When they developed the Specialized 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 fondosthey built a race bike to be the most complete out there.Key Features SL6 carbon frame with race geometry Carbon disc fork Shimano 105 2x11 speed drivetrain for crisp shifting Shimano hydraulic disc brakes for all weather stopping power Sizes 44, 49, 52, 54, 56, 58, 61cm Colour CarbonSmoke The Specialized Tarmac SL6 Sport 2021 is available with 0% APR financeSpecialized Tarmac reviewHowd they do it They started with the 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 our fan favorite Power saddle. For the construction of the Tarmac, we utilized advanced aerospace composite optimization software to revolutionize the construction and layup of our new FACT 8r carbon. 500 pieces creating 7 different sizes with the same tuned ridethats Rider First Engineered. We examine every ply of carbon on every frame size to ensure that all of our 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 we can do to make you faster, but with the Tarmac, we added aero features without any cost to weight. Through development, areas were discovered where we could add aero for freea new fork shape and dropped seatstays with aero tubes. The result A Tarmac thats approximately 30 seconds faster over 40 kilometers. The updated the geometry is based 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, which delivers instantaneous response and optimal power transfer.
