When it was time to design a new Tarmac, we were daunted as to how we were going to improve on the previous model. Already offering exceptional low weight, supreme stiffness, and that good ol' race snappiness, what were we to do? Easy. Turn traditional design on its head and develop the new S-Works Tarmac Ultralight. Without a doubt, it's the fastest race bike you’ve ever ridden.
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 made—the shape, schedule, and material optimization 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.
In our 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 our improved preparation process, it achieves a paint job that has the same weight as nine gummy bears, or 10 grams.
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 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, 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 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 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 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 you'll feel when you're attacking off the front of the peloton.
- Featuring our Rider-First Engineered™ design that ensures every frame size has the same legendary climbing responsiveness and descending prowess you'd expect from a Tarmac, the S-Works FACT 12r frameset is our highest quality carbon frame, offering the ideal blend of light overall weight and targeted stiffness. This Ultralight iteration also features our 10g paint finish that saves every possible gram.
- S-Works full FACT carbon fork with a tapered construction provides incredible front end stiffness and steering response for instantaneous accelerations and high-speed descents.
- With its high-modulus construction, the S-Works FACT carbon Tarmac seatpost provides impeccable power transfer, while still allowing for ample compliance for long days in the saddle.

After racing a Specialized S-Works Tarmac for a couple of seasons I was looking for a replacement bike for 2018. I started looking at other brands but then heard Specialized had a brand new Tarmac in progress! I had a chat with the Specialized tech guys and the performance figures sounded very impressive, increased stiffness, more aero and increased comfort.Wind tunnel testing results were very impressive, it was time to try a demo bike over my regular 100k route. Being very honest it was as good as it gets! Very responsive out the saddle and accelerated really well out of corners. This ride was part of my training program so with the included efforts it was going to test most of the bikes ability. Power stomps while seated were fun, if fun is the correct description! As soon as the power went down the bike came to life, same on the climbs with efforts.After riding this bike I ordered a 56cm Ultralight frame and started choosing my favourite equipment.Specialized Roval 50 carbon wheels. I used these last season and love them, reliable and fast.Zipp sprinter stem, once again an old favourite which is super stiff.Enve carbon bars as they fit my hands really well and very comfortable.Specialized S-Works Romin Evo carbon saddle - Light and fits me well.Lizard Skin 2.5 bar tape.Specialized S-Works tyres 24mm, I've had great success with these and zero flats.Elite carbon bottle cages, holds the bottle well even on very rough roads and cobbles.Look carbon pedals, industry standard!Quarq carbpower crank. Super accurate reading and sleek carbon cranks.
