2020 Tarmac Disc Comp – Ultegra Di2
When we developed the Tarmac Disc, we didn't just want it to be fast. We wanted it to be fast everywhere. Long climbs, windy flats, Grand Tour stages, local fondos—we built a race bike to be the most complete out there. How’d we do it? We started with our 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 no-fuss spec that includes Shimano Ultegra Di2 electronic 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 9r carbon.
- 500 pieces creating 7 different sizes with the same tuned ride–that’s 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.
- The updated the geometry is based on countless Retül 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.
- 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, 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.
