Its advanced aerodynamics and lightweight design provide a riding experience that once seemed unattainable. After eight generations and more than twenty years of development, it’s not only the fastest Tarmac ever created – it’s the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not win races – it's all about speed at the finish line. Achieving race speed requires a precise balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team discovered through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on key stretches. It is a remarkable 16.6 seconds faster over 40 km, 128 seconds quicker at Milano–Sanremo, and 20 seconds faster on the Tourmalet. AERO-AVANTGARDE: For us, aerodynamics is about surfaces that truly matter, not just those that look good. With this philosophy, we created our most aerodynamic road bike ever. Yes, it is more aerodynamic than the Venge. The newly designed head tube of the Tarmac SL8 maintains airflow more effectively, as its front surface tapers to a point. We call it the Speed Sniffer, and with it, the streamlined cross-section of the head tube generates significantly less air resistance. Additionally, in accordance with the new UCI rules for the Tarmac SL8, we developed the narrowest and most aerodynamic Specialized seatpost ever, allowing the fast-moving turbulent air to exit cleanly around the legs. A bike designed with a sense for victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 utilizes insights from the development of the Aethos, easily reaching the UCI weight limit while maintaining a complete aero setup. Our team has designed an incredible frame weighing just 685 grams, which is 15% lighter than the Tarmac SL7 and lighter than any other World Tour bike. The fact that Kasper Asgreen rode our Aethos, which has a frame weight of only 585 grams, in a Tour stage somewhat doesn’t count. New technical possibilities enabled us to optimize the weight of the down tube, seat tube, and rear end on the Tarmac, as the new frame shape distributes the load so efficiently that additional carbon layers for increased stiffness are no longer necessary.
