Industry Nine Gravity 29 Wheels - Review

Industry Nine Gravity Carbon

Industry Nine hails from Asheville, North Carolina, where the small crew of devoted wheelbuilders and machinists there manufacture every part of their wheelsets, with the exception of the rims and bearings. We picked up a set of Industry Nine's Gravity 29 wheels for a long-term test last autumn, and if you want the short version of the following review, they rocked. Our test sled was an Intense Carbine and we subjected the wheels to everything from XC/trail rides to jump sessions and DH trails with a handful of riders aboard. PB Tech editor Mike Levy reviewed the 26-inch version of the wheel on a DH bike and also reported excellent durability and performance. We normally would not post a second review of a similar wheel, but we made an exception after we discovered that the addition of Industry Nine's Gravity series wheels to a long-travel 29er trailbike could make a substantial improvement in its steering and handling. That was a story worth telling.

Construction and Options

Gravity wheels feature Industry Nine's widest rim, measuring 33.5 millimeters outside and 28.5 millimeters inside, the tubeless ready design weighs a claimed, 580 grams. The beautifully finished, 32-hole Torch hubs are made at the Industry Nine factory. Hub bearings are imported from Japan and double sealed, and the trademark Industry Nine freehub ratchet manages only three degrees of engagement delta. Both conventional ten-speed and SRAM's 11-speed HD drive systems are supported. Visually and mechanically, the feature that sets Industry Nine apart from the pre-built wheel crowd is their reversed spoke configuration. The hub's straight-pull spoke flanges are threaded to accept oversized, 2.8 by 3.0-millimeter, 7000-alloy, butted-aluminum spokes. The spoke heads seat into the inside of the rim where flanged heads of conventional spoke nipples would normally rest. The hub end of the spokes are threaded, and to ensure that the treads will not be a weak link in the wheel, they are made significantly larger in diameter than the spokes. Truing the wheels is done conventionally, with a 15-gauge spoke wrench, but directly on the flats forged into the spokes near the rim. Bold, anodized colors are a hallmark of Industry Nine's wheel range, as is the hissing sound that the six-pawl, 120-point freehub ratchet makes when the rear wheel is coasting. Standard colorways are all red or all black anodize and the weight of the pair hovers very close to 1950 grams, depending upon your choice of axle and freehub. The base price for a Gravity 29 wheelset is $1210 USD, but if you want to go wild and pick special color combinations, or chose an alternative aluminum rim, prices can range upward of $1500.

Riding impressions

Industry Nine recommends re-tensioning the wheels after the first four to six hours of use. We put six months on our Industry Nine Gravity 29 wheels without seeing any significant changes in spoke tension, rim-trueness, or bearing play. Of course, one should expect such performance from a $1200 wheelset, but 29ers are tough on wheels and that kind of longevity speaks volumes about the wheel-builders in Asheville. Our test wheels were fitted with a SRAM HD driver and were configured with 15-millimeter front and 12 x 142-millimeter rear through axles. Tires were 2.3-inch Maxxis High Roller II on both ends of the bike and run tubeless. As mentioned, the test bike was an Intense Carbine decked out in all-mountain components.

Wider is better: The wide, 28.5-millimeter ID Gravity rims slightly flattened out the tire's tread pattern, which gave the bike more edging grip in the turns and also supported the tires in the lateral directions to the extent that they tracked with razor-sharp precision. The added lateral stability afforded by the wider rims kept the tubeless tires from wallowing when pressed hard in the turns and off-angle landings. At 1950 grams, Gravity 29 wheels still hover near the lightweight end of the all-mountain segment, and as such, offer aggressive riders and enduro competitors the option to ride a rugged, DH-width rim without sacrificing much acceleration and climbing performance.

side to help even spoke tension.

Stiff and straight: Pre-built wheels are on average, quite good these days, so for our trio of test riders to be able to easily to perceive the Gravity 29's higher level of stiffness and steering stability indicates that there is something special about Industry Nine's design. Switching back to the bike's original DT Swiss wheelset, which was no slouch, further supported test riders' claims. When pushing fast and hard over rough ground, the bike remained much more calm and held a better line. The majority of riders familiar with big-wheel bikes will agree that flexible wheels and suspension components are a common theme. Gravity 29 wheels seemed like a prescription cure, with only one side effect - a weight gain of about 150 grams over some of its lightest (and more expensive) competitors. A penalty that, in light of their sweet ride, is easy to accept. The stiffness of the Industry Nine hoops is not all unicorns and rainbows though, and the trade-off is a measure of harshness that translates through the wheels into the suspension. Throw a set on a heavy DH bike and you'd probably never notice the harshness, because it will be damped by the mass of the bike and its heavy rubber, but a lightweight bike can't mask it.

