Its advanced aerodynamics combined with low weight offer a ride quality that seemed unattainable. After eight generations and over twenty years of development, it is not just the fastest Tarmac ever – it is the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not win races; it is speed that counts at the finish line. Achieving race speed requires a specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has discovered through racing simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on crucial segments. It is 16.6 seconds faster over 40 km, 128 seconds faster in the Milano–Sanremo, and 20 seconds faster on the Tourmalet. AERO-AVANTGARDE: For us, aerodynamics are all about the surfaces that truly matter, rather than those that simply look good. With this philosophy, we have created our most aerodynamic road bike to date. Yes, it is more aerodynamic than the Venge. The redesigned head tube of the Tarmac SL8 maintains airflow more effectively, as the surface at the front tapers sharper. We call it the Speed Sniffer, and its streamlined cross-section generates much less air resistance. Moreover, in accordance with the new UCI rules for the Tarmac SL8, we have developed the narrowest and most aerodynamic Specialized seat post ever. This allows the rapidly moving turbulent air around the legs to flow away more cleanly. A bike with a feel for victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 utilizes insights gained from the development of the Aethos and easily meets the UCI weight limit, all with a complete aero setup. Our team has developed an incredible frame weighing 685 grams – 15% lighter than the Tarmac SL7 and lighter than any other bike in the World Tour. That Kasper Asgreen rode our Aethos on a tour stage, with a frame weighing just 585 grams, doesn’t quite 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 more stiffness are no longer necessary.
