The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design deliver a ride quality that once seemed unattainable. After eight generations and over twenty years of development, it’s not just the fastest Tarmac ever made – it's the fastest road bike in the world. Are you ready? Aero Avantgarde: For us, the surfaces that truly matter are those that affect performance, not merely aesthetics. With this philosophy, we have created our most aerodynamic racing bike to date. Yes, it's more aerodynamic than the Venge. The redesigned head tube of the Tarmac SL8 maintains airflow better, featuring a sharper front surface. We call it the Speed Sniffer, and it significantly reduces drag with its streamlined cross-section. Additionally, we developed the narrowest and most aerodynamic Specialized seatpost ever for the Tarmac SL8, allowing turbulent air to flow cleanly around the legs. This bike has a keen sense for victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 benefits from insights gained during the development of the Aethos and easily meets the UCI weight limit, even with a full aero setup. Our team crafted an incredible frame weighing just 685 grams – 15% lighter than the Tarmac SL7 and lighter than any other bikes in the World Tour. While Kasper Asgreen raced the Aethos, with a frame that weighs only 585 grams, it doesn’t quite compare. The new technical possibilities enabled us to optimize the weight of the down tube, seat tube, and rear end of the Tarmac, as the new frame shape distributes load so efficiently that additional carbon layers for increased stiffness are unnecessary. LIGHTNING-FAST ACCELERATION WITH MORE COMFORT: Thanks to an incredible 33% improvement in the stiffness-to-weight ratio compared to the SL7, the Tarmac SL8 elevates its legendary handling, aggressive responsiveness, and World Tour-proven geometry to new heights. The bike is stiffer at the bottom bracket, more precise at the handlebars, and more forgiving at the saddle, setting new standards for performance and comfort in competitive bikes. Our Rider-First Engineering™ concept ensures that all riders, regardless of size, enjoy the same ride quality and handling. At the saddle, the Tarmac SL8 offers 6% more compliance. It glides smoothly over rough roads – a unique trait in the highly charged world of road cycling. Additionally, should conditions require it, 32 mm tire clearance allows for the use of wider tires.
