Product Information

Specialized Tarmac Pro SL6 Men's Road Bike 2018

Introducing the 2018 Specialized Tarmac Pro men's road bike built with the brand-new Shimano Ultegra 8150 Di2 groupset that provides smooth and reliable electronic shifitng. The Tarmac Pro has been built to provide true versatility to your ride with the ability to fit up to a 30mm tyre whilst lowering the frame weight to 950grams with the brand-new Fact 10r carbon fibre. Rider-First Engineered™ technology means the Tarmac is kept stiff yet compliant to allow you to ride on rougher ground whilst the new fork shape, dropped seat stays with aero tubes, and a d-shaped seatpost and seat tube provide incredible aerodynamics. To finish the bike off the Tarmac is kitted out with Roval CL 50 wheelset that provides the perfect wheel for long training days in the saddle. 

Full Specification



To get the weight around 950 grams, Specialized utilized advanced aerospace composite optimization software to revolutionize the construction and layup of our new FACT 10r carbon. It's the most advanced material and schedule they've ever made—the shape, schedule, and material optimization sheds nearly 200 grams. That's right, a 20% reduction in frame weight—the perfect recipe for your next hill climb PR.

Wheels & Groupset

The Tarmac Pro comes spec'd with Shimano's new Ultegra 8150 Di2 groupset with direct mount brakes and the affordable, yet impressively aerodynamic, Roval CL 50 wheelset with 26mm S-Works Turbo tyres.


A seatpost, designed by Specialized, that builds compliance into the upper 120mm where clamping doesn't happen features seat stays that are dropped and an altered seat tube shape. 

Tyre Clearance 

The new Tarmac can now fit up to 30mm tyres providing true versatility on your rides.
