Seven different sizes with the same tuned ride. The only way to do this is to obsess over every carbon ply and arrangement. It isn't the kind of glamorous work that lands you on the cover of magazines. Nope. It's scientists scrutinizing every thickness and shape, having heated arguments over stiffness targets and handling prowess like we have our own model UN, but you'd never notice that when you're riding a Tarmac. You'll just feel like you're riding the perfect bike.

We literally examine every ply of carbon on every single frame size we make to ensure that all of our performance targets come 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.

Below, you'll find just a few of these places where this dark magic is applied:

The aero development of the Tarmac took place over a six-month iterative process, but the knowledge of over six years, plus 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 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 bike that’s approximately 45 seconds faster over 40 kilometers compared to other lightweight bikes in the same weight category.
