When it was time to design a new Tarmac, Specialized were daunted as to how they were going to improve on the previous model. Already offering exceptional low weight, supreme stiffness, and that good ol race snappiness, what were they to do? Easy. Turn traditional design on its head and develop the new S-Works Tarmac. Without a doubt, its the fastest race bike you’ve ever ridden.
To get the weight below 800 grams, Specialized utilized advanced aerospace composite optimization software to revolutionize the construction and layup of our new FACT 12r carbon. Its the most advanced material and schedule they have ever made—the shape, schedule, and material optimization allowed Specialized to shed nearly 200 grams. Thats right, a 20% reduction in frame weight—the perfect recipe for your next hill climb PR.
In their search to save every last gram, the S-Works Tarmac Ultralight also uses a newly developed paint finish that further reduces weight. In combination with their improved preparation process, it achieves a paint job that has the same weight as nine gummy bears, or 10 grams.
Specialized then further improved their Rider-First Engineered™ technology to ensure that the new Tarmac is stiff and compliant in exactly the right places. With this revamp, Specialized also updated the geometry—basing it on countless Retül data points and professional rider input. This enabled Specialized 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 utilized for an optimal ride quality. Thats 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. Specialized also added tire clearance up to 30mm, which translates to a 28mm Turbo Cotton on a Roval CLX 32 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 just takes a bit of the sting out of those road imperfections. You’ll thank Specialized on your next long ride.
And while this is all great, Specialized know that aerodynamics are the most important thing they can do to make you faster. Both the 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 youll feel when youre attacking off the front of the peloton.
