Its simplewhen someone attacks on a climb, you want to respond quickly and with confident assurance. And when its you whos breaking away, you need to accelerate with snappy intensity and leave everyone in your dust. The Womens S-Works Tarmac SL6 with Shimano Dura-Ace Di2 is born to race to any strategy, and its at the absolute top of the womens race bike heap in terms of performance, quality, technology, and handling.

For the construction, we 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 weve ever madethe shape, schedule, and material optimization allowed us to shed nearly 200 grams. Thats right, a 20% reduction in frame weightthe perfect recipe for your next hill climb PR.

We started by further improving our Rider-First Engineered technology to ensure that the new Tarmac is stiff and compliant in exactly the right places, all while shedding some serious weight. 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. Thats why we designed a seatpost that builds compliance into the upper 120mm where clamping doesnt 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. Youll 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. Our Boels-Dolmans 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 thats 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.

The new Womens S-Works Tarmac comes ready to race with Shimanos new Dura-Ace 9150 Di2 groupset with direct mount brakes, and the lightweight, yet impressively aerodynamic, Roval CLX 50s with 26mm Turbo Cotton tires. Its also specd specifically for female riders, from the handlebar width, to the crankarm length, all the way down to the saddle.
