For the construction, we utilized advanced aerospace composite optimization software to revolutionize the development and layup of our new FACT 12r carbon. It's the most advanced material, and schedule, we've ever made, and this allowed us to shed nearly 200 grams. That's right, a 20% reduction in frame weight—the perfect recipe for your next hill climb PR.
We also took significant steps to improve our Rider-First Engineered™ technology to ensure that the new Tarmac is stiff and compliant in precisely the right places, all while shedding some serious weight. From different layup schedules and materials to visibly different forks, we scrutinized every single aspect of the new Tarmac to ensure you're getting the perfect ride. 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, which delivers instantaneous response and optimal power transfer.
And while stiffness aids in the aforementioned, we've also designed a seatpost that builds compliance into the upper 120mm where clamping doesn't happen for optimal ride quality, dropped the seatstays, and altered the seat tube shape. We 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, however, that aerodynamic improvements are the most important thing we can do to make you faster. Our Bora-Hansgrohe and 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, 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.
This S-Works Tarmac comes with the best component spec around, with the all-new SRAM RED eTAP AXS groupset, hydraulic disc brakes, Roval CLX 50 Disc wheels dressed with 700x26mm Turbo Cotton tires, and even an integrated power meter in the RED AXS crankset.
