I’m looking at upgrading the current wheelset on my 2012 Colnago EPS. I’m looking at Light Bike, and they have a 35mm and 45mm deep rim I can choose from. Here’s the issue: I’m light. I mean really, really LIGHT. I’ve read a lot of threads where guys say “Oh, yeah. I’m light (60-65kg), and I have no issues with a 50/55/60mm rim in crosswinds”. Sorry, but that’s not light. My race weight is ~52-53kg. At peak fitness, I’m at ~215-220 FTP (~4.0-4.1 watts/kg), so I can climb really well. The problem is, I get blown around in crosswinds.
So my question is for you sub-60 kg’ers. What is your experience with aero rims and crosswinds? Should I err on the side of caution and go with 35’s? go out on a limb and do 45s? 45 rear/35 front? I welcome your input.
