If I end up wanting to like do a duathlon or something, maybe I could then get another set of wheels that are more aero, but for someone with my crosswinds problem what is the largest rim you would advise in that situation?
But just for now to do well in group rides where I'm drafting 100% of the time and there's almost always climbs or at least rollers of some sort would light, like just under 1200g carbon clincher 24mm rims be a good idea? I was considering iteration 3 of American Classic Mag wheels, but I hear they won't be out til Sept and I really want something now. I was told tons of people here get their wheels super cheap from alieexpress from China and that it is safe. The mag wheels will be $1600. Wheels seem to be around $600 on alieexpress. At that price I could get several sets for all sorts of situations. At that price, why not get some tubulars eventually too for wheels that are like 980g. I was thinking to try the heavier clinchers first so that I would always have that as back ups, then maybe eventually get the tubulars if I think the wheels from China seem decent.
So would 24mm rims be aero at all? Would that be good for me to start with and if I did ever want something more aero, what could I get being so light and blowing in the wind? Would I put something different on the front and rear like with the enve smart wheel set since I think the wind really only shakes the front?
Thanks for any helpful advice! Maybe I am a Queenie Weight Weenie. I am a very light rider with a light bike.

Regarding depth of rim - what matters is how much weight you have over your front wheel. With your height and weight, I wouldn't want a deep front. I would recommend a HED Jet 4 front 6 rear or a November Rail 3 front 5 rear.
Don't you have a good bike shop or some fast person on the local ride to help you out? Lots of opinions on this board; as many bad as good!
aliexpress seems kind of random. I'd contact farsports (or light-bicycle or hongfu) directly.
The 50mm narrow v-shaped farsport rims I have do get blown around some. I'm 145 lbs. But besides body weight what matters here is how comfortable you are with a bike that's moving around a little. I find it annyoing when I first put the wheels on but after a half hour or so I forget about it. Unless I try to ride no hands in a cross wind. There's only been a couple times where I have really been blown around hard and the wind was so fierce that I'd have been blown around no matter what rims I had.
The more rounded shape rims are supposed to be less affected by cross winds.
Whatever wheels you get the improvement if any will be small. Learn how to position yourself in the pack for maximum advantage. Always be on the downwind side. If there is a hill coming up that you might get dropped on, move up. If you are near the front you can lose more time and still be in the pack. Make sure your position on the bike is as aero as is comfortable. (that will help with cross winds, the only aero that makes cross winds worse is wheels). If you're getting dropped on short hills then you need to do more short intervals. On hills 5 min and under the big guys can use some of their anaerobic capacity. While on long climbs it's power @ aerobic threshold / weight.

Light riders benefit the most from light equipment, and you are less likely to have any issues with stuff that is too light.
I'll second the mention of the XR200 rim. It's an old but reliable and inexpensive choice that weighs ~390g on average. Newer, wider and more rounded rims like the Stan's 340 and AC RD 2218 are in the same weight range and will be better for aero, but the 340's bead doesn't hold tires that well, and the AC 2218 has had longevity issues. Mated with hubs from BHS and CX-Rays you'd have a cheap and light set good for all around use.
But in the other hand if you wish to go with Chinese carbon, that might be fine too. Look for a rim that is rounded and wide if possible, even if it's shallow. It really does help for crosswinds to have the tire side and rim side look similar. Have an experienced builder stress relieve and check tension.
And carbon tubulars would be the ultimate for weight and aero... but dealing with tubulars is a whole new learning curve.
And don't neglect your tires and tubes either! The difference is pretty significant for resistance. I use latex tubes for everything. Some are light, but all of them have lower rolling resistance than butyl ones.
If I was as light as you and I wanted to go fast I'd ride the Conti Attack on the rear and the 20mm Supersonic on the front or Vittorias with the 320 tpi casing in 20 or 22mm.

If you've got any further info about issues with this rim put it in the 2218 thread. I haven't found anything but positive information other than it obviously won't be as stiff and durable as a 475g rim.
Get lightweight skewers from Ebay. Latex tubes and Diamante Pro Light or perhaps Michelin Pro 4 Comp/Light.

Note he says it was a NDS spoke. Since it is triplet laced I'd expect the NDS side to be most highly stressed (lateral forces) and the angle is extreme. Ideally a triplet rim should have an asymetric inner wall.
It also appears to have a small bead lip like the 340, so I suspect it will suffer from the same issue of some tires not hanging on very well.
16h front and 20h rear shouldn't give you any problems. My sister is around that weight and she rides older shamals 12f/16r spokes wheels which is a deeper rim. No wheel deflection and they are holding up well. She isn't very confident in crosswinds and close to busy roads because of the depth and shape of the rim.
If you struggle to find 16h hubs, get a 32h and skip every other hole. Good hubs (cfr Shimano DA, DTswiss, Bitex) are a well worth investment.
