interesting read. With 40mm tires, only 1.8 watts are gained with aero wheels at 30 km/h. I am wheel shopping but this makes me rethink the need for deep carbon wheels for sure.

And if you’re on gravel gravel, you’re likely going to be on wider than 40mm tires making even less of a difference.
The cost is often not different between shallow and deep so I’d so go with what you think makes your bike look best.
So long as they are 25mm or wider internal, you’re not likely to notice a difference when riding.
It’s not all that different than road. I think road wheels/tires are around 3-6w for mid depth at 30kph. Paired with gravel tires, that’s reduced to 2-3w because of the airflow disruption from the tread. But it is still a marginal gain. And there has always been a lot of marginal gains that are more cost effective than wheels tho.
Not unexpected if you look at the mismatched tire width to outer rim with. At only 36.5mm outer width your “average” 42c gravel tire is well outside the ideal aero ratio.
If you’re really looking for maximum aero gains from wheels, you’re looking at least for a 40mm outer width à la 303 XPLR (which has its own shortcomings).
Yeah, do your shopping based on your needs not based on community hype trends
Yeah, but have you considered this…they look cool AF
