This custom bike is equipped with the following components: - Complete Sram Red AXS drivetrain - Crank length of 172.5mm - Roval Rapide cockpit 110x400mm The S-Works Tarmac SL8 frame set is unbeatable in speed. Its advanced aerodynamics combined with a lightweight design provide a riding 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 don't win races – it’s all about speed at the finish line. To reach race speed, a precise balance of aerodynamics, lightness, stiffness, and compliance is essential. Our Ride Science team has determined through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on key segments. It is a remarkable 16.6 seconds faster over 40 km, 128 seconds quicker in Milano–Sanremo, and 20 seconds swifter on the Tourmalet. AERO-AVANTGARDE: For us, it’s the surfaces that truly matter aerodynamically, not just the ones that look good. With this philosophy, we have created our most aerodynamic road bike ever. And yes, it is more aerodynamic than the Venge. The redesigned head tube of the Tarmac SL8 better maintains airflow, as the front surface tapers sharply. We call it the Speed Sniffer, and with it, the more streamlined shape of the head tube generates significantly less air resistance. In alignment with the new UCI regulations, we have also developed the narrowest and most aerodynamic Specialized seat post to date for the Tarmac SL8, allowing the rapidly moving turbulent air to flow cleanly around the legs. A bike designed for victory. MINIMAL WEIGHT, MAXIMAL AERO: The Tarmac SL8 incorporates insights from the Aethos development and easily meets the UCI weight limit with a complete aero setup. Our team has created an incredible frame weighing just 685 grams – 15% lighter than the Tarmac SL7 and lighter than any other bike on the World Tour. Although Kasper Asgreen rode our Aethos, which weighs only 585 grams, at a Tour stage, this comparison doesn’t count. The new technological possibilities enabled us to optimize the weight of the down tube, seat tube, and rear end, as the new frame shape distributes the load so efficiently that additional carbon layers for more stiffness are no longer necessary.
