Wheelset depth for all-round wheelset?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Oh noes, what am I to do now?

I think both wheelsets weigh about the same. I like the carbon ones because the hub is ridiculously loud. I like the Ambrosios because they have the brand written on the rim on a big font and have silver hubs.

Yes, this is true. I was implying the difference is likely 1-2 watts at like 40-50 kph or whatever max speed you would attain, and less than 1 watt below that. Nobody is cycling faster than that, so it doesn't matter, ever, I would say.

Really all these aero things are a bit nonsense, unless in a professional time trial, where every watt counts, where you are going 50 km/h in the wind by yourself, and where 1 watt on tire + 1 watt on skinsuit + 1 watt on chainrings, etc. adds up in the end.

I blame Team Sky for this stupid "marginal gains" stuff.

Even in worldtour racing, some riders prefer to be on the lighter "non-aero" bikes, even on relatively flat stages. It is not unusual to see some riders be on aero bikes and others on the light bike in the same race within the same team. Which tells us: it really doesn't matter that much in your average non-TT race.

The only 3 "aero" things with significant impact in the range of 10 watts or more are:
- Rider position
- Wheelset
- Helmet

Everything else is meh...

- Mostly flat terrain, and would like it to be as aero as is practical.
- Probably will take weekend trips to mountains / hilly terrain
- Occasionally very windy, and don't want to have to leave the wheels at home for that. (I weigh 150 lbs if that matters at all)

What is the best depth to go for an all-round, do-it-all (semi-)aero wheelset? 35mm? 40mm? 50mm? 60mm? Something else?

I'm looking at some nice 60mm wheelsets, but it seems like those would be too deep for all-round usage?

Thank you!
45-55 is the most popular depth I see at road races, and I run a 55 for every day and 65 for race day. Either woudl be fine for an every day wheel, and you're not going to have wind issues in ordinary conditions. In the past 5 years, I swapped my front wheel to a 35mm wheel once, for a race that had steady 25 mph cross winds with 40 mph gusts. My deeper wheels would have been manageable in those conditions for a solo ride, but I worried about riding in the pack.

Crux of the matter - if the 60 mm wheels you're looking at suit your needs, they'll be fine.

Definitely agree, if its all at 55 or 60kph or above them it's really a moot point for almost everyone.