Loud and proud: While you may not need only three-degrees of engagement, having such a tiny lag between pushing on the pedal and having the freehub locked in and driving forward will quickly spoil even a tech-calloused Luddite. Getting used to the loud hiss of the ratchet's six, double-toothed pawls, however, takes some time. The possible upside of Industry Nine's screaming ratchet mech is that it makes your bike sound like a dive bomber in the air - way more effective than cards in the spokes. It turned out to be quite an attention getter when test riders were sessioning jump lines.

Durability: Everything on a mountain bike can be broken, but if it is the fault of its materials or its construction, Industry Nine's warranty covers the Gravity 29 wheels for three years. So far, so good. We have yet to bash a flat spot into the aluminum Gravity rims, and our wheels are still running straight in both axes. The bearings spin smoothly, with no discernible lateral play.


Pinkbike's Take
bigquotesIndustry Nine's Gravity 29 wheels give big-wheel riders the precise, sharp-feeling steering and line-holding power that we have come to expect from the most admired small-wheel bikes. If you are looking for an alternative to carbon, and subscribe to the wider-is-better theory of wheel design, Industry Nine has micro-engineered a durable and very elegant looking solution in aluminum. There are lighter weight options for all-mountain 29ers available from Industry Nine, as well as from its competitors, and we have ridden many of them, but there is some sort of magic in the Gravity 29 wheels that makes them standouts. Those willing to overlook a handful of grams in exchange for a heap of high-speed stability should get their hands on a pair. - RC

 @Richardcunningham I know they are. I've ridden them in both 26 and 27.5. Not extensively, but enough to know they are good. Stiffer than the Havoc UST wheels I'm running now, at only $100 more.
I respect that you know what you're talking about. I was merely taking issue with some of your articles, in which you seem to put a slightly rosier spin on the performance of the product. I know that if any reviewer gets a rep for ragging on the parts they review, that companies won't want that person to do a write-up. This isn't the case, because I9 makes the best alloy wheels on the market, but a little more of "calling a spade, a spade" wouldn't be unwelcome from this reader.

 The issue is pinkbike is headed the way of mountain bike action. Rosy reviews for advertising dollars. That was my biggest fear when rc came on board and it looks like it's going that way to some degree. Only reviews of high end parts and bikes. All bikes climb like mountain goats on steroids and coner like they're on rails etc. MBA had zero integrity review wise and I'd hate for pb to go the same way

 For those of us who as been riding for over 20 year we have seen the industry have this crazy evolution from heavy hardtail to full carbon dh rig...RC has been one of the top reporter/ bike tester since the beginning of the mountain bike movement...I remember reading MBA and being always stoke about the new product...RC probably tested more product in his life than anybody else...If you don't like the author of the article, don't reed it....There is many other biking site that will enjoy debate with no content about 27.5, 29 inch, and wearing enduro helmet with goggles...
the rest of us will continue to appreciate reading an article wrote by somebody who's passionate and a pioneer to the sport and give proper review.

If RC choose to test a product and says that it's good...Well I trust him as nobody else on this site, or any other site, can tell me or prove me that he tested as many wheel, bike, shock fork, and do a proper comparaison as RC does...

Props to you RC... Still enjoying reading your review!

 The wheelbuilders at Industry Nine are skilled artisans. One of them built my conventional wheelset (with Enve rims) just prior to getting hired at I-9, and I have needed to trued them ONCE in the last season and a half.

