With its advanced aerodynamics and light weight, it offers a riding quality that once seemed unattainable. After eight generations and more than twenty years of development, it is not only the fastest Tarmac ever made – it is 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 specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has determined through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on critical courses. It is a whole 16.6 seconds faster over 40 km, 128 seconds faster in the Milano-Sanremo, and 20 seconds faster on the Tourmalet. AERO-AVANTGARDE: Our approach to aerodynamics focuses on the surfaces that truly matter, not just those that look good. With this philosophy, we have created our most aerodynamic road bike to date. Yes, it is more aerodynamic than the Venge. The newly designed head tube of the Tarmac SL8 better maintains airflow, as the front surface tapers more sharply. We call this the Speed Sniffer, and it allows the streamlined cross-section of the head tube to create significantly less air resistance. Additionally, in accordance with the new UCI rules for the Tarmac SL8, we have developed the narrowest and most aerodynamic Specialized seatpost ever, enabling the rapidly moving turbulent air around the legs to flow cleanly. A bike with a sense for victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 leverages insights from the development of the Aethos and easily meets the UCI weight limit, while maintaining a complete aero setup. Our team has crafted an incredible frame weighing just 685 grams – 15% lighter than the Tarmac SL7 and lighter than any other bike in the World Tour. The fact that Kasper Asgreen rode our Aethos, which has a frame weight of only 585 grams, doesn't really count. The new technical possibilities enabled us to optimize the weight of the down tube, seat tube, and rear end of the Tarmac, as the new frame shape distributes the load so efficiently that additional carbon layers for extra stiffness are no longer necessary.
