Specialized developed the Tarmac Disc to be fast everywhere, from long climbs to windy flats and Grand Tour stages to local fondos. They built a race bike to be the most complete out there. Specialized started with their 500-piece, Rider-First Engineered™ frame with a perfectly-tuned ride quality for every size, added in some serious aero tech that makes it 45 seconds faster than the Tarmac SL5, and then made it 20% lighter. Nothing is lighter, faster, and better handling.
For the construction of the Tarmac Disc, Specialized utilised advanced aerospace composite optimisation software to revolutionise the construction and layup of the new FACT 12r carbon. It's the most advanced material, and schedule, Specialized have ever made, and this shed nearly 200g - that's a 20% reduction in frame weight.
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 Specialized's 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 are the most important thing Specialized can do to make you faster, but with the Tarmac, aero features were added without any cost to weight. Through development, three areas were discovered where aero could be added for free - a new fork shape, dropped seatstays with aero tubes, and a D-shaped seatpost and seat tube. The result is a Tarmac that’s approximately 45 seconds faster over 40 kilometres.
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.
