The previous Tarmac had an exceptional palmarsa win in every grand tour plus two world championships so you might ask yourself "why a new tarmac?" well Specialized have never been one to rest on their laurels which is why we're constantly hunting for even the smallest of improvements. In other words we innovate or die. And for this exact reason the new S-Works Tarmac breaks all the traditions of race bike design to create the fastest bike for all conditions.
To get the weight below 800 grams we utilized advanced aerospace composite optimization software to revolutionize the construction and layup of our new FACT 12r carbon. It's the most advanced material and schedule we've ever madethe shape schedule and material optimization allowed us to shed nearly 200 grams. That's right a 20% reduction in frame weightthe perfect recipe for your next hill climb pr.
We 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 geometrybasing it on countless retl 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 utilized 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 tire 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. 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 thanks us on your next long ride.
And while this is all great we know that aerodynamics are the most important thing we can do to make you faster. Both our 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 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 thisa 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.