...and most of the employees there are rippers and fanatical bike enthusiasts. it shows, as their product is killer.
  • + 2
 I've had a set of I9 Torch Trails for a little less than a year. Totally burly enough for rough AM... They're true, and spoke tension has remained unchanged. I ride a 30lb 6" 29er, so weight isn't really a concern of mine, but they're pretty damn light, too, except when I put 1100g tires on them. Noticeably stiffer than the Hadley/Flow EX wheels they replaced. Great CS, as well. Love these wheels.
  • + 1
 I've been running an I9 SS hubset/ZTR Flow EX 29 rim combo for almost two years now. Wouldn't want anything else. They're yet to need truing, despite me casing the rims on roots and rocks countless times. Had to replace the front rim after a crash that bent (compressed) the front end of my (steel) frame as well as pinch a hole through a knob of the front tyre and take a chunk of metal out of the bead hook of the rim, but the wheel stayed perfectly true until it was de-tensioned.
  • + 1
 That more likely has to do with carbon rims needing very little truing- if they bend out of shape permanently, they have or will shatter. The extra stiffness prevents nipples from coming out of contact with the rim so much and thereby loosening.

 product is killer, BUT PUT DOWN THE BONG AND ANSWER THE PHONE I9!!!

 The first time I went to any half decent mountains was in North Carolina in 2004. I test rode a Turner 5 spot with I9 hubs that were anodised green. I have lusted for them ever since.

 The price and weight of these wheels is a joke. For a few hundred more you can get lighter, stronger, wider, carbon wheels. Wheelsets in general are too expensive. Especially from companies like this... Hell I can get a complete bike for cheaper than this wheelset. How does that make sense material wise? If you aren't manufacturing your own hoops anyways why am I paying so much? It makes no sense? There are similar hubs out there that you can build wheelsets around and stay south of the price of these, easy.
  • + 2
 Flex, man, you're paying to reduce the flex. Watch some of the aggressive 29er vids on here in slo mo and you'll see just how much flex is engineered into wagon wheels. I still think the price is insane, but seems like you need to spend a ton in big wheels to get stiffness.
  • - 1
 I disagree. I think the best wheels you can buy for the money spent at Stan's Flows. Half the price of these, good engagement, solid as hell. Interchangeable from bike to bike. I've offered customers Enve AM wheels for $1800 bucks out the door. I think that is a much better wheel that the I9 which weights almost 400 grams more. Better options to look into at the super wide Mavic rims built around like a DT 240 hub... Thatd be lighter and probably as stiff. and cheaper! I'm sorry but a 1950 gram wheelset that cost $1500+ is just a big HELL NO for me. I'll stick with my Enve AMs. Wider, stiffer, and much much lighter.

 rims are cheap. It's all the machining that goes into the hubs. You could get a "cheap" carbon rim laced to another hub for a similar price but if you want a high quality hub you have to pay for it.

 Axxe, Ive ridden both, hard. Stan's held up better.

