e11 is, um, yeah, um, you need to get that out of your mind. Any aero gains with those are lost as soon as the earth pitches up.
Roval is the Specialized house brand (they bought them a few years back), so you will get a very well built wheelset, and very durable, but there's a premium to be paid for them. You can absolutely get a lighter wheelset for less.Have you checked
Light Bicycle? You can spec a wheel in the same range, maybe $100-200 more with DT Swiss hubs and Sapim spokes that is lighter than both of those and get the aero advantage of a medium depth rim that is also lighter than both of those.
How about a wheelset based on this
rim starting at $651? I bet you can build it to be far in excess of those wheel sets (DT Swiss 240 or 180 with Sapim spokes?), and you'll ever regret your purchase.
