DT and stans both claim to be tubeless compatible if you fit rim strips.
Mavic don't, but surely are in the same boat? I've run stans strips and UST tyres before.
UST is just a rim without holes in it?
Have I got that right? In which case, how are stans so expensive and light compared to other rims, I know they have a shalower rim, but then so do my en321's.

No it's got the "proper" profile for ust tyres.

Light stuff generally costs more! - or am I missing your point?
Possibly, just condidering a new wheelset as I've not really found anything secondhand that really takes my fancy.
Stans flow on pro 2's would be the benchmark, but I'm just a bit put off that a) theyr not actualy UST rims, so why am I paying so much more, and b) they're light, if i thought I could get away with it i'd keep my dt 4.2's, but I suspect they're only ever one case away from being mullered at jump gulley/sandy cutting.
I've not broken my 4.2's yet, but was wondering relatively how strong flows would be and whether they're a worthwhile upgrade.
I got these - see link - as a better alternative in my view ......
just fitted the tubeless option today, having run them with tubes for the past 2 months. Went on pretty well.
Rims have a deep - easy fit - groove for the tyre bead.....
Stans holds onto UST beads pretty well IME. Much, much better than regular bead.
Light, cheap, strong pick 2.
Flows will be infinitely tougher than 4.2s, whilst weighing less.
Stan's rims are very slightly larger diameter, and have the 'Bead Socket Technology' thing, which basically just means that tyres will inflate far more easily than on other non-UST rims and will stay on at lower pressures.
UST tyres actually 'lock' into the bead, so they're a tighter, and more fool proof approach, but it weighs more.
I'm not denying the "cheep/light/strong pick 2" mantra, I'm just struggling to see how stans can have somehow beaten mavic/DT at their own game and produced a rim thats lighter than their XC offerings and stronger than their 'all mountain' offerings?
more weight = more material = more strength Where have stans shed the weight that the big boys have been leaving behind for some reason all these years?
Remember the 90's? Take away material, make it lighter, it breaks.
and how come theres only 1 xc UST rim available? and at 500g ish an 819 aint exactly xc weight - and 32h only 🙁
As you can see from this link

Each rim has a hollow section. Stans stuff this space with crisp dollar bills which they are literally rolling in by charging so much for their products. The money is also starting to get in the way at the office.
Handily the properties of the American greenback just happen to have the right vibration absorbing properties to make the rim strong while keeping the weight low.
Hence the light/strong/cheap statement is fully satisfied. Does that answer your question ?
Don't buy them then?
😯 🙄
From what I can see stans use better materials, which cost more, nothing complicated going on.
I am surprised that the other manufacturers haven’t upped the anti to match them, but I think that they are concentrating more on system wheels now, rather than just rims which has left a gap for stans products.
I guess stan's use good materials, the shorter sidewall allows material to be used where it adds strength, no eyelets - all adds up to less weight.
I remember Trek made some rims in the 90s which were lighter than mavics (and not crap) so it is possible.
yep 😀

Erm, they don't... they do a rim that's lighter and tougher than Mavic's XC rim, or they do one lighter (and quite possibly tougher) than Mavic's 'all mountain' rims, I don't think anyone would say the Crest is tougher than the Ex729 or whatever!
Mavic haven't changed their designs for years, the XC717 was the X317 which is about 15 years old, totally unchanged. DT sell carbon rims, so aren't interested in making light alu rims. Stan's fill that void!
I guess stan's use good materials,
7000 series aluminium alloy, given a fancy name, just lik eeveryone else form what I can see
the shorter sidewall allows material to be used where it adds strength,
like every other disk rim
no eyelets - all adds up to less weight.
cheep rims dont have eyelets either, do mavic and DT add them for the sake of it on high end rims? DT's road rims came out with no eyelets, then magicaly had to be improved for the next model year with the addition of eyelets as they all* failed.
*well, quite a few
I'm just not convinced that somehow a manufacturer has developed a rim that avoids the problem that everyone else has had with non eyeletted (the DT road wheels), wide/shallow section (singletracks were never known for flat spot resistance) and lightweight wheels that every other big manufacturer has had.
Think I'll stick with sensibly weighted wheels and see how the stans rims fare for a few more years. If there was something really different about them that made them lightweight and expensive I'd buy them, but I'm just not seeing it, all I can see is a bog standard rim, with the eyelets taken out (surely never a good idea IMO) and with thinner sections (if thiner is better or existing ones too thick why isn't everyone doing it)
Theres more material in the spoke bed of a stans rim. They've effectively redistributed material from the side wall, since the walls are not as tall. This is the reason they don't use eyelets - they say they're strong enough due to the extra material.
thisisnotaspoon - Memberlike every other disk rim
Really?
Your choice but I'm happy with stans after a few years' use on 2 sets (and as a previous mavic-only rimmer)
Stan's rims have shorter sidewalls than other manufacturers, it's a patented design, look at a Stan's Podium next to an XC717 Disc, they couldn't be more different. Specialized copied it with their Roval wheels and got taken to court over it.
A hell of a lot of old Mavic X517s cracked around the eyelets. I don't know a single person who's cracked a Stan's rim around the spoke hole, I had a set for several years, and I know literally hundreds of people who use them, with no ill effects.
You asked how Stans rims are better, you've been given answers, and you're disputing it, seems a bit odd! If you don't think they are, don't buy them FFS!
LOL @ SBC getting sued, oh teh ironing.
njee20 - you know hundreds of people? Aren't you a lonely & inadequate internet-resident like the rest of us? 😀
Well, I say 'know'...
I've seen hundreds of people on here post pictures with Stan's rims, I sort of know them 🙂
They're the rim of choice for racing really, the Olympic really did shift the goal posts, and the ZTR Race/Podium looks to be doing it again now they're more sensibly priced!
