2018 S-Works Tarmac Ultralight Frameset
The all-new Rider-First Engineered Tarmac.
The previous Tarmac had an exceptional palmarès—a win in every Grand Tour, plus two World Championships—so why a new Tarmac? Innovate or die. And for this 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, Specialized utilised advanced aerospace composite optimisation software to revolutionise the construction and layup of a new FACT 12r carbon. It's the most advanced material and schedule they've ever made—the shape, schedule, and material optimisation allowed us to shed nearly 200 grams. A 20% reduction in frame weight.
In the search to save every last gram, the S-Works Tarmac Ultralight also uses a newly developed paint finish that further reduces weight. It achieves a paint job that has the same weight as nine gummy bears, or 10 grams.
Specialized then further improved Rider-First Engineered technology to ensure that the new Tarmac is stiff and compliant in exactly the right places. With this revamp, they also updated the geometry—basing it on countless Retül data points and professional rider input. This enabled them 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 utilised for an optimal ride quality. They designed a seatpost that builds compliance into the upper 120mm where clamping doesn't happen, dropped the seatstays, and altered the seat tube shape. They also added tyre 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.
- Featuring 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 their highest quality carbon frame, offering the ideal blend of light overall weight and targeted stiffness.
- 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.

Free 6 Week Check
We offer a free 6 week check on all new bikes that we sell to guarantee that your bike is still running sweet. This check is basically the last step in a bike's quality control. We go over the bike and make sure it's safe, gears are tuned up, bolts are torqued up and that there are no potential issues.
Specialized has one of the bike industry's most generous, rider-oriented warranty policies to offer. They have expanded their coverage across their range of bikes and gear. Their frames and Roval wheels have a lifetime warranty and most warranties become transferrable to a subsequent owner, who will then be eligible for warranty 2 years from the original retail purchase date.
