2021 Specialized S-Works Tarmac SL7 Frameset is the perfect canvas to begin your dream build. Build your totally-custom dream bike, and be ready to ride fast.
- “Aero is everything”—Specialized have been preaching it for years and it’s still the driving force for the new Tarmac. In a quest for tube shapes that deliver the fastest frame that the UCI rules allow, Specialized took a page out of the Venge development book and utilized there FreeFoil Shape Library. Armed with a library of optimized shapes, Specialized turned to the Win Tunnel to plug these shapes into a modular test bike, for more testing and validation. The result? A new Tarmac that’s the fastest ever tested—45 seconds faster over 40km than the Tarmac SL6 (built with Aerofly II handlebars, sold separately).
- While aerodynamics were paramount to the Tarmac’s development, and to the development of all Specialized race bikes, weight was the co-pilot on this optimal race bike journey. Previously “aero bikes” always compromised in the weight department—the more drag you reduced, the more weight you gained. With the new Tarmac, the design philosophy was to keep it at, or below, the UCI weight limit out of the box, with no sacrifices to aerodynamics. And with the help of the FreeFoil Shape Library, tools like isotopic FEA analysis, and some engineering wizardry by the best engineers in the industry, Specialized delivered a frame that weighs a mere 800 grams, without giving up a gram of aero, stiffness or ride quality.
- Continuing Specialized quest to develop the perfect race bike, Rider-First Engineered™ philosophy was used to ensure that the new Tarmac is the most balanced, best handling Tarmac yet.
