Mavic Rims

The 819 wasn't meant for abuse so i'm not suprised you were far from happy with it
No problem with 823's so far.
EX 500.
I ran 5.1s for a couple seasons,and liked them pretty well. They were actually easier to ghetto tubeless than the Stan's Flows I'm on now. A little heavier and a little narrower, but really nice rims. I'd buy them again without hesitation, just felt like trying something else. The Flows are really good too, light, wide, and are holding up really well.
I've never run 819s, so I don't have much to compare by, but my 5.1s made it through ~2.5 seasons of riding a couple times a week, everything from AM/ Trail to lift served DH at Platty and the like. I beat the piss out of them, though I do only weigh ~155#.
That's a pretty common novice mistake: forgetting to retension spokes after the first few rides.
Typical A-hole statement from kidwoo. I wouldn't expect anything less...That's a pretty common novice mistake: forgetting to retension spokes after the first few rides.
Yeah. This has been going back and forth for 5+ years...
go ex721 if you dont care about going tubeless
No, I think the 721 is the old 521, and the 823 is the old D321.
The D321 wasn't tubeless, it's more like the 729.
321=729 gray style and current black style the same rim
823 tubeless 2 versions the 1st one was lighter and dented and crack the second version is great they just have to be built up correctly.
721 and 521 different rims i think.

No problems with either the 721 (Dh bike) or the 5.1 ('everything else' bike)with stans set up. The 721 will 'require' a double layer of velox to build up the rim bed and get the tires to seat easier. The DTs set up tubeless very easy (single ply maxxis seat with hand pump every time).
The ex721 is 580g, the DT 5.1 is 500g. Your 819s are about 560g if you include the required nipple inserts. The only other possibility for a true UST rim from mavic is the 823 which is overkill for all but full on DH at 720g.
The ex721 is the old d521.
The new en521 is a completely different, lower end rim.

That's because you're too dense to recognize light ribbing apparently. Not my fault really.
Jokels: Sounds like the 721 ghetto tubeless is right up your alley. I didn't realize the weights were that close. And you KNOW how durable those things are.
EDIT: Just BE SURE TO TIGHTEN YOUR SPOKES.

the en521 is actually their higher end Am/enduro rim. pretty strong. been running them on my 4x/ds bike for a while.
Sorry, but it the en521 is not a high end Mavic product (uses 6061 rather than the more stiffer and more durable Maxtal).
The first number in their 'naming' designates the product 'level'. Odd numbers are non UST, UST rims are even mumbers. At this point, all UST rims are '7' construction and tubeless thus they are numbered '8'.
Thus, the five signifies a mid level rim, and since all of the other rims being discussed are either 7 or 8, the en521 is indeed a lower level rim.

What weight will stans and double layer rim tape add to the 721?
Not much weight benefit over the 823 left then, i think.
Check sicklines, they did a side by side comparison. I dont remember the weights, but the 721s ended up a little bit lighter.
There are downsides to the 823 (like any product) as well though. The sidewalls are VERY stout and seem to like to cut tires rather than deform (exact opposite of the DT 6.1s) so taking advantage of the lighter Maxxis UST tires seems to cause problems.
YES
Not Mavics fault... If you feel the bead on a UST Minion, you'll realize why they tear. Run 3C's or any standard tire besides the UST Maxxis models.YES
My 819 has been holding up. I used it a few times as a Downieville wheel, now just on XC bike.The 819 wasn't meant for abuse so i'm not suprised you were far from happy with it
I made a special effort to locktite the eyelets, but I have seen others come loose.
Absolutely true, my point was more this:
Proponents of the 823 often claim further weight savings by running maxxis UST tires (100g or so lighter than non-UST versions) with no sealant....
Unfortunatly all that gives you is an unreliable set-up.
Going to 3Cs and stans sealant (what I run on the 721s) adds ~150g per wheel compared to the 'ideal' of UST w/o sealant.
I ran a Conti Der Kaiser at the tail end of this season. (FYI, the tire I had weighed a touch over 1300. It performed well in my conditions too.)
I'll continue to run my 823s any way, but this tire is a good option for gram counters...
All you gotta know is the EX 823 are the toughtest the company makes. Having the UST rim has no holes drilled thru the outer rim wall to weaken the structure. No one can argue the ghetto eyelet nipple setup is a bitch, but mine have loctite and are fine. Its not the lightest rim, but as close to bombproof possible in my mind.
If you run a UST tire, it is great... just make sure to put a 1/2 dose of stanz in there because u'll constantly get lil punctures. Hell stanz even repaired a cut sidewall at the bead from a flatspot impact... and it sealed it for good.

"Mavic EN521 - 28 mm wide, SUP welded, eyeleted and made from the finest 6106 alloy, EN521 Disc is a disc specific rim, especialy designed for enduro riding."
Seems like Mavic's answer too DT's D5.1 in other words, single run rims for WC wins!
(The stacks of D5.1 at WC's are laughable and if you ask politely they'll give you a set for free.)
Anyone tried EN521 for DH yet?
Barel's Mondraker Maribor 2009[/QUOTE:
my thoughts exactly. it is a pretty good rim actually. as far as in their AM series it is the upper end. gotta be plenty strong to even last one run at a WC. i wont touch a dt rim here in santa barbara and the 521 holds up fine.
I have built up one wheelset on EN521's for AM use. My friend has been very happy with them, they've held up very well with very few flat spots and minimal truing/tensioning.
Would I consider them a "one run race rim"? They'd hold up way better than a 5.1, sure. But they might flat more since its a stiffer alloy and doesn't dent so much.
I use an en521 on the front with a ex721 in the back, it is a great combo. That being said I dont think you would have much trouble using a 521 out back for burly trail riding with a good build.
NoTubes Flow with yellow tape. It's a tubeless rim that is wider and stronger than the 819 but not much heavier. I have 4 and love'em.
Hope this helps. Found this a long time ago from one of these boards.
I think this has been answered before, but what rims are on Mavics pre-built wheels, like DeeMax, Ultimates, Crossmax SX, etc. ?
Edit (using the process of elimination and the above)
DeeMax = EX 823
Crossmax SX = XM 819
Ultimates?
Crossmax ST? (nice lil all mtn set imho)
