[#4126334]

I am about to build new wheels but not sure whether to use a Flow rim with a Stans tubless kit (used em before) or a mavic/DT tubless rim and UST tyres. I presume that I will pay extra also a little more weight but is there any other advantages or dis-advantages.

Think Stans have all the advantages don't they? Weight, choice etc. Unless mavic have brought out some new UST rims just recently that I've not seen.

I use UST tyres on stans - I'm a heavier rider and they're just tried and tested for me - and reliability is the only reason I use tubeless in the first place. Obviously though you can run tubeless ready or normal tyres on Stans with the right tyre choice so that gives them still more versatility.
Not sure how non-UST tyres get on with an 819 - I'd imagine it would be a ballache but I've never tried it.

I have just started running my Mavic 819's with Nobby Nicks proper UST stylee with no sealant.
So far i'm really impressed.
Im running 30 psi and have had no air loss since they were fitted.
The only criticism so far is that the tires are quite hard to put on, i bought some racing ralphs to swap between but i doubt i will bother now.

rim? you choices will be the portly 819 or the silly heavy downhill version (823 - 650g pretty sure that doesn't include the fore nipples ~50g) dt don't do a rim do they? For a decent range and light weight you need to look at UST wheels, not rims.

Not sure either that DT do a UST rim its just a example. I have Stans crest & run Rocket Rons with the sealent but I am sick of em going down all the time yeh it may take a week but it still drives me insane. May be it would be better useing a UST tyre with Flows?

A UST tyre is very good at retaining air on a crest - stay up for months IME.
I like the robustness of UST tyres, but they are expensive. Pushing 50 quid for something like a rubber queen - OK if you're banging it on there for 2 years, but pricey if you like to chop and change.

I do like the Crest rim but wanted somthing this time a little more robust like the Flow for example with a UST tyre?

I've used Flow rims tubeless with non-tubeless tyres (mixed results), tubeless ready tyres (all worked well) and a UST tyre (worked as well as the tubeless ready but needs less sealant). In an ideal world I'd go for a reinforced casing (Protection/Armadillo/Snakeskin/etc) with a tubeless ready bead as that gets the toughness of UST (or more?) with less weight even with the extra sealant.

Thanks all I think that I will use a flow rim & UST tyre with a little sealant and hopefully pull some decent results. Better start saving my pennys ๐Ÿ˜‰

Have got roughly 9 years of experience running tubeless now, used all sorts of different combinations over the years, predominantly proper UST rims but all sorts of others as well.

IMO it's the tyres that make the biggest difference. If you use porous, non tubeless type tyres, then expect it to be a headache no matter what rim you use. If you use proper UST tyres with sealant (or at least Tubeless ready tyres with sealant), on pretty much any rim, then it's a very reliable setup. You can of course run UST rims with UST tyres without any sealant in, and they're pretty reliable like that... Until you get a thorn puncture! I always run a little sealant regardless these days.

UST rims lack choice, which has always been most people's biggest criticism of them. Of course, Mavic want you to buy their full wheelsets such as Crossmax SX or the like, which come with a decent width rim that's pretty light and UST ready. Sadly they don't offer any similar rims on their own, which has probably hurt Mavic more than its helped them (Mavic hubs aren't so great, and 24 alloy spokes isn't such a good idea either IMO), as the 819 whilst very stiff and strong is also narrow and heavy (510g inc. nipple beds) for an XC rim, and the 823 is just a beast at approx 720g inc nipple beds.

Oh, and a quick note about non UST tyres should you choose to run them, they're not all created equally. For instance, Maxxis Dual Ply's run very well in a tubeless setup, whereas many others don't.
