For sale is a nearly new demo bike with minimal usage (approximately 400 km). Some highlights of this custom bike include: - Ceramicspeed bottom bracket - Ceramicspeed Alpha Cage - 172.5 mm cranks with PowerMeter - Cockpit measuring 110x400mm The S-Works Tarmac SL8 frameset is unbeatable in speed. Its advanced aerodynamics and low weight combine to create a ride quality that seems 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 – what matters is speed at the finish line. To achieve race speed, a precise balance of aerodynamics, lightness, stiffness, and compliance is essential. Our Ride Science team has determined through race simulations with real data that the Tarmac SL8 is the fastest road bike ever built on the key segments. It is 16.6 seconds faster over 40 km, 128 seconds quicker in Milano–Sanremo, and 20 seconds faster on the Tourmalet. AERO-AVANTGARDE: To us, aerodynamics are about the surfaces that truly matter, not just those that look good. With this philosophy, we have created our most aerodynamic road bike ever. Yes, it is more aerodynamic than the Venge. The newly designed headtube of the Tarmac SL8 better maintains airflow, as its front surface tapers more sharply. We refer to it as the Speed Sniffer, and its streamlined headtube cross-section produces significantly less air resistance. Additionally, in line with the new UCI regulations for the Tarmac SL8, we developed the narrowest and most aerodynamic Specialized seatpost ever, allowing turbulent air to flow cleanly around the legs. A bike that has a sense of victory. MINIMUM WEIGHT, MAXIMUM AERO: The Tarmac SL8 leverages insights from the Aethos development, easily reaching 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 bike. The fact that Kasper Asgreen rode our Aethos, with a frame weight of only 585 grams, doesn’t really count. New technical possibilities enabled us to optimize the weight of the down tube, seat tube, and rear end of the Tarmac; the new frame shape distributes loads so efficiently that additional carbon layers for increased stiffness are no longer necessary.
