Its advanced aerodynamics and lightweight design create a riding experience that seemed unattainable. After eight generations and over twenty years of development, it is not just the fastest Tarmac ever made – it is the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone don’t win races – it’s 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 using real-world data that the Tarmac SL8 is the fastest road bike ever built on critical courses, recording 16.6 seconds faster over 40 km, 128 seconds quicker at Milano-Sanremo, and 20 seconds quicker on the Tourmalet. AERO-AVANTGARDE: For us, aerodynamics come from surfaces that truly matter, not just those that look good. With this philosophy, we have created our most aerodynamic road bike to date. And yes, it is more aerodynamic than the Venge. The newly designed head tube of the Tarmac SL8 maintains airflow better as its front surface tapers more sharply. We call it the Speed Sniffer, and with it, the streamlined profile of the head tube creates significantly less drag. Additionally, in accordance with the new UCI regulations for the Tarmac SL8, we have developed the narrowest and most aerodynamic Specialized seat post ever. This allows the fast-moving disturbed air around the legs to exit more cleanly. A bike with a winning edge. MINIMAL WEIGHT, MAXIMAL AERO: The Tarmac SL8 leverages insights from the Aethos development to easily meet the UCI weight limit, even with 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. While Kasper Asgreen raced our Aethos, which has a frame weight of just 585 grams, this fact is somewhat irrelevant. The new technical possibilities allowed us to optimize the weight of the down tube, seat tube, and rear end of the Tarmac, as the new frame shape distributes load so efficiently that additional carbon layers for added stiffness are no longer necessary.
