Black in color
carbon fairing feels flimsy and plasticky.
spoke holes are squarish and come down the side of the faring, similar to bontrager aura.

they still use the dtswiss 240 hubs. This was the announcement at the giant canada yearly event, so the giant rep in your area should confirm this.
see if you can see it.
scroll down to the advanced propel models. See the spoke holes into the wheel they are squarish. They also are angled.
but if you see the sl3 model, that spoke hole is directly in the middle and drilled to the size of the spoke.
