PRESS RELEASE: Industry Nine

Industry Nine is proud to announce the Hydra Grade 300 v2 wheelset, designed to deliver on the biggest hits, deepest sends, and eMTB rips. The standout feature of this wheelset is the all-new Grade 300 alloy rim, incorporating hollow bead wall technology—a triple cavity design that reduces pinch flats and enhances impact resistance.


Increasing the bead wall width 78% helps eliminate concentrated tire pinch points found in conventional hook-shaped rims that can lead to pinch flats. Additionally, the triple cavity rim section enhances the structure’s strength and support, significantly reducing the severity of impact deformations.

In-house testing revealed that the new Grade 300 v2 impressively outperformed the previous generation rim. Regarding bead shelf deformation, the Grade 300 v2 exhibited a 79% improvement under moderate impact and a 65% improvement under severe impact. In terms of bead wall deformation under the same impacts, the Grade 300 v2 showed a 72% improvement under moderate impact and a 66% improvement under severe impact. Furthermore, the associated spoke tension drop at the impact site was also reduced, with a 62% improvement under moderate impact and a 71% improvement under severe impact. Industry Nine confidently asserts that the Grade 300 v2 is the strongest alloy rim they have ever offered.

Built on the Hydra 32h system hub and spoke chassis, the Grade 300 v2 wheelsets feature the iconic .52° engagement freehub system combined with direct-thread hubshells utilizing a one-piece machined alloy spoke, creating a ride quality and customizable aesthetics unlike anything on the market.

The Hydra Grade 300 v2 is the most robust alloy-rimmed wheelset in the Hydra custom alloy line. It is specifically designed for downhill bikes, bike park builds, and eMTB use.

A note on Hydra axles:
Industry Nine prioritizes rider feedback, making continuous improvements in our products a focus. When a small percentage of riders reported durability issues with our one-piece axle, we initiated a revision and testing process. The revised axle integrates a washer to mitigate the stress riser on the driveside axle shoulder on Boost and Superboost hubs. After confirming the revised design's reliability and observing no repeat issues during testing, we integrated the improved two-piece axle into our full-scale Hydra production. From June 2023 to current builds, every Hydra Boost and Superboost wheelset and hubset has utilized the revised two-piece axle.

 Am I missing something here? 1430 for alloy wheels??? Sc reserves are half this price with a pretty comprehensive lifetime warranty

 may as well buy the carbon reserves at that price

 Agree, I think they missed the mark with the price range.

 The alloy spoke system is very stiff - and expensive, spokes are like $5 a piece. I'd say its worth it though, the alloy spokes build up really strong wheels.

Carbon rims are not the end all for rim design honestly. Running carbon rims for the average person means running inserts to protect your investment... i have gone through a few carbon rims. An aluminum rim with an insert feels about the same as a carbon rim with an insert. The weight difference and stiffness difference is negligible compared to the difference an insert makes in feel.

 @R-trailking-S: Maybe I had the wrong wheelset, but the Enduro S wheelset was pretty awful. I went through three 3 rims in a year (with Cush DH and a heavy casing tires). Switched to DT Swiss EX511's and haven't had ANY issues at all.

 @R-trailking-S: Not for me... after running running alloy I just got tired of denting the shit out of rear rims. I'd rather not run inserts, I just hate dealing with them and love the easy breezy-ness of no inserts. But even with a DH tire and 30psi, I still dent rims. If the rim made it to the end of the season, it usually had 3 or 4 dents and was more square than round. I would also only be offered crash replacement discounts.

Finally switched to carbon, the rims are about the same weight, but with no insert and a double down tire, my rear wheel is considerably lighter. Year and half in and I've bashed the shit out of these rims = zero issues, straight and true. Plus, if I do destroy one, the no questions asked free lifetime replacement has me covered.

Just for the durability alone carbon makes so much sense.

 @dmackyaheard: i use DT541s myself. I have had to true them less than any carbon rim i have used for park riding. No dents with rimpacts.

Interesting to hear about the I9 rims on the trail. I have only worked on a set, but the alloy spokes themselves true up really well, even with rim damage. Much more solid than regular spokes

 Aluminium? I agree! They should have made it from the same metal as Thor’s hammer!

Although I don’t know what the warranty is like on that

 @HaroldCDN: that used to me a few years ago. Always used to wonder how people destroyed wheels as I’d barely ever had a dent. Got fitter, stronger, much faster and much better. It started to just become part of riding… until I went carbon.

 @Symmech: carbonfan, nextie, light bicycle. A couple other off brand carbon rims. Nextie has been reliable so far, but the cost on WAO is out of the budget for something that has always ended up being a wear item that gets slapped around by slabs of dolomite, limetone and sandstone. Generally, failure mode has been delamination in the body, not from rim strikes at the hook/bead area.