 Some of the best hubs out there can be built into a very nice wheel-set with great rims and standard spokes for significantly less. For the similar price, I would rather have DT 240 or Hadley on Derby rims laced by a guy I know..
  • + 1
 T-wood: Most reviews, and my personal experience is that Frequency holds up just as well. Frequency had a few reported failures before WT69 alloy, but nothing negative I can find since. I only used WT69. According to wheelbuilders I trust they build up better, with their directional spoke drilling, and they have UST compliant bead shape so they fit more tires better and do not stress them in non standard way as BST bead does. I am done with Stan's since they went to EX series - no need for tricks to run non-tubeless tires anymore.
  • + 0
 Axxe, I've been working in a shop for some time now. I've ridden several 29er platforms, both hardtail and full squish with several wheels, tires, drivetrains etc etc. You can reiterate what sold you on products to me that's fine, but wrenching all day long and actually using products, I have my own experience, and know what works well and what doesn't. I like WTB, don't get me wrong. but I think Stan's is better bang for the buck. I've ridden Flow's and Arch's super hard, as well as WTB i23s laced to 350 hubs. I started to see more wear on the WTB's than the Stans I've ridden. Just saying, in my experience and in my opinion what is what. I agree to disagree... my overall point, these wheels are a rip-off compared to what else is out there, you seem to agree with that...
  • + 1
 @T-Woot: Clearly the hubs do not cost $1,500. That is ignorant. The hubs are pricey as well as the machined spokes. Then you have the cost of the rim and labor to build them and at that they are still not $1,500 if you stick with stock color options. People could say the same to you about purchasing a rim that cost close to $1,000 and then you still need the hub, spokes and labor to build it. No one is forcing anyone to purchase them. If you don't feel like you can justify that then don't. I personally am a huge fan of them and have had nothing but great luck and customer service from I9 anytime I had a question or needed something. I have mine laced up to Flow-EX rims. I've had a set for DH and a set now for my AM bike and they have been bomb proof. Are the hubs pricey? Sure but they are top notch stuff.
  • + 2
 @T-woot : You can refer to your own experience, but I trust builders I know and I trust facts. Differences I have listed are a fact, not an anecdotal opinion. Personally, I can't tell the difference when riding. But industry standard bead shape and seat diameter, spoke drilling, service history are far more indicative than somebody riding it "hard". And I am not saying bad things about Stan's, had been a user since they came out... just moved on with a new option.
  • + 0
 I never said the hubs costs 1500$ you basically did.. If you read my comment correctly. I was saying the hubs aren't worth anywhere near it. Everything in this industry is machined. With the shop taking their cut, the vendors taking their cut then these companies earning theirs. the mark-up on JUNK like this is huge. They are self-proclaimed top-notch hubs. They want to you to say that FOR THEM. In reality it cost not much more than a lot of other products out there. If you want a good hub, get a White Industry.
  • + 0
 Axxe, I'm not going off what I have ridden hard, but rather a whole array of customers, what they have used. What racers use, what reps use. So on and so on. I've built wheels, my mechanic builds a ton of wheels.... I talk to reps. Go to interbike get the low down. Then add in my own experience. I've already stated this in my gathered opinion and where it comes from. Again, I agree to disagree. If you want to shovel out that much money for a heavy wheelset go for it. Just not for me.
  • + 0
 Heavy wheelset? Wut? They are about the same weight rim, about the same width (for mid width option on WTB). They do cost less. And you did not refute any of the facts. a) There is no evidence that Flows are stronger b) Directional drilling builds up easier, every reputable builder will agree c) EX tiny bead has non standard seat diameter that no tires are designed for. Yes, it works, but that does not make it a better option for a casual user - it is far, far easier to fit and sit a tire on UST bead, without any trial and error (Tried any Geax on Stan's recently?).
  • + 0
 You are not stated any facts. You are stating you think WTB is stronger than stans and that you think tires mount betting on WTB hoops. You make no sense. You drank coolaid I get it. Oh and yes, I actually just sold my stans arch ex 29er wheelset and removed my geax saguro TNT tire no problem, after mounting it no problem. Sorry I cant respond to you fast enough. I'm too buy managing a bike shop.
  • + 1
 I did not state any facts? I even enumerated them for you, for simplicity.
  • + 0
 Bead Diameter, and spoke direction can be a factor, do they determine the strength of a rim, maybe maybe not. Wheel builder also have different opinions. I've see more frequency's get banged up over flows, that is what I've seen.... I-beam construction is good and stiff, the flows profile has a wider ID which might make them, well better, again opinion. If I were looking for a good pair of wheels to spend money on, I think those are a great option. As are Frequency's built onto 350 hubs per say. I've ran both. I liked both, I never flat spotted the ZTR Flows though. Beyond the point of that debate, my original comment was delivered to this thread. I was saying there are wheel-sets out there, for a fraction of the cost of this one, that are pretty dang stiff with relatively good hub quality. These wheels are flashier and different, and pretty stiff, I have seen some spokes that need some attention as the article stated. Regardless you can build other wheels with better or equal hubs to I9 and still come in cheaper and about as stiff. I've eyed out I9's. Worked on some, sold some. That's where I am coming in on the great wheel debate. I am going off of, again, customers bikes, industry, and my own experience which fact(s) or no fact(s) included. Is just an opinion.

 I got some of the torch hubs with the trad flange laced to some Flow Ex rims and they are the best wheel set Ive ever had. Probably speaks a lot for the guy that built them for me but I have been very hard on them and still no issues. When looking at building them up I opted for some straight gauge dt spokes (champion I think) as I had friend with some of the I9 spokes and although they look great are a real pain when you break them in the middle of nowhere. The thing about them I love the most is the engagement. Techy spots in the climb that used to stop me are now easily climbed and pedal strikes are avoided with a simple back pedal and instant engagement to get up and over stuff. I'm with you on the price but the stans retail for $100 a piece and the hubs for $600usd I think depending on the color. So you could build up a set under $1k USD if you dont mind not having that extra bling factor. The set is not for anyone whos looking to avoid making noise. Jesus they are loud, EVERYONE knows when you're either in the air or being lazy and coasting.

