Its advanced aerodynamics and lightweight design result in a ride quality that 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 – it all comes down to 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, in key segments, the fastest road bike ever created. It is 16.6 seconds faster over 40 km, 128 seconds quicker on Milano-Sanremo, and 20 seconds faster on the Tourmalet. AERO-AVANTGARDE: For us, the surfaces that truly matter in aerodynamics are not those that simply look best. With this philosophy, we've created our most aerodynamic road bike ever. 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 to a sharper point. We call it the Speed Sniffer, and its streamlined cross-section results in significantly less air resistance. Additionally, compliant with the new UCI regulations for the Tarmac SL8, we've developed the narrowest and most aerodynamic Specialized seatpost to date, allowing turbulent air to flow cleanly around the legs. A bike with a flair for victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 incorporates insights from developing the Aethos, easily adhering to the UCI weight limit 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 World Tour bikes. Although Kasper Asgreen rode our Aethos, which has a frame weight of only 585 grams, that doesn't quite count. New technical possibilities empowered us to optimize the weight of the down tube, seat tube, and rear, as the new frame shape distributes loads so efficiently that additional carbon layers for increased stiffness are no longer necessary.
