Carbon mountain rims are quickly gaining in popularity.
Edge Composites has been producing their carbon mountain rims for the last four years and they claim that their wide and tall All-Mountain rim is not only light, but of even greater importance, much much stiffer and stronger than its aluminum counterparts. On top of rims, Edge Composites also design and manufacture their impressive carbon Mountain Bar and carbon seat post.
Inside you will find all the specs and a great video.

One thing i'd be worried about is hitting the rims. I've got dents in my wheels which have dented the walls in, so what would happen if i did that to a carbon rim? Is that 900 quid down the drain? 721s cost about 45 quid, so its not TOO bad if you break them... i'd be more worried with these rims.
Though as you write here, I am also having concerns about their resistance to type of hits causing alu rims to dent.
The price is totaly different discussion, but well if their strength is comparable to EX721s, and they are stiffer (have to be as they are from CF) then 160g less of rotating mass might be worth it. (obviously for those who want to buy them: Im not one of them until I get a 6 figure GBP salary)
CEO: "Did you just say our nearest competitors msrp at $2300? Hmm i guess our customers won't notice another ten percent."
Take fox for example. A 36 rc2 was 1200, what will kashima coat cost extra now? In the meantime rock shox introduces a "new" Argyle with aluminum uppers and suggests retail at 700, because surely no one will notice its basically a solo air pike with slightly different cartridge dampers. Whatever the market will bear...
Deemax Ultimate, well 4 spokes more means only that is easier to true it, as the distance between spokes is only slightly smaller.
Regarding raise in price R-trailking-S: since when in any economy, market logics increase of variety of products makes them more expensive? Further, it is totaly illogical to me to believe that a new technology coming in is going to higher the prices of older one. It just works other way around - always. Thanks to development in new materials, older ones get cheaper.
Regarding Argyle: IMAO releasing it from the start with steel uppers was a stupid move from RS. It was expensive enough anyways so why not put lighter ALU legs...
Regarding Fox: it has always been expensive stuff for deep wallets. Companies thrive on this stupid lust for having the same thing that racers have. We eat our own sh*. Plus nobody forces anybody to buy anything. You don't like to pay for Kashima coating buy something older second hand.
As for a $900 rim that isn’t even tubeless ready – I would say back to the drawing board Edge, and look at what riders are really looking for.
SCottlanddownhill: regarding Edge rims I agree, it's stupid for them to say you can use conversion kit. Conversion kit gives you only one thing: puncture resistance for 1-ply tyres. It weighs more than a regular tube, and for 2ply tyres it makes absolutely no sense. Easton done their homework a bit better (though they still dont understand that 21mm inner width rim is an XC rim, not strong enough for i.e Alpine AM)
at least i understand AM as going up and then rocking it down to the bottom, as hard as the bike type lets you do it. If you want to go up 3000ft mountain and then ride carefuly so you dont destroy your wheels or get a puncture, take XC bike to save yourself some pain on the climb...
To the point: FOX Racing Shox actualy improves their products every year, and when you pay more money for it you actualy get more satisfaction. Not sure about RS but in most cases you get more with the price too. With Marzocchi you just get worse and worse product every year since 2006. even if those 2010 are getting good again, the price tag makes the buyer deserve a place on the forementioned list too.
66 models from 2005 and 2006 were truly the best long travel single crown forks ever. If I compare it now with this Totem crap it just makes me laugh... we'll see if Fox 36 180 will step up to the game...
As for prices going up - so did the manufacturing costs because the gear progresses.
And looking at the msrp of bikes (completes) - the economy was going up so the prices were going up, this season a lot of them dropped. Its normal. Now they are pretty much on par with 5000-6000$ for a top of the line dh bike from 5-7years ago.
But from what I know, rock gardens, sticks typical real world MTB beats the snot out of rims, let alone gouges and scratches them. Correct me if I'm wrong, but from what I know about carbon composite from racing RC cars, if its scratched, its trashed.
Perhaps they'll sponsor me????????/
