Mavic xm819

With this option stans & mavic EN821 same price:

Moonglu

Went to moonglu for mine – was recommended to get mavic over stans (and avoid wtb freq)

Dt swiss 350 hubs and mavic en821s appear to be just over 2kg on my dodgy scales – which normally add 10%

Hopes will be lighter again but won’t last as long

I’ll second the suggestion for Stans rims. I’ve used Mavic UST and Bontrager ‘Tubeless Ready’. My Stans Flow Ex (on Hope Pro 2’s) are the easiest rims to get a seal I’ve had.

Even Maxxis Highroller’s pop nicely into the rim. Have always struggled with that tyre in the past.

Stans rims seal better with non-tubeless tyres than UST rims and at least as well with tubeless ready and UST tyres as UST rims. So where is the folly?

I’ve not used Stans rims so can’t comment. My observation for other rims I’ve used:

Bonty TR tyres on Bonty TR rims: tyres go on really nicely (just put one on tonight). Soap and track pump, easy. But you have to have sealant (I always use sealant on all tubeless) and I find the tyre walls on Bonty TR tyres just too thin. I have about 4 or 5 bonty tyres that have lots of life in them but can’t be run tubeless due to unrepairable sidewall tears or kinked beads. Getting Mavic Minions & Conti RQs to seat on bounty rims is tough. Lots of sweat, swearing & soap.

I’ve 2 sets of UST mavic rims: 819 & 823. UST tyres go on beautifully. Such a good fit you could run them sealant free. Rims are bombproof and the weights confirm that. 819s are just too narrow though. I’ve burped RQ USTs off on 3 occasions. I’d love to build a set of EN821s on Hope bulbs for pedalling in the Alps this summer but think I’m going to have to put up with the 823s.

I only use TR & UST tyres for tubeless.

ex823 all the way. I use UST and LUST high rollers on these and they seal without any effort. You don’t even need sealant to run them. The only downside is the weight but in the end they are a bombproof set of wheels.

Got a brandnew Shimano xt755 full UST front wheel for sale, bought two sets for my 11 514 & only just sold up & gone 650b, it’s 15mm & spanking new if it’s of interest, theyre uber light & strong no faffing with rim tape either.

Cheers

Another happy 819 user here. They’re a bit awkward to build as they’re sealed inside (obviously) but they’re easy to live with, no strips to faff with, just whack tyre on, pump, Stand back and admire your handiwork. I think TBH Stans prob have the edge nowadays though, and I’d be looking at those next time (if my 819s ever wear out that is, as breaking them seems unlikely!)

Totally agree Northwind.

If the 819 was a bit wider it would be teh awsumz, but its not, so it isn’t.

in late night musings I worry about Stans rims being non eyelet, but I’m no great destroyer of rims so I doubt it’ll be a massive real world issue, in the same way that people go on about the weight of 819s, in truth my tubeless MK 2.4 plus 819 plus stock Atomlab 20mm hub is STILL lighter than my GF’s tubed NN running on stock Giant AX2 rims with a boggo SLX 9mm hub

FWIW I cracked a Flow at the valve hole. But my 721s cracked to **** at the eyelets 😆 I’m no expert but I figure pressing in the eyelets has got to stress the rim a little. And obviously means less metal to “spend” elsewhere. I think with a good non-eyelet rim there’s less difference than there used to be but probably makes more difference if you want the wheel to last 10 years- there’s different sorts of strong.

Scott, oh aye, I know but the 819 is 450g with the eyelets, 823 are well into 700g territory, Whereas Flows are 490g and arch ( a better 819 comparison) are 400g

Mavic rims a bloody ace, don’t get me wrong, but the same width with considerably less weight is a no brainer really

Edit: re your flows! 😯 blimey!! D’you know why they collapsed?

@Scottchegg, what caused that? Unless the nipples pulled through the rim, it’s nowt to do with eyelets…

I take it back then, they were exactly the same as the X3.1 they released in 2001 when they launched UST. Sounds like they’ve recently updated.

You’re right, we’re not all fascinated with weight, but the vast majority of people who ask about wheels have weight as a very high motivator for change. Particularly when the XM819s come up narrow too, which is another regularly touted desired criteria. So yes, they’re strong. But are they stronger than actually comparable rims?

I’m still rocking the Shimano on my 2010 514, been a solid set of hoops, only had one rear hub replaced. If I were to replace them I’d probably give the maxlights a try.
