Its advanced aerodynamics and light weight deliver a riding quality that once seemed unattainable. After eight generations and more than 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 do not determine races – at the finish line, speed is what matters. To achieve race speed, a specific balance of aerodynamics, lightness, stiffness, and compliance is required. Our Ride Science Team has discovered through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on crucial routes, finishing a remarkable 16.6 seconds faster over 40 km, 128 seconds quicker at Milano–Sanremo, and 20 seconds faster at the Tourmalet. AERO-AVANTGARDE: At our company, the surfaces that truly matter are those that impact aerodynamics, not just aesthetics. With this philosophy, we have created our most aerodynamic road bike ever. And yes, it is more aerodynamic than the Venge. The newly designed head tube of the Tarmac SL8 maintains airflow better, as the surface at the front tapers sharply. We call it the Speed Sniffer, and with it, the streamlined cross-section of the head tube creates significantly less drag. Additionally, in line with the new UCI rules, we have developed the narrowest and most aerodynamic Specialized seat post ever for the Tarmac SL8, allowing the fast-moving turbulent air to exit cleanly around the legs. A bike that has a feel for victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 leverages insights from the development of the Aethos and effortlessly meets the UCI weight limit, all while featuring a complete aero setup. Our team has crafted an incredible frame weighing 685 grams – 15% lighter than the Tarmac SL7 and lighter than all other bikes in the World Tour. Although it's noteworthy that Kasper Asgreen rode our Aethos on a Tour Stage, with a frame weight of only 585 grams, the new technical capabilities allowed us to optimize the weight of the down tube, seat tube, and rear end for the Tarmac, as the new frame shape distributes the load so efficiently that additional carbon layers for more stiffness are no longer necessary.
