Regardless of the chunky offroad tires, a high-performance gravel bike needs are the same as the road - efficient pedaling and the ability to maintain speed in the flats and corners. This means you get the incredible power transfer you'd expect from a Cervelo road bike and predictable handling that stays stable in the corners. Aerodynamics, yup, you'll see that here too. While it may seem bizarre that a bike with 40c tires would consider aerodynamics, it's still one of the biggest things holding the rider back. Aerodynamic shapes are used when possible without affecting the bike's stability in chunky terrain.
