With the Tarmac SL8, Specialized has strategically integrated aerodynamic features in areas of maximum impact. Their meticulous approach has led to the creation of our most aerodynamically efficient road bike to date, surpassing even the previous Specialized Venge model in aerodynamic performance. The design focuses on optimizing clean airflow through the introduction of the Tarmac's innovative front-end structure: the Speed Sniffer nose cone. By repositioning the steer tube, which determines the head tube's width, they have achieved a significantly sharper leading edge for the head tube. This results in a remarkable reduction in aerodynamic drag. The Tarmac SL8 incorporates the slimmest and most aerodynamically advanced seat post ever designed, enhancing airflow around the rider's legs for improved aerodynamics.

Leveraging insights gained from the Aethos model, the Tarmac SL8 is engineered for effortless UCI-compliant assembly with a comprehensive aerodynamic configuration. The Specialized engineering team accomplished an impressive feat with an astonishingly lightweight frame weighing just 685 grams. This represents a remarkable 15% weight reduction compared to the Tarmac SL7. Drawing lessons from the Aethos project, Specialized prioritized weight reduction in critical areas like the down tube, seat tube, and rear of the bike. The SL8 frame achieves exceptional load distribution efficiency, rendering extra carbon stiffness layers unnecessary.

Boasting a substantial improvement in stiffness-to-weight ratio—an impressive 33% increase over the SL7—the Tarmac SL8 not only maintains its renowned handling characteristics and aggressive responsiveness but takes these attributes to an unprecedented level. The bike demonstrates heightened rigidity at the pedals and enhanced precision at the handlebars for exceptional steering control. This performance seamlessly blends with a compliant riding experience, setting a new standard for comfort in competitive road cycling. Specialized's Rider-First Engineering approach ensures that riders of all sizes enjoy the same exceptional ride quality and handling prowess. When seated, the Tarmac SL8 offers a notable 6% increase in compliance, smoothly gliding over uneven road surfaces with unmatched suppleness, a rare trait in the dynamic realm of race-oriented bikes. While retaining the proven geometry and accommodating the 32mm tire clearance of the SL7 model, the Tarmac SL8 maintains its adaptability and the flexibility to accommodate wider and higher-volume tires.

This Tarmac SL8 Pro is equipped with Shimano's Ultegra R8170 Di2, carbon wheelset and handlebars, bringing the performance of this Pro level bike to a level beyond. Return to Top
