2020 Specialized Tarmac SL6 Sport Disc

When Specialized developed the Tarmac Disc, they didn’t just want it to be
fast. They wanted it to be fast everywhere. Long climbs, windy flats, Grand
Tour stages, local fondos—Specialized built a race bike to be the most
complete out there.

How did Specialized build the 2020 Specialized Tarmac SL6 Sport Disc to be the most complete race bike out there? They started with their Rider-First Engineered™ frame with a perfectly-tuned ride quality for every size, added in some serious aero tech that makes it 30 seconds faster over 40 kilometers than the Tarmac SL5, and then made it 20% lighter. Nothing is lighter, faster, and better handling. This Tarmac comes with a reliable spec that includes Shimano 105 mechanical shifting and quick-stopping hydraulic disc brakes, durable DT R470 Disc wheels, and Specialized's fan-favorite Power saddle.

  • For the construction of the Tarmac, Specialized utilized advanced aerospace composite optimization software to revolutionize the construction and layup of their new FACT 9r carbon.
  • 500 pieces creating 7 different sizes with the same tuned ride–that’s Rider-First Engineered™. Specialized examine every ply of carbon on every frame size to ensure that all of their performance targets come through. To make sure you get the perfect ride, every frame gets a unique layup schedule with different ply arrangements, orientations, quantities of material in specific areas, and sometimes, even exclusive thicknesses and types of carbon itself.
  • Aerodynamics is the most important thing Specialized can do to make you faster, but with the Tarmac, they added aero features without any cost to weight. Through development, three areas were discovered where we could add aero for free—a new fork shape, dropped seatstays with aero tubes, and a D-shaped seatpost and seat tube. The result? A Tarmac that’s approximately 45 seconds faster over 40 kilometers.
  • The updated the geometry is based on countless Retül data points and professional rider input. This enabled Specialized to develop a Performance Road Geometry that perfects the combination of a responsive front-end and short wheelbase, which delivers instantaneous response and optimal power transfer.
