At at 135lbs, my weight is probably less than most people in this forum but i'd like some opinion on aero wheels. I'm looking in to some aero (clincher) wheels for racing and some fast rides and I have a couple in mind like Enve 6.7 or Zipp 404. My problem is will this depth be problematic in the winds (usually around 5-15mph) considering my weight?
I don't think you will have any issues at wind speeds of under 15mph. Both of these wheel sets are rather deep, the enves at 60mm front and 70mm rear and the zipps at 58mm. The new rim shapes are supposed to be incredibly well mannered in cross winds.
The problem you may have is that when winds are around 15mph you are likely to have gusts around 20mph+. At 135lbs on a 60mm deep wheel this will probably cause some trouble.
Have you looked at the 3.4's and the 303s? They are still incredibly aero and at those depths they would be very well behaved in some hefty winds. The 303's would probably be the best option for you at 45mm deep. I ride enve 45's and even with the old style v shape they behave well in harsh winds, even over 25mph, although I am a considerable bit heavier at 165.
