I think you got a bad pair then. I've had mine since April, and they're my only wheels, so they cop a fair beating. No flatspots (unlike my 721s) and no cracking around the eyelets (unlike my friend's 721s). I also weigh 120 kilos. And I hit stuff pretty hard.5.1s are like butter. They bend just by looking at them wrong. They are waaaaaaaay to expensive for how soft they are.
that must mean there aren't many rocks where you ride. I've tried FR 2350 and EX 1750 wheelsets and both dented/flat spotted on my first day on them.I think you got a bad pair then.

nah it was a rock. I did try to bring it back with pliers but the rim was so out of round that it wouldn't matter.acadian, this bend is made by something else but a rock! (pliers maybe)
LOLOL - kidwoo just sat on my bike and bent those :huh:tried the same with a 6.1...
it broke like choclate...
I've been battering a pair of 5.1s on my "do-it-all" bike for the past couple months and they haven't had any issues at all, nothing like the buttery-soft 6.1s. I'd not have any problems running them on a full-blown DH bike, they're very light and seemingly pretty strong.I think you got a bad pair then.

IMO, I'd be running 5.1s on a 240 front hub, 440 rear (150) with DT Revo's or bladed sapim CX-Rays. I don't see why you couldn't use it for more than racing either (obviously with brass nipples, not aluminium ones).
My GF has King hubs on her trail bike. Pink; X-mas gift from me!have never had a problem with engagement or lack thereof with any hope hub i've ever owned
I heard a rumor that the World Cup guys go through several 5.1s in a weekend because the rims are intentionaly soft. The rim giving way is supposed to help avoid pinch flats. Just what I heard, I have no idea if that has any truth to it. I have a set of ex 1750s (5.1s), and I'm happy with them. A couple minor dents, but nothing I didn't deserve. I should add, no flats this season so far.
Alloy nipples are fine as long as you grease the head of the nipple (where it rests against the inside of the rim) and use anti-seize, blue loc-tite or spoke prep on the spoke threads. You might have to replace one or two nipples every now and again but that's not a big deal. There are a lot of places I'd elect NOT to save weight before NOT choosing alloy nipples. If you're trying to get your bike as light as possible every bit counts. It all adds up....dude, it don't kow about alloy nipples... with all the stress of dh i'd think they would strip. another 20grams for brass might be worth it.

Trying to understand you on this one, If I assume correctly you think Hadleys have faster engagement then the I9's. If thats the case, no they dont. The I9's are faster than kings and hadleys. I have had 2 sets of kings and rode another set of the 108 hadleys before getting 2 sets of I9's.Mine really like to dent and pinch flat. I dominated some 5.1s but they're fine for trailriding or dirt jumping, they're on my hardtail now.
Just picked up another set of Industry Nines and I could notice the engagement coming from a hadley. Granted I've been on my other set of I9s for almost two years so I already knew what I was missing.
Thanks for the info. I tried to find that a while back and I couldn't. I've got a spare set at home and I think I'm going to use them to build up a FR wheelset. I had issues with the front and rear hubs that came with my outlaws but the rims have always stayed true.Just wieghed a Outlaw rim and its 560grams. WTF
No that was the red pair.LOLOL - kidwoo just sat on my bike and bent those :huh:
that red pair of wheels you tired used 6.1 rimsNo that was the red pair.
My rear wheel was fine, but the front wheel couldn't take it. After around the 8th nipple that had broken and had to be replaced the first month we just replaced them all with the brass nipples.Word.
My alloy nips are great after a year of running too-low pressure in SB and around Socal, not prepping them, and occasionally truing the wheels.
I just looked at the I9 website and here is what it says:Trying to understand you on this one, If I assume correctly you think Hadleys have faster engagement then the I9's. If thats the case, no they dont. The I9's are faster than kings and hadleys.
Maybe?:huh:My GF has King hubs on her trail bike. Pink; X-mas gift from me!
She bought the Pro II's to build for her light bike becsue they were so much cheaper than the King's. First ride she was telling me she thought the chain was skipping or that somethig was wrong. I checked and couldn't find anything wrong? After her telling me this a few times I figured out that her complaint was the lack of engagement.
She is not a super mechanical person but she noticed first ride. Maybe I don't give her enough credt?
I just looked at the I9 website and here is what it says:
"Holy 120 engagement points! How strong is your drive mechanism?
The Industry Nine drive mechanism is a fairly simple, tried-and-true pawl arrangement. When engaged, each of the three driving pawls itself has three points, providing nine points of contact to the hardened A2 drive ring. The drive ring has 60 teeth, which would normally allow a 6-degree engagement among the fastest in the industry. Our proprietary mechanism allows for a second set of three pawls, phased three degrees from the first. This feature cuts engagement time in half, to a mind-blowing three degrees! Our lightning quick take-up has become highly desirable on singlespeeds, twenty-niners, and disciplines with gate starts. We have tested our drive system beyond 700 ft-lbs of torque, which amounts roughly to a super-chipped Ford Power Stroke turbo diesel engine. In over two years of prototyping and testing, we have had zero drive mechanism failures."
On paper that has to be the highest engagement count out there! But I have not ridden them so I have no personal experience. But 120points?!?
I shift hard and weigh 230lbs now, I have smashed them, rammed them and just this side of torching them and they are almost instataneous engagement. I rode another persons bike and felt like the drive train was goofy or his chain was stretched out, turns out it was the engagement on the rear. So I would be disappointed to ride anything else. My tubeless set up has all 6 pawls and my DH set up is running 3 and they are both spot on. LOVE I9'S, greatest set up so far.I just looked at the I9 website and here is what it says:

The one complaint (besides price) I have heard about Kings is that they have built in drag. Are the I9's like that with all the pawls?i love mine. but i took out 3 of the 6 pawls to reduce friction.
i still have 60 points. they work 3 at a time.
Those are XC wheels, not DH wheels.i run:
Mavic EX819
Hope Bulb / Hope XC (ti spindle)
Sapim CX Ray Spokes.
I don't think it gets lighter.

The Kings and Hadleys are 72pt no? So 60 is still a world better than Hope II's at 36pt?
Industry 9 does not have the fastest engagement out there. That title belongs to True Precision Stealth hubs which feature an instantaneous engagement system.I just looked at the I9 website and here is what it says:

Why do you have 3 rotor bolts?I don't care about the weight of my wheels:
Is it bad that I do not know how heavy my stuff is?
If you're 110# after 3 pints of beer so yeah the 819 would hold up... May be. The 819 is a great wheel but we got to be realistic here. 90% of the people would smash this wheel in days. Most of the DH courses I saw in the french alps had pretty tame trails rock wise. In Les gets you probably can count rocks on one hand. Even on the Avalanche cup course in Oz en Oisans you rarely hit rocks head on. Ride a place like Schweitzer on the 819 then we'll say yes. they are downhill worthy!oops. guess i shouldn't have ridden north shore and the french alps for weeks, including several avalanche cup courses and some of the gnarliest dh known......
seem alright to me.
I lost 3 in transit to St. Anne. I was ghetto-rollin'at the world cup.Why do you have 3 rotor bolts?
