To get the weight below 800 grams, Specialized utilised advanced aerospace composite optimisation software to revolutionise the construction and layup of our new FACT 12r carbon. It’s the most advanced material and schedule we’ve ever made—the shape, schedule, and material optimisation allowed us to shed nearly 200 grams. That’s right, a 20% reduction in frame weight.
Specialized then further improved our Rider-First Engineered™ technology to ensure that the new Tarmac is stiff and compliant in exactly the right places. With this revamp, we also updated the geometry—basing it on countless Retül data points and professional rider input. This enabled us to develop a performance road geometry that perfects the combination of a responsive front end and short wheelbase, delivering instantaneous response and optimal power transfer.
And while stiffness aids in the aforementioned, compliance must also be utilised for an optimal ride quality. That’s why we designed a seatpost that builds compliance into the upper 120mm where clamping doesn’t happen, dropped the seatstays, and altered the seat tube shape. We also added tyre clearance up to 30mm, which translates to a 28mm Turbo Cotton on a Roval CLX 50 wheel. This allows lower pressures for decreased rolling resistance, increased traction, and more comfort.
During the six-month iterative process, three areas were discovered where we 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.
- Featuring our 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 our highest quality carbon frame, offering the ideal blend of light overall weight and targeted stiffness.
- 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.
