For sale is a nearly new demo bike that has been ridden little (approximately 400 km). Some highlights of this custom bike include: - Ceramicspeed bottom bracket - Ceramicspeed Alpha Cage - 172.5 mm cranks with Power Meter - Cockpit 110x400 mm The S-Works Tarmac SL8 frame set is unmatched in speed. Its advanced aerodynamics and lightweight construction provide a riding experience that once seemed unattainable. After eight generations and over twenty years of development, it is not only the fastest Tarmac ever created, but it is also the fastest road bike in the world. Are you ready? Aerodynamics and low weight alone do not win races; speed is what counts at the finish line. To achieve race speed, a specific balance of aerodynamics, lightness, stiffness, and compliance is essential. Our Ride Science team has discovered through race simulations based on real data that the Tarmac SL8 is the fastest road bike ever built on critical courses, recording 16.6 seconds faster over 40 km, 128 seconds faster in the Milano-Sanremo, and 20 seconds quicker on the Tourmalet. AERO-AVANTGARDE: In our perspective, aerodynamics are about 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 head tube of the Tarmac SL8 maintains airflow better, as the front surface tapers to a sharper point. We call it the Speed Sniffer, and this streamlined cross-section of the head tube creates significantly less air resistance. Furthermore, in accordance with the new UCI regulations, we have developed the narrowest and most aerodynamic Specialized seat post ever for the Tarmac SL8, allowing the fast-moving turbulent air around the legs to disperse cleanly. A bike designed with a sense of victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 leverages insights from the development of the Aethos and easily meets the UCI weight limit, even with a complete aero setup. Our team has created an incredible frame weighing 685 grams, which is 15% lighter than the Tarmac SL7 and lighter than any other bike on the World Tour. It's worth mentioning that Kasper Asgreen rode our Aethos, which has a frame weight of just 585 grams, but that doesn't quite compare. The new technical possibilities have enabled us to optimize the weight of the down tube, seat tube, and rear end of the Tarmac, as the new frame shape distributes loads so efficiently that additional carbon layers for increased stiffness are no longer necessary.
