59Kg, I’ve used combinations of 80mm front/rear and disc rear without being blown about on a windy outdoor velodrome, and I bop around the lanes on a set of 50/50’s without any trouble. I notice the wind a tiny bit more on my first ride on the 50’s after a winter on box sections, but never really had an issue or felt myself being blown around. it’s definitely more about the shape of the wheel.
imo if this is your climbing bike, just get a really nice light set of 20mm wheels if you don’t plan on riding fast on them i.e steep climbs.
if you plan on riding them on everything then get a decent shaped 40-45mm. they’ll be light enough to climb on and quick enough on the flats. just make sure to get a good shape.
also lol at thinking 60kg isn’t light, you’re just very petite.
