Is there something I'm missing ? I don't see many if any people running Crest mk3's for gravel. The hoops are lighter than most gravel/road hoops and I rage them on my mtn bike(hardtail) so I know they will handle the abuse. I have a 2018 carbon diverge that will handle 40 ish tire and I weigh 170. Any reason I shouldn't use crests?

As most people run 700c wheels on gravel, I think it would be due to the Crests max psi rating. i.e. they are marketed as a mtb rim (lower pressure end), rather than a gravel rim like the Grail.

I'd check the numbers on the Crest, against what pressure you want to run those 40's at.

I have some 650b Crest wheels and I am personally not a fan, they are flexy and go out of true easily.  They are very light though at 1350g with AC hubs and CX-ray spokes.

I've been railing a set of Crest ZTR's on (in order) my 29er touring bike, my XC race bike, and now my gravel bike and I have loved them.  They've been plenty stiff and burly (I toured, fully loaded, across 200 miles of dirt on them without needing to true them when I got home). 

However, that was the Crest ZTR.  The MK3 is about 2mm wider, which is pretty wide for a gravel rim.  Most of the tires are designed for rims with an internal width of 19-21mm wide, which the ZTR's sit right at 21mm.  With that extra width, the tread squares off and you lose some cornering ability due to shoulder knobs pointing straight down instead of diagonally to the ground.

Second thing is, like owly said, the max pressures that you can run with a gravel tire on that rim are pretty low.  I run my Panaracer Gravel King SK 35mm's (which blimp out to 40mm on that wide rim) at a max of 45 PSI.  While this is still high enough to allow me to keep up w/ my roadie friends, it's not all that high.  Granted, race PSI for a lot of those tires is like 35ish PSI, but for every day riding, that's pretty low.

I've not had the best luck with Stan's wheels. Had a 3.30 freehub  with <1000 miles on it fail without warning on my mountain bike while climbing about 6% grade (and I'm not a powerful rider). I had a set of Crests on my Vaya and they provided a great feel at low pressure with wide tires (42mm Spec. Sawtooths and 40mm WTB Nanos). With the big tires, I never ran them over 50 psi, so that wasn't an issue. However, on my third visit in 6 months to my LBS to have them trued, the mechanic told me those rims are made from 'butter and tears'. Could definitely feel the flex when out of the saddle. I've heard newer Stan's hubs are beefier, so if you are <175 lbs., run wider tires at low pressures, don't beat up your gear and want a light weight wheelset on a budget, they might be an OK choice. I'm currently running American Classic Mountain Bike Race wheelset and much happier with these.
