Isn't that first one a v not a u profile?

The light bike U is 35mm, lighter but a bit narrower I think.

You right - that is V. Corrected the OP

I guess i just want to understand more about widths and profiles.

Lets say I'm running 25mm in summer and 33mm (max) in winter - which rim width do I want?

Also, will a 38mm V shape be more susceptible to crosswinds than a 45mm u shape?

I thought no one was using V shapes anymore except Lightweight. Because U is better in almost every circumstance. I read an article about it. But I know almost nothing so take that with a pinch of salt.

Edit: found the article https://www.cyclingweekly.com/news/latest-news/u-shaped-deep-section-rims-198572
