Will Stan's Crests hold up?

I get all my rim dents after a blow out / snake bite when I can't stop / don't notice the flat before the wheel has thumped into some more boulders. Just leave the dents in the rims, don't seem to affect performance.

Interesting thread.
I'm thinking of replacing my DT swiss ex 5.1d rims with something that easier to get the tyre on and off. I dont have any dings in mine, but the rear is a little buckled. I am trying to decide between crests and flows, with the flows being more akin to the dt ex5.1d's that I have now.
The stans website lists the crest as for XC race and light trail use, which kind of implies to me that they'll be no good for what I want, but then theres a bikeradar review which states they've used them for 'all mountain'/fairly heavy riding for 6 months and they're still fine.
My gut feel is that they're going to be too lightweight for my riding style, but theres only one way to find out, and I;m not sure I'm willing to take the chance.

ding sidewall bent
flat spot rim is not round anymore.
apologies low res pic, best I could find.but he's trying to big it up.
why would I try to big it up?Everyones riding style is different some can finesse down a mental rocky trail on lightweight parts no problems, other tends to have a more ahem simplistic approach ie slam into/over everything, for the latter lightweight stuff may not be great. Crest are borderline lightweight I reckon.

I run Alpine's, im 12 stone and absolutly fine. although dinged it when rear tyre went flat. but its still ok and straight.
I seriously 'ragggg' my bike

Not that you'd be using a big tyre in the back of a Fuel EX 8, it wont fit
Amen to that, clearance is pisspoor on the drive side - I've wasted a load of cash on '2.2 tyres' that don't fit. To be fair they did cone up more like a 2.3 but still. Think the latest models have addressed this slightly?

Crest 29er wheels are currently tolerating my 16 stone of unsubtle style. And that is well over the rider weight limit.

"i think the general consensus is they're not far off being strong as flows when built properly, but lighter with a narrower ID"
"I am trying to decide between crests and flows"
etcHas nobody come across the arch (And arch EX)?
Stans/ZTR website has some use descriptions and cross sections here:
http://www.notubes.com/ZTR-Rims-C18.aspx
(if you click on each rim they have some other descrition)
JustRidingAlong also have some descriptions on each rimBear in mind the 21mmID 400g Arch EX is on its way to replace the 19mmID 420g Arch which should sit better between the 21mmID 340g Crest and the (perhaps? due a revamp for 2013?*) 22.6ID 470g Flow
I'm waiting on the Arch EX's (currently on Mavic XM719, hoping the little extra width should be spot on for me (width being my only real niggle with the mavics)
My interpretation (on trying to decide which to get) was that:
Crests are fine for wheels on the ground stuff and light jumps and/or light riders
(So long as you're not tw*tting them into everything)Arch(/Arch EX should) have extra stiffness due to 'braced' cross section, will take some abuse
Flow more stiffness, will take plenty more abuse. Extra internal diameter for really fat tyres (less 'needed' for many perhaps? now Arch EX is going upto same width as Easton Haven for eg)
*Purely guessing going by alpine, crest, arch EX all coming out to replace others

I think more people would take arch builds but as hope hoops aren't available like that most people plump for the crest/flow option and a hefty saving

but as hope hoops aren't available like that
yep that is a shame, maybe they'll do arch-ex hoops next year?Posted 6 months ago # -
Seems likely, the Arch EX is a great rim on paper!
a "flat spot" and a "ding" are two entirely different things Njee.
Thank you, I'm not totally stupid. My comment about Open Pros was tongue in cheek. You'd have to try pretty hard to actually 'ding' (if that's the accepted terminology) a road rim! I did however put far more 'dings' in my 717s than I have any Stan's rim, it helps that the sidewalls are a fair bit shorter, there's less material to 'ding'.

Get some 819's and be done with it!
Posted 6 months ago # -
Why? They're heavy, narrow, expensive, and hard to build on.
You can keep 'em!

do Stans spec a lower spoke tension for their rims than other makes? perhaps due to lack of eyelets?

Strong (OP's request) light (relatively), reliable and no strip-kit needed to run tubeless. They seem to stay true longer and better than any other rim I've owned. That's why I'll be putting another set on my next bike too!
There you go njee that is why I use and recommend them, you may have other criteria for your choice or wheel rim.

I take issue with "light (relatively)" - they're heavier than Flows by the time you include the rim inserts, whilst being narrower than a Crest. Compared to an anvil or boat anchor they are indeed relatively light, but in the context of XC-biased rims they really aren't.
IMO (non-tubeless) tyres inflate far more easily on Stan's rims than UST too - I think the UST is a bit of a red herring, although I admit you're guaranteed compatibility, and an increasing number of tyres are going to tubeless ready, but I'd have no faith that the 6 of so sets of (non-tubeless) Schwalbes I use would inflate with a track pump on an unmodified UST rim, whilst I know they will go straight up on either set of Stan's rims I have.
YMMV of course - so yes, we obviously have different criteria for rim purchasing!

819 is the strongest rim I've used (like I said not tried proper DH rims) but as njee says weigh a lot and narrow. Its the weight that puts me off getting one again. Got a flow and that so far seems atleast as strong but lighter.
