Are those the Pro 37 wheels on your wife's bike? I'm debating whether I should buy the Pro 37 or the Pro 51. I'm wondering if the 3 oz. less weight of the Pro 37 would be offset by the increased aerodynamics of the Pro 51. After further investigation, I see that the Pro 51 is considerably wider than the Pro 37. Do you know how wide of a tire can be installed on either? I have 28mm tires on OEM Bontrager Paradigm SL aluminum wheels on the Emonda.
I can't get either up here locally until February, and I'll be in Florida then. I might have to look down there if you get yours sooner.

I like the 37 depth, but having the better aero dynamics of the deeper wheels is what I wanted, and also wanted a slightly narrower internal width so the profile of the 28's would be a little less square compared to running them on the Pro 3v's. Those things are so damn wide at 25mm internal. The Pro 51 is only 2mm wider than the Pro 37, so not a huge different. 23 versus 21. You can pretty much install most anything on these, but limited by your frame. A guy at the LBS but a 40 on the Pro 37 and it worked, but was really right on the rear triangle.

I have a set of Pro 3V wheels as stock on my Domane as well as a set of RSL 51 wheels and the 51s aren't noticeably faster. So my recommendation is to get whichever of the Pro 37 or Pro 51 you can get sooner. Though the 51mm rims look cooler.
