The Tarmac SL8 frameset is constructed of FACT 10R carbon which offers a perfect balance of performance and compliance. The frameset includes frame, fork, carbon seatpost and headset.

With the Tarmac SL8, Specialized has strategically incorporated aerodynamic features where they hold the greatest impact. Their meticulous approach has resulted in the development of our most aerodynamically efficient road bike to date, surpassing even the former Specialized Venge model in aerodynamic prowess. The design optimizes clean airflow with the introduction of the Tarmac's innovative front-end structure: the Speed Sniffer nose cone. By repositioning the steer tube, which dictates the width of the head tube, they have achieved a significantly sharper leading edge for the head tube, resulting in remarkably reduced aerodynamic drag. The Tarmac SL8 integrates the slimmest, most aerodynamically advanced seat post ever designed, enhancing the flow of turbulent air around the rider's legs for improved aerodynamic performance.

Drawing from the insights gained from the Aethos model, the Tarmac SL8 has been engineered for effortless UCI-compliant assembly with a comprehensive aerodynamic configuration. The Specialized engineering team achieved a remarkable feat; an astonishingly lightweight frame weighing in at a mere 685 grams. This represents a staggering 15% reduction in weight compared to the Tarmac SL7. Implementing lessons learned from the Aethos project, Specialized prioritized weight reduction in critical areas such as the down tube, seat tube, and rear of the bike. The SL8 frame has exceptional load distribution efficiency, rendering additional carbon stiffness layers superfluous.... Read More