 I used to drool over i9s but recently I kinda love DT wheels, love the FR1900s on my DH bike

 Same. You can't beat DT for making your geared wheels single speed and vice versa.

 @erikhortsch: @DylanZ91: I’d bet dollars to donuts most people with i9 bearing problems had them over pressed. My first set lasted 3 years, had some new ones installed getting wheels rebuilt, lasted a week, I installed another set careful not to over press and no problems again
  • 4 1
 But will the axles still break 9 out of 10 Times?!? Asking for multiple friends
  • 6 1
 I also used to drool over I9's until I bought a set a few years ago. The bearings lasted only a few months dealing with UK weather conditions. When your riding muddy trails 10-12 months a year, a pair of wheels designed and tested in a dry climate is never a good idea.

 @DizzyNinja: 4 sets of hydras in my family. We ride snowshoe mostly in the summer so lots of mud and slop. Still they eat bearings and at $60 a pop it adds up. I started pulling the seals when new annd repacking with waterproof grease. It’s helps some but Anybody got a bearing option that seals better? My wife’s dh bike has the crapiest e-13 hubs and the bearings are still good after 4 seasons.

 @Jackharmer: I will say that to counter the lack of bearing life, I have been running grade 300 wheels for 4 seasons on my dh bike and not even a dent or flat spot on the rims. They hold up and ride great, just the bearings disintegrating twice per year blows. I Wonder if better sealing end caps would help?

 How about some bearings that last longer than 2 weeks?

 If the intended use is primarily DH, surely they should incorporate a wider flange offset with a 7sp freehub? similar to Hope Pro 4/5 DH rear hub.
I personally, would not spend money to buy a i9 "DH specific" hub which is designed for 11/12sp cassettes.

 Returned an I9 hub with a broken axle under warranty. They pounded out the bearing replaced the axle and pounded in the old bearing. . . . . . Industry nine is a joke ! ! !

 starting at $1,430 for aluminum wheelset, is this April fools? Who the heck is going to buy these? I had my local shop build up a set of wheels for me last year, i9 1/1 hubs with dt ex511 rims, FAR cheaper than these would be, and they've been flawless.

 Came here to say some things and as I read all the comments about problems and complaints and DRAG.
They have all been said: Over-priced, Over-hyped, Over-problematic... I'm Over it
  • 2 0
 The price of carbon, the weight of a set of prebuilt DTs, proprietary parts that don't work any better but are harder to source (and good luck ever getting a true color match on anodized parts). And finally......a reluctant admission that maybe juuuuust maybe the axle design was poorly engineered. To be fair, i9 stuff isn't BAD, but it isn't great either. At the prices they charge, their stuff should be better. And forged not machined whenever possible.

Cool new wheels! Site error listed below:

The grade 300 v2 wheel weights are exactly the same as the Enduro 300. This PR says they should be higher.

For example 27.5 should be 1990g not 1800g. You might want to check and make sure the numbers are correct.

 Lots of complaints here, but I’ve been on i9 since 2018. The only problem I’ve had is when I bent a derailleur hanger, and sent a chain into the spokes and broke 3. I was on vacation in Moab, and they offered to overnight the spokes to me at closing time on Friday so I could get back up and ride. So my experience has been excellent customer service.

Beyond that, though, I’ve had zero problems. That first set of wheels was the Enduro 305s on Torch hubs. (Everyone seems to like the Torch hubs). About the strongest, stiffest, truest aluminum wheels I’ve ever had. I think those cost about the same as these, so factoring in inflation, these new ones are actually a better value.

Second set of wheels are Hydra hubs laced to We Are One Union rims for three seasons. Again, zero problems. No broken axles, no broken bearings. Maybe the wheel builder put in a better axle ahead of time, I don’t know. I’m not heavy, and I’m not light (180-185 pounds with riding gear?). I ride a lot. Maybe I take better care of my stuff, maybe I’m Mr. Smooth out there, maybe I’m just not as rad and gnarly as the rest of you, but I hear of all these bad axles and bearings, and it’s like you’re all from another planet based on my experience.

 usually people with problems are the anomaly, but in the case of i9 customers, YOU are the anomaly

 In the pecking order, DT sets the gold standard for reliability (and maybe Chris King). i9 is second tier stuff, along with Hope and Shimano. Reliable for most folks but Berger riders and/or rippers will kill them. Bottom tier is stuff like e13 and Stan’s Neo hubs-junk all day.

So…..i9 is okay, but charges as much or more than much better options. And if you want pretty colors, Hopes are a better buy. Or get some SLX or XT hubs for waaaaaay less money and deal with bearing service once in a while.

 @wyorider: I wonder how often Yoann Barelli goes through i9 hubs. No doubt he breaks things, and I’m sure he’d eventually break anything given the riding he does. Beyond the money and the fact that he’d get unlimited amounts of anything he breaks, he’s trusting his life to these things to some extent — riding some really gnarly stuff:
