Specialized's S-Works Tarmac may be the optimal bike for winning a Grand Tour, but chances are, you're not going to be competing in Southern France this season. But when you need a bike that's ready to annihilate the competition on your training rides and local races, the S-Works Tarmac Sagan Superstar Frameset is hard to beat.

To get the weight around 800 grams, Specialized utilized advanced aerospace composite optimization software to revolutionize the construction and layup of their FACT 12r carbon. The material optimization allowed them to shed nearly 200 grams. That's right, a 20% reduction in frame weight—the perfect recipe for your next hill climb PR.

While stiffness aids in the aforementioned, compliance must also be utilized for an 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 SLX 24 rim. 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 just takes a bit of the sting out of those road imperfections.

Specialized knows that aerodynamics are the most important thing they can do to make you faster. Bora-Hansgrohe and Team Quick Step Floors Pro Tour riders, after all, are demanding aero improvements on every bike. With this, the aero goal was to discover where they could essentially "add aero for free," by not taking anything away from the hallmarks of the 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. A speed savings that you'll feel when you're attacking off the front of the peloton.

- Featuring Rider-First Engineered design that ensures every frame size has the same legendary climbing responsiveness and descending prowess you'd expect from a Tarmac, the S-Works FACT 12r frameset is their highest quality carbon frame, offering the ideal blend of light overall weight and targeted stiffness. This Ultralight iteration also features 10g paint finish that saves every possible gram.

- S-Works full FACT carbon fork with a tapered construction provides incredible front end stiffness and steering response for instantaneous accelerations and high-speed descents.

- With its high-modulus construction, the S-Works FACT carbon Tarmac seatpost provides impeccable power transfer, while still allowing for ample compliance for long days in the saddle.
