When we developed the new S-Works Tarmac Disc frameset we didnt just want it to be fast. No we wanted it to be fast everywhere. Long climbs windy flats Grand Tour stages local fondos—we built a race bike to be the most complete out there. & now with disc brakes weve managed to make it well even more complete. For the construction we utilized advanced aerospace composite optimization software to revolutionize the construction & layup of our new FACT 12r carbon. Its the most advanced material & schedule weve ever made & this allowed us to shed nearly 200 grams. Thats right a 20% reduction in frame weight—the perfect recipe for your next hill climb PR. We also took major steps to improving our Rider-First Engineered™ technology to ensure that the new Tarmac is stiff & compliant in exactly the right places all while shedding some serious weight. From different layup schedules & materials to visibly different forks we scrutinized every single aspect of the new Tarmac to ensure youre getting the perfect ride. With this revamp we also updated the geometry basing it on countless Retul data points & professional rider input. This enabled us to develop a Performance Road Geometry that perfects the combination of a responsive front-end & short wheelbase which delivers instantaneous response & optimal power transfer. & while stiffness aids in the aforementioned compliance must also be utilized for an optimal ride quality. Thats why we designed a seatpost that builds compliance into the upper 120mm where clamping doesnt happen dropped the seatstays & 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 Disc wheel. This allows lower pressures for decreased rolling resistance increased traction & 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. Youll thank us on your next long ride. But why disc brakes? The real question is why not? They offer superior braking power & modulation work exceptionally well in wet weather & offer a very very minor weight addition. All this means that you have more control & can go faster with more confidence. We also know however that aerodynamic improvements are the most important thing we can do to make you faster. Our Bora-Hansgrohe & Quick-Step Floors Pro Tour riders after all are demanding aero improvements on every bike. With this the aero goal was to discover where we 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 we could do this—a new fork shape dropped seatstays with aero tubes & a D-shaped seatpost & seat tube. The result? A bike thats Approx. 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 & descending prowess youd expect from a Tarmac. The S-Works FACT 12r frame is our highest quality carbon frame offering the ideal blend of light overall weight & targeted stiffness. S-Works full FACT carbon fork with a tapered construction provides incredible front end stiffness & steering response for instantaneous accelerations & high-speed descents. A legendary Ceramic Speed bottom bracket ensures that youre saving every last precious watt.
