stans no tubes 29er ztr gold wheels

I am a similar weight to you, and am actually quite light on wheels. I have tried them and although they stand up (i.e. they havent collapsed under me) they are very very flexy.
a very good female friend of mine rides them (and ironically - if you arent convinced by me - has a set for sale 2nd hand) and she weighs 54kg. She has had no issues with them other than in a crash, she bent one. They have required a bit of tensioning of spokes etc.
I'd be honest and tell you that you would probably go faster (I assume the purpose of the purchase) on a stiffer, but still light set of Crests.

Consider also the tyre choice you make. The Race Golds are about 1320grms. The Crests can be about 1420grms. 50grams at each end. I honestly would say that running the Crests, and one less cup of sealant to keep the weight down, would be a better strategy.

Unless you are desperate - in which case, send me a PM and I'll get you a pair for about $500-$600 (not mine to sell, so am just guessing).

After using my brain i am pretty sure these wheels are going to be too light for me, and i have also been looking into the Crests, cheaper and also not that much heavier, possibly much stiff, so i think i will go with them. I have a AM trek that I use to race so it isnt the lightest bike and i am most certainly not the smoothest rider out there, i have been known to hit all the jumps/make my own on the 50km races i have been doing.
my current wheel set is 1950g, so if i get lighter rims and tires i think i can save plenty.

I'm loving my ZTR Crests.... 29er with Stans and FastTrak Speshy 2012's....I'm 76kg... given these rims a real run over the last 6 months...., they're really really fast and they held up so well to the punishment I've meted out

was a weird feeling when you wind them up and they just keep rollin rollin rollin... its like i had a small flywheel thing going n

Having experienced both Stans 3.30 and Hope Pro 2 hubs I can only say that the Hopes seem to pick up slightly faster than Stans'... but that could be that I have the Stans hubs on a 29er and the hopes were on a 26er.

I have absolutely no complaints with Stans hubs. They are easy to service, rugged enough for what I throw at them, and haven't yet needed any attention other than cleaning and greasing the freehub.

So the only differentiator for me is budget versus bling. If they were $ for $ I'd get Hopes on my next wheeelbuild jsut for the bling.

I have a fair bit of experience with them both. The Hope hubs are a lot better. They are easier to get spares for (axles, bearings, freehub bodies) and also easier to service. They are a bit heavier, but significantly tougher.
If its a race only wheel, then go Stans. If its a few types of rides, then go Hope.
However, better than both of them are DT Swiss hubs. Maybe a '340' series would cost as much as a Hope set-up? Not sure on prices. 240's are the king of hubs but I think are more than Hope.

FWIW - I have a second set of wheels myself - Hope's with Arch rims - that I train on. The Hope hubs have been rebuilt now with 3 different sets of rims over the last 5 years. I got them as a 9mm QR, and they got changed (very easy - did it at home) to 142x12 about a year ago.

Re the noise of Hopes, just ensure that there is sufficient light grease in the freehub, and they wont be loud.

I seem to be doing a lot of freewheeling in my 50km races, i am rather slow to start, so that might help me!!

Thanks for all the thoughts and comments from everyone, very helpful.
I think i have decided to go with the hope or 3.30ti stans hub(if i can get these in 15mm thru axle) and the crest rim, should be pretty sweet!
