I felt I should do these rims a favor seeing how no one has reviewed them in some time.
I have not had any issues with these rims or wheelset. I would recommend making sure you go through every so often to check your spoke tension. For reference I weigh 180 and I have cased these onto rocks and not one single dent (I honestly cannot believe it). And they aren't even out of true.
I would absolutely recommend these to anyone looking for a diesel rim that can stand up to a lot of abuse and I would not hesitate building another wheelset with these rims.

Strengths: Stiff, Reasonable weight, never need truing, wide enough to give you a good tire profile, no burping, sets up tubeless nicely with UST,and non UST tires.
Weaknesses: Screw in eyelets loosened up a lot when new, but I think this was a setup problem as I doubt the builder used loctite on them. I have had problems with he valve stem on my rear rim leaking air from time to time (I have tried replacing the valve stem, loosening it tightening it, replacing just the o rings, using some stans etc, and I still get a tiny bit of air leak around the base from time to time)
These are a great all mountain rim for a really heavy rider 245lbs. I bought these as a set of prebuilt wheels). The first month I owned them I was constantly having to tighten the eyelets as they were backing out. I got tired of them loosening during a ride so I backed them all out enough to put a drop of loctite on the threads for each eyelet (this is what the instructions say to do when building the wheel, I am guessing whoever built the wheel did not do this). Tightened them back down and trued the rim. I have not had any issues with them since, and every time I put them in my truing stand they are straight as an arrow. They are a perfect width for a 2.35 - 2.5 profile tire.
Strengths: Lighter???? Everyone knows the name... so you get compliments.
Weaknesses: Too light duty, not enough strength in them...
These came stock on my bike. They were neat initially... but soon wore off. I like the tubeless feature, but it is useless if you are running tubes. The nipples need to be constantly checked. On a positive note these rims were stiff... they did not have any lateral flex. Further they took hard hits and did not buckle. But check your spokes. Note for wheel builder: these lace up with a lower spoke tension. The spokes will seem soft in comparision to other rims... DON'T over tension them... it will lead to premature eyelet failure.
Another problem I found with it was that they rims were too narrow for 2.5 or 2.7 tires. At lower pressures they would roll off the bead and burp. Jumping and hard corners you can definitely notice it. Recommended: run higher tire pressures- 40-50psi.
I would only recommend this rims if you ran it front only, and tubeless.
Strengths: Light Weight when run with tubeless tires and its bomb proof
Weaknesses: Maybe could be a little more down in the weight category, but the guy at Mavic would have done it if they could anyway
You cant go wrong with these rims and they are really a fit and forget kind of component. Have been blasting through and down rock gardens, drops, and hitting square bumps directly without any flex or signs of buckling. The weight was on the heavy side when i was using tubes but now since on tubeless, its a joy to pedal up occasionally. Would recommend these rims for a custom build wheelset and anyway its the same rims as the Deemax except for the hubs and spokes of course. But in the long run, you are saving more with building up your own rims.
Strengths: Very light, Very Strong, Tubless, Black!!
Weaknesses: Not as strong as others!
This is a fantastic rim. Strong and light. Being lighter doesn't just make it easier to lift your bike in to the van but reduces the rolling mass and thus making it a hell of a lot easier to acellerate out of the corners allowing you to reserve more energy and in turn making you faster. If you've been running ex729s or AtomLabs then you'll certainly notice the benefits of lighter wheels. Most cross country riders could easily get away with these rims. I've had no problem with these rims yet. I've only buckled one but that was my fault from riding too hard with too little pressure in the tyre. Apart from that combined with some sapim CX-Rays and a good wheel build these rims will set you appart from the competion.

Strengths: Awsome strength to weight. Wide cross section for tyre stability. Good tubeless system that just works. Welded joint.
Weaknesses: Black anodising is not as bulletproof as Mavic's CD finish.
I bought these as part of my "masterplan" to build a really tough all mountian bike that wasn't too heavy but handled really well. (No money left to eat though). Going from the stock Mavic 317 rims to these added a bit of weight but transformed the ride, not to mention the extra confidence I got to go off much bigger stuff. I run normal tyres without tubes. If you look around you can find cheap liquid latex to seal them. (Stan's "No tubes" costs stupid money where I live). It's cheap to maintain and ultra-relliable. I'm riding rock gardens, drops and urban. After ripping 2 holes though a tyre from a bad sideways landing, I expected the wheel to be Taco'd. I've never had to true them. I'm impressed. Some credit also has to go to the brilliant Hope Bulb hubs. These rims are great. I can see why that Greg bloke has them on that Honda thing!
I ride a cross country frame and definitely don't need these rims. I chose them just because they look cool and they're good and wide for 2.4 inch WTBs. I ride stairs and stuff but 517s held up just fine. The biggest difference with these rims for me is that they're more stable, being wider and stiffer than my cross country rims. I also like that they are so much heavier for the added stability at speed. 5 flaming chilis.

Weaknesses: none found
these things are very strong. they are still true after the first 100 mile truing 8 months ago.i dont do much downhill. but i do ride alot of very abusive trails and wanted tubless with the advantage of a wider rim and stronger than the xc versions around. they have held up fine for me and i am6'8" (245lbs.) i have done drops,rollins,rock gardens, and basically every thing you can do to abuse these wheels and the are very stiff.dont take for granted what the guy below me says. i dont know about downhill but they have held up to my oversized ass putten them through a years worth of abuse.and the hope bulb hubs are the bomb as well. the auto enguagement on the rear is almost the same quality you would get out of the kings for half the price.and i dont know how the other guy paid 700 for his with ringle hubs? at the same place i got mine for 500 bones and i got better hubs.

This rim sucks. I bought 4 of them to get me through the DH race season (1 for the front and 3 for the rear) I just got back from the first DH race at angelfire and I'm out of rims. I love tubeless but these rims belong on a beach cruiser. Lucky for me I had my single pair of trail pimps from last season with me or these 823's would have cost me the whole weekend. I'm going to stans my pimps and call it a day. These rims are another case of the words freeride and extreme being used to market tacos
