The S-Works Tarmac SL8 is unbeatable in speed. Its advanced aerodynamics and lightweight design deliver a ride quality that once seemed out of reach. 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 Avant-Garde: For us, aerodynamics are defined by surfaces that truly matter, not just those that look good. With this philosophy, we have created our most aerodynamic road bike to date. And yes, it is more aerodynamic than the Venge. The newly designed head tube of the Tarmac SL8 maintains airflow more effectively thanks to its sharper front profile. We call it the Speed Sniffer, and this streamlined shape of the head tube creates significantly less air resistance. Furthermore, in line with new UCI regulations for the Tarmac SL8, we have developed the narrowest and most aerodynamic Specialized seat post ever, allowing turbulent air to cleanly flow around the legs. A bike that has a sense for victory. MINIMAL WEIGHT, MAXIMUM AERO: The Tarmac SL8 utilizes insights gained from the Aethos's development and easily meets the UCI weight limit with a complete aero setup. Our team has created an incredible frame weighing 685 grams – 15% lighter than the Tarmac SL7 and lighter than any other bike on the World Tour. The fact that Kasper Asgreen rode our Aethos, which has a frame weighing just 585 grams, during a tour stage doesn’t really count. These new technical possibilities enabled us to optimize the weight of the down tube, seat tube, and rear end, as the new frame shape distributes load so efficiently that additional carbon layers for increased stiffness are no longer necessary. LIGHTNING-FAST ACCELERATION WITH MORE COMFORT: Thanks to a remarkable improvement in the stiffness-to-weight ratio – an astonishing 33% over the SL7 – the Tarmac SL8 takes legendary handling, aggressive response, and World Tour-proven geometry to a whole new level. 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 every rider, regardless of size, enjoys the same ride quality and handling. At the saddle, the Tarmac SL8 offers 6% more compliance. It glides smoothly over rough roads – uniquely so in the high-stakes world of cycling. And when conditions call for it, thanks to the 32 mm tire clearance, tires with more volume can be used.
