The rotor on the rear wheel almost disappears into the bike. There's a cassette on one end, a rotor on the other, it's like circular book ends. Front one stands out a little more.
I thought the DA rotors were ugly at first, the black fins seemed to make them stand out. But in a dark bike with black carbon rims, they look like they belong.
Flat mount looks like part of the frame.
I've always liked the aesthetic of modern race bikes, and disc brakes fit in pretty well.