 If you ride a bigger wheel the stiffness these provide are addictive. If you live in technical riding spots, the engagement from the hub is a must have. King might have engagement but they don't build as stiff and predictable as these.

 I enjoy riding fun technical docents, excited to see what the 29er will handle noticed that at speed I got out shape quickly saved a few then ended up Destroying 2 DT Swiss M540 wheel sets, big crashes, 1 resulting in a trip to Urgent care. Finally healed up stoked to get back on the horse, on my Intense Carbine 29er equipped with the Gravity I9s'. Right off the bat noticed the buzz and the instant engagement from the rear hub, at speed and technical sections they keep there line and are very stable due to the width of the rims 33.5mm, mashing through chunk I rarely heard a rim ding. The only draw back which is not that bad, is that there's a tiny bit of drag due to the engagement of the rear hub. bottom line if you ride the technical terrain and love speed, you'll love the stability and reliability of the Gravity I9 29er wheel set.

 I've had a set of i9's for a few months now and I must say they are well worth the money. The stiffness is amazing and the amount of momentum these wheels carry is unbelieveable. Completely changed how my bike feels. I live in Asheville and the folks at i9 offer great support and service on their products. They are helpful with questions and care about making sure you have exactly what you need to make your riding experience quality. Good folks over there. And for those dismissing these wheels just based on the price, I suggest you ride a set before you comment further. You'll know exactly where your money is going.

 I use the industry 9 hubs WOW the rear is brill 120 point of engagement with 6 paws just keeps the power on on on really does help on climbs .infact I had a hope t.rex 40tooth convertor on my 11-36 cassette and now I've removed the 40 T.rex ring as I've found the i9 rear hub give such a big boost in power transfer is hard to beleave until you try them . The sound does drive you nuts more so on long rides but add a tiny bit of oil inside the free hub and it's much better to live with . Best hubs I've ever used . So if you ever get chance give them ago .

 I had a pair of I9 wheels on my DH bike for 2 years. Living here in the UK it was an absolute nightmare! trying to get the parts when things broke....and oh how they did. The freehub pawls had these really odd 'springs' which would just bend all the time and the tiny bolt holding them in would always round off. In addition to this I broke plenty of spokes (Which were £4.50 EACH) mostly they would snap just above the hub but there was always the additional worry about stones flicking up and taking chunks out of them. That said, the wheels looked sweet and made the freehub made the most amazing sound.
Eventually I sold them on and got some hope pro 2's with 729s and have never looked back.

 Hudders, I had a pair as well, beautiful looking wheels I had the killer green hub and spoke combo, they rode really well. The rims were easily knocked out of true and the spokes constantly came loose and I had them professionaly tensioned as recommended ?? I've had much better luck with Mavic rims and other hub combos. Too bad they looked like rolling sex. For $1200, I've had better reliability on stock Roval rims and DT Swiss hubs that cost half ??

 They look awesome but they are not any wider, stiffer, cheaper, or lighter than my derby carbon rims laced to 40 tooth hopes. Pinkbike should test some Derby rims!

 ^^^Got a set in the test lineup. Also, the new Ibis Carbon wheels use the same rims as Derby. Good stuff.

 Just put I9 Enduros on my Specialized Enduro 29. Very stiff and responsive. If you rider 29ers you gotta have a laterally stiff wheel. It makes a big difference.

 Also Tracey Moseley won the EWS riding a 29er at some rounds (maybe every round- I can't remember), and I'm sure she had a lot of bikes to choose from.

There's plenty of evidence to suggest they work well going downhill aggressively for some riders, but obviously not everyone

 Your spot on elbandido - every round I believe - in fairness she'd have still won one a BMX, an incredibly smooth rider there!

