For the construction, Specialized utilized advanced aerospace composite optimization software to revolutionize the development and layup of their new FACT 12r carbon. It's the most advanced material they've ever made. This sheds nearly 200 grams off previous year models. That's right, a 20% reduction in frame weight—the perfect recipe for your next hill climb PR.
Specialized also took significant steps to improve their Rider-First Engineered™ technology to ensure that the new Tarmac is stiff and compliant in precisely the right places. From different layup schedules and materials, to visibly different forks, Specialized scrutinized every single aspect of the new Tarmac to ensure you're getting the perfect ride. With this revamp, they also updated the geometry, basing it on countless Retül data points and professional rider input. This enabled the development of a Performance Road Geometry that perfects the combination of a responsive front-end and short wheelbase, which delivers instantaneous response and optimal power transfer.
And while stiffness aids in the aforementioned, compliance must also be utilized for optimal ride quality. That's why Specialized designed a seatpost that builds compliance into the upper 120mm where clamping doesn't happen, dropped the seatstays, and altered the seat tube shape. They also added tire clearance up to 30mm, which translates to a 28mm Turbo Cotton on a Roval CLX 50 Disc wheel. This allows lower pressures for decreased rolling resistance, increased traction, and more comfort. Altogether, these additions still have the Tarmac riding like a true race-machine, but it also takes a bit of the sting out of road imperfections. You'll thank us on your next long ride.
But why disc brakes? The real question is "why not?"
They offer superior braking power and modulation, work exceptionally well in wet weather, and offer a very, very minor weight addition. All this means that you have more control and can go faster with more confidence.
We also know how important aerodynamic improvements are to making you faster. With this, the aero goal was to discover where "free aero" could be added while not taking anything away from the hallmarks of the Women's Tarmac design. During the six-month iterative process, three areas were discovered where they could do this—a new fork shape, dropped seatstays with aero tubes, and a D-shaped seatpost and seat tube. The result? A bike that's approximately 45 seconds faster over 40km compared to other lightweight bikes in the same category.
Next, Specialized included the lightest (440g/172.5mm) and most accurate power meter available, because no matter your skill level or experience on the bike, there's no better way to enhance your training and racing performance than by riding with a power meter. Lucky for you, Specialized combined their incredibly light and stiff carbon fiber S-Works road cranks with dual-sided power measurement.
This S-Works Tarmac comes ready to race with Shimano's new Dura-Ace 9170 Di2 groupset with disc brakes, light and aero Roval CLX 50 Disc wheels with 26mm Turbo Cotton tires, and a host of women-specific pieces at every touch point on the bike, like a superlative Oura Pro saddle.
