Yeah, according to BikeRadar, they're 1286g front and 1816g back, for a total of 3102g (~6.8lbs). I never weighed them myself and my wheels on my old bike were equally heavy, so anything lighter will probably feel awesome.

The biggest climbs I do during my usual training rides are maybe 6-7% in the steepest pitches, but I think since I'm used to climbing with my current wheels (the SSRs), even a "heavy" aero wheelset (3-4lbs) will make a difference.

And I do agree about the aesthetic appeal of aero wheels.
