Its advanced aerodynamics and light weight contribute to a riding experience that seemed unattainable. After eight generations and more than twenty years of development, it is not just the fastest Tarmac ever created - it is the fastest racing bike in the world. Are you ready? Aerodynamics and low weight alone do not determine races; crossing the finish line depends on speed. Achieving race speed requires a specific balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has conducted race simulations using real data and found that the Tarmac SL8 is the fastest racing bike ever built on critical routes, being 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 comes from surfaces that truly count, not just those that look the best. With this philosophy, we created our most aerodynamic racing bike to date. Yes, it is more aerodynamic than the Venge. The newly designed head tube of the Tarmac SL8 maintains airflow better, as the front surface tapers more sharply. We refer to it as the Speed Sniffer, and its streamlined cross-section reduces drag significantly. Moreover, in line with the new UCI rules for the Tarmac SL8, we developed the narrowest and most aerodynamic Specialized seat post ever, allowing turbulent air moving around the legs to dissipate cleanly. A bike with a knack for winning. MINIMAL WEIGHT, MAXIMAL AERO: The Tarmac SL8 leverages insights from the development of the Aethos and easily meets the UCI weight limit, even with a full aero setup. Our team has created an incredible frame weighing just 685 grams - 15% lighter than the Tarmac SL7 and lighter than all other World Tour bikes. The fact that Kasper Asgreen rode our Aethos, whose frame weighs 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 load so efficiently that additional carbon layers for increased stiffness are no longer necessary.
