If I look at the images of the Specialized Diverge Elite E5 I see on the underside of the seat stay 2 black pieces that look like rack mounts.
However, I've only seen them on the upper side of the seat stay. Are they pannier rack mounts or something else? If they are rack mount, how can I connect a rack to them? Is there a reason to add those to the bottom? Does that somehow improve something?
