If you want to go fast, like go fast everywhere, this is the bike. This is the bike that's made for everything from Grand Tours to your local fondo, and with a ground-up redesign, a heavy dose of aero wizardry, and of course, disc brakes, our "most complete race bike" is, well, even more complete.
Specialized added 200 more pieces to this carbon layup for a total of 500. Why? For you. The added complexity found here has given more opportunities to shave grams and tune the ride. Specialized examined literally every ply of carbon on every single frame size to ensure that all of their performance targets came through on the finished product. The process is absurdly detailed, because what works on a 49cm doesn't work on a 61cm. So, 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 aero development of the Tarmac took place over a six-month iterative process; but the knowledge of over six years, the data of countless aero projects, real world testing, and computation fluid dynamics were all pulled for the Tarmac’s development. In the end, three areas were discovered where Specialized could add aero for free—a new fork shape, dropped seat-stays with aero tubes, and a D-shaped seat-post and seat tube. The result? A bike that’s approximately 45 seconds faster over 40 kilometers compared to other lightweight bikes in the same weight category.
Options—we want you to have them. That's why Specialized made the Tarmac in a rim brake and a disc version. No matter your preference, we have you covered. And better yet, the two versions are evenly matched on aero performance, speed, and handling, so your choice is really left to what you like and not what you're willing to sacrifice.
