The Tarmac SL8 Expert is unbeatable in speed. Its advanced aerodynamics and lightweight design deliver a riding experience previously thought unattainable. After eight generations and over twenty years of development, it’s not just the fastest Tarmac ever created – it’s the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone don’t win races; what matters at the finish line is speed. Achieving race speed requires a delicate balance of aerodynamics, lightness, stiffness, and compliance. Our Ride Science Team has conducted race simulations based on real data and determined that the Tarmac SL8 is the fastest road bike on critical courses ever built. It is 16.6 seconds faster over 40 km, 128 seconds quicker at Milano–Sanremo, and 20 seconds faster up the Tourmalet. AERO-AVANTGARDE: For us, aero means surfaces that truly matter, not just those that look good. With this philosophy, we’ve created our most aerodynamic road 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 to a sharper point. We refer to it as the Speed Sniffer, and its streamlined head tube shape generates significantly less air resistance. Furthermore, in line with the new UCI regulations, we’ve developed the narrowest and most aerodynamic Specialized seat post ever for the Tarmac SL8. This allows the fast-moving turbulent air to flow cleanly around the legs. A bike with a keen sense for victory. MINIMAL WEIGHT, MAXIMAL AERO: The Tarmac SL8 leverages insights from the development of the Aethos, easily reaching the UCI weight limit with a complete aero setup. Our team has engineered an incredible frame weighing just 685 grams – 15% lighter than the Tarmac SL7 and lighter than any other bikes in the World Tour. While Kasper Asgreen did ride our Aethos, which features a frame weighing only 585 grams, that’s an exception. Our new technical advancements enabled us to optimize the weight of the down tube, seat tube, and rear end, as the new frame shape distributes load so efficiently that additional carbon layers for increased stiffness are no longer necessary.
