Specialized's brand new Tarmac SL7 is here and it's already been kicking up quite the storm on the racing circuit, seeing Vincent Luis dominate at the ITU World Triathlon Championships in Hamburg on the S-Works SL7. The SL7 Expert may not be the very top-notch top of the range S-Works version but it still packs a punch and provides an impressive performance; with a new and improved design featuring more aerodynamic tube shaping, the SL7 Expert is a whole 33 seconds faster over 40km than it's previous model, the SL6. Taking weight into consideration, Specialized has made the new SL7 even lighter than before with their FACT 10r carbon frame weighing just 920grams, meaning this new Tarmac Expert isn't just aero, it's super light in weight as well. The Tarmac SL7 truly has no weakness being a lightweight and aerodynmic road bike, allowing you to fly up the most grueling of climbs whilst also swiftly descending and cutting through the strongest of headwind stretches. To achieve this high performance design, Specialized took every UCI rule to the absolute limit to find the best possible result they could, bringing you a racing machine in it's truest form. When designing the new Tarmac, Specialized decided to use the most desirable features their very own Venge has to offer and transfer these across into their Tarmac, bringing a more aggressive and effective overall FreeFoil design. To ensure the SL7 frame maintained it's rigidity, Specialized increased the stiffness in other areas to provide and offer you a more efficient power transfer. Although the Tarmac has been built as a pure racing machine, Specialized didn't want to completely sacrifice your comfort and so their Rider-First Engineered™ technology and layup ensure's you'll find a set-up that's not only comfortable but provides top quality handling as well. And finally, to finish off a truly stunning bike, Specialized equipped this Expert with Roval C 38 wheels and a Shimano groupset for reliable riding and crisp shifting all ride long.
Faster & More Aerodynamic
"Aero is everything”- Specailized has been preaching it for years and it’s still the driving force for the new Tarmac. In their 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 their FreeFoil Shape Library. Armed with a library of optimized shapes, they 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 Specilized has tested—33 seconds faster over 40km than the Tarmac SL6. No compromises, just pure speed.
Super Light In Weight
While aerodynamics were paramount to the Tarmac’s development, and to the development of all of Specialized's 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, Specialized's 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 920 grams, without giving up a gram of aero, stiffness or ride quality.
The Perfect Race Bike
Continuing their quest to develop the perfect race bike, Specialized used their Rider-First Engineered™ philosophy to ensure that the new Tarmac is the most balanced, best handling Tarmac yet—no matter the size. With an army of the world’s best test riders from Specialized's three World Tour Teams — Boels-Dolmans, Deceuninck-Quick-Step, and Bora-hansgrohe — they made changes to the Tarmac based on their thousands of kilometers on the road. Specailized balanced the ride quality between the front and rear end, so even the longest days in the saddle continue to be comfortable—all without giving up anything to the Tarmac’s legendary handling and race-winning snappiness.