 I'm not sure why RC says that " 29ers are tough on wheels" when 29ers are actually less than smaller size wheels as they have roll over better... less impacts. Science!
  • + 1
 Jaydawg69^^^ the spokes are longer and, due to the larger diameter wheel, the angle that they intersect the hub is flatter. Those aspects create a more flexible and laterally weaker wheel (if all the components are of similar construction.) The leverage moment created by the larger diameter also adds more stress to the wheel components. IN addition, the longer fork for the same travel adds some flex to the equation. While the roll-over is better (you hit that on the money) and may reduce stress on the wheel, landing to flat is the same and lateral forces are more destructive to 29er hoops.
  • + 1
 landing to flat is true, but 99% of damage to rims is from impacts. The 29er lessens the impact, hence the rims hold up better overall. Spokes are cheap to replace and fairly easy to do, hence I don't count them as being an issue overall.

 I put some i9's on my covert last year, retentioned them once like any new wheel set and haven't had to think about them once other than that. Super stiff too.

 I love my I9 wheels except I have to replace the free hub every couple years because the cassette eats into it and starts to creak.

 I have to do this with my Hope hubs too... Al freehub bodies will always do that.

 I bought a set of these wheels less than 1 year ago and they turned out to be the biggest waste of money I've ever wasted.
Totally overhyped, overpriced, poorly designed, poor customer service was my conclusion after all the issues I had with the wheels and the company:

Bearings were worn/rough on the wheels BRAND NEW OUT OF THE BOX! I9 said "oh, we may have received a bad batch of bearings from Enduro with a grease seperation issue" - really? How does grease seperate in a sealed bearing exactly?
Did they not even check the assembled freehub? Of course not - they're I9 and they're "top quality" - they'd never produce anything that would not meet their lofty quality standards!

 ....
I9: "It seems that their is a chance some of the bearings with bad grease may have had the separation occur gradually over time, so we may have shipped some bearing out that had the separation issue while the wheels were being warehoused/shipped after being boxed up."
Zero spare spokes shipped with wheels.
Half the back wheel lost tension on the 2nd spin, several broken spokes, build quality was rubbish
Had to pay to get them re-built.
Requested spare spokes, told they'd be shipped to the UK Disti when they were making their next order - in a few months!!!
Freehub fell off the wheel when changing a tyre on the trail - lost pawls and springs (a design problem with the axle they said - really? and I'm the guinea pig that has to find your mistakes for you?) spent AGES searching for the tiny springs and pawls.
Bearings collapsed in the hub
Bearings collapsed in the freehub - freehub ended-up being redesigned - yet another design f**k-up from I9
Apparently got a new freehub sent to me which never arrived, requested another which eventually arrived after me having to convince them to send it to me DIRECTLY and not to the disti - what part of DIRECT FAST customer service do these guys not understand?
6 weeks without the bike, new freehub wasn't even supplied with any springs or pawls - margins must be REAL tight at I9, or else they're just plain mean!

In total over 60 emails between me, the disti, and I9 to get all the problems sorted.
I'd never go near any of their stuff again.

 Spare spokes from i9 retail for $6 and the wheels come with 2 spare spokes. Mavic spokes retail around $10 and you don't get any free with a wheelset from mavic.

 Hey RC,

Wouldn't the enduro torch wheels be a better lighter option for most 29 inch bikes out there?
  • + 2
 Diville64^^^ I would have thought so too, and I'd choose a lighter setup because I don't but a lot of torsion into the chassis when I ride. A lot of technical riders do and, it's the stiffer wheel that seems to be the difference for AM/trail 29er perfomance - that's why I posted the review. I went through a few 29ers, testing over the last six months, and was riding Stans ZTR, American Classic AM, the new DT Swiss wheels and Enve, They aren't lightweights, but Judged by their steering and turning feel, the I-9 Gravity wheels were at the top of the class. That said, I understand that some of those are not apples to apples comparisons, but they are wheels that many are familiar with. The two men I most often use for comparison are pretty good DH riders and both reported similar results.

 Awesome thanks for the reply. I was asking only because I'm running the i9 enduro torch and they are every bit as stiff as my Easton haven carbons I came off of. I weigh 225lbs and take awful lines. I'm pretty much a crappy rider and these are mind blowing. Good review as usual!

 So true them, it's easy. All new wheels will have their spokes come loose after the first couple of rides. They have to stretch and bed in.

 Just make sure to check tension after the first ride and you'll be good. Best wheels I've ever had. Love my gravity 26s and trail 27.5s. Just about a year of riding on the gravitys and still perfectly true, with a fair amount of racing and jumping.
