper Asgreen raced with 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’s precise in the most demanding situations and responds immediately and efficiently to pedal inputs. While the areas ensuring power transfer and precise steering are stiffer than ever, the Tarmac SL8 is more comfortable, filtering out 6% more road vibrations and allowing you to attack corners with an agility and balance unmatched in the world of road racing bikes. The new Tarmac SL8 retains the proven geometry of the SL7, with the same generous clearance for 32 mm tires, so you can use larger-volume tires 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: Don’t create differences where there are none. Every cyclist, regardless of gender, can benefit from the advantages of the Tarmac SL8. It’s time to move beyond.
  The S-Works Tarmac SL8 is equipped with the Shimano Dura-Ace Di2 9200 series groupset with dual-sided powermeter, Roval Rapide CLX II tubeless ready wheels, and Roval Rapide cockpit.
