Escapa presents the Specialized S-Works Tarmac SL8 Dura-Ace Di2 25 Bike, a bike for cyclists who love responsiveness, lightness, and aerodynamics—a bike built for sprinting and conquering mountain passes alike.
The Specialized S-Works Tarmac SL8 Dura-Ace Di2 25 is equipped with the best components. It comes with a complete Shimano Dura-Ace 9200 Di2 groupset featuring a dual-sided shifter and a set of Tubeless-compatible Roval Rapide CLX II wheels, which perfectly complement the world’s fastest frame. All S-Works Tarmac SL8 models also feature a Roval Rapide Cockpit, designed to reduce weight and provide the most aerodynamic leading edge possible.
Races aren’t won by aerodynamics or light weight alone—what matters is speed. And to achieve that, you need to create an uncompromising combination of aerodynamics, light weight, stiffness, and comfort. Our Ride Science team simulated races using real-world data and found that the Tarmac SL8 is the fastest road bike ever built on the most important routes: 16.6 seconds faster over 40 km, 128 seconds faster in the Milan–San Remo, and 20 seconds faster on the legendary Tourmalet climb.
100% AERO
With aerodynamic elements where they’re truly needed, not just where they look good. This has resulted in the most aerodynamic Tarmac yet. Yes, even more so than the Venge. With the Speed Sniffer—the Tarmac’s new head tube—clean air is optimized to deliver the maximum advantage. By moving the head tube back (which determines the head tube angle), the leading edge of the head tube becomes much sharper, and the resulting shape creates significantly less aerodynamic drag. Taking advantage of the new UCI rules, the Tarmac SL8 features the narrowest and most aerodynamic seatpost ever manufactured. This allows the turbulent air around the rider’s legs to flow more smoothly toward the rear.
MINIMUM WEIGHT, MAXIMUM AERODYNAMICS
Thanks to lessons learned from the Aethos, the Tarmac SL8 has been designed to meet the UCI’s minimum requirements while offering a 100% aero build. The team has created an incredible 685-gram frame—15% lighter than the Tarmac SL7 and lighter than any other frame on the World Tour*. We’ve also applied what we learned from the Aethos to prioritize lightness in the down tube, seat tube, and rear end of the bike. The frame’s shape supports the load so efficiently that there’s no need to add extra layers of carbon.
IT FLIES LIKE A ROCKET, RIDES LIKE A DREAM
With an optimized stiffness-to-weight ratio (33% better than the SL7), the Tarmac SL8 delivers legendary ride quality, aggressive responsiveness, and world-championship-proven geometry that’s in a league of its own. The bike is stiffer at the pedals, more precise at the handlebars, and more comfortable in the saddle—so much so that it sets a new standard for comfort in road bikes. Thanks to Rider-First Engineering, all riders, regardless of size, can enjoy a level of ride quality and control never seen before. In the saddle, the Tarmac SL8 offers 6% more comfort: it glides over uneven terrain and delivers a smoothness that’s rare in the demanding world of road bikes. The Tarmac’s geometry and 32 mm tire clearance are identical to those of the SL7, ensuring an easy transition and the option to use larger tires when needed.
BEYOND GENDER
Gender alone doesn’t provide enough data to be the sole factor in bike design. That’s why creating bikes exclusively for men or women is a thing of the past. All riders can enjoy the benefits of the Tarmac SL8.
