Hey Pinkbike community!

I've been having some problems with a new set of 29" alu Industry Nine Enduro S wheels and wanted to see if anyone's had similar issues and canvas you all for opinions...

First things first, I'm 82 kg (180 lbs) and run 27/25 PSI on the back/front with double down tires.

I bought the wheels in October but only started using them properly in March this year, so they're pretty new. Since then, I've had multiple spokes rattle loose on the back wheel (so much that I've needed to completely re-true it each time) - this has happened three or four times so far this season. Coupled with that, I've now got six (!) impact dents in the rim - even though the kind of trails I ride is aligned with the intended use of the wheels and I haven't had any big knocks on the back rim. I've spoken to I9, who have told me that they don't cover rim impacts on warranty, so this is on me.

So here are my questions...

1. Anyone else had similar issues?

2. I don't think it's right that multiple spokes have rattled loose multiple times in only a few months of use (never happened to me before). Is that fair?

3. Since I haven't had any big knocks on the rim (the wave of panic is pretty memorable!), is it possible (likely?) that the rim dents happened because the spokes came loose and warped the wheel mid-ride?

4. Do you think I9's stance to refuse the warranty is fair?

How much do you weigh and how much PSI are you running?

Thanks for the question! Now edited the post to include weight (82 kg / 180 lbs), psi (27/25) and tires (double down).

I ran enduro S hydra wheels for the past 3 seasons. Spokes would come loose all the time, and I had to replace my rear 3 times during that timeframe, luckily my friend is an I9 dealer so he managed to get it replaced/serviced as a warranty job after it cracked at the spoke. Had to just pay for a rim the other times which wasn't too bad but pretty annoying. Was running double down with tannus inserts, 180lbs at 26/24 psi

I came to the conclusion that these wheels are better suited to aggressive trail rather than hard enduro or freeriding, especially with the 28 hole set up (which I'm assuming you have too?). I saved up for a pair of carbon Nobl Tr37s w Hydra hubs this year and haven't looked back.

Thanks @vermontana! Yep 28 spokes - guess I'll have to get my teeth stuck into it and just keep retuning until I can buy my way out of it. Thanks for the tip on the Nobl tr37s - hadn't heard of them until now but they look sick!

They suck. My 125lbs kid is running 28psi in the rear and the first rear lasted a week or so before it had to be trued. In their defense; he did ding the sidewall of the rim but it holds air fine. Went to Whistler two weeks later and had to true it again after 3 days there, so of course, all bets are off at that point. It lasted 2 more days and cracked half way thru the last day there. I9 sent a replacement; spent $150 to get it rebuilt and got two days out of the second one (with a Cush Core added). He does send some big air, but still?? I’m 180lbs and have never gone thru a wheel that fast. He Loves the Hydra hubs! The rims should be called Bike Path S. He has a race in 4 days and now have I to scramble to find a DT Swiss EX 511 and get it built up.

Wow, so it's not only my issue. I'm heavy, 240lbs, ride quite aggressively and I need to retrue wheel pretty much every few rides. They came with my new bike and honestly I didn't think I would this issue buying them in a super boost spacing rear hub. Nope, constant problems with this wheel. I don't have any rim dents, I'm running 26-28psi on the rear with tannus insert. I had one radial bump with a few close to loose spokes. In fact I'm so annoyed by that wheel I'm collecting all parts to build a new wheel with dt 240 hub + fr 541. Maybe i9 is too compliant, which was stated by a shop btw, because in super boost spacing spokes are not touching each other reducing lateral stiffness. Sketchy explanation.

Funny thing is that on my previous bike I had very basic DT Swiss M1900 Spline (current price is ~350€ for a set) and I never had to retrue a wheel, no dents, no radial wobble. That's why I'm going back to DT and i9 will be a spare wheel. :/

Is it possible to run another brand rim with the Hydra hubs? Maybe DT Swiss or Stans?

I know this is an older but I had the same problems with my set of i9 trail s around the end of 2021. After replacing a few spokes, I called i9 up and they warrantied the wheel no questions asked. They had some sort of issue with manufacturing or something, I don’t recall exactly anymore.

Surely the answer here is just to dich the rims and replace with DT Swiss EX511 rims. I think you can even use the same Sapim spokes (according to the DT wheel calculator) so it's just two rims and some new nipples.

I have a set of i9 Hydra wheels turning up this week as OE fit on my new Evil Insurgent MX. I am taking it out to Madeira next week for a full winter of enduro/downhill fun and games.

I have a Canyon Strive out there which came with DT Swiss E1900 wheels from stock. I killed the rear rim so ordered up new EX511's and new nipples and had the wheels rebuilt. They have been utterly faultless and run true after almost 2 seasons of heavy abuse (I'm circa 220lbs fully laden). I will give the i9 rims a go and then replace as soon they start giving hassle.

Annoyingly the new bike is mullet so I can't even nick the rims from the Strive.

Well quick update on this. i9 Enduro S wheels officially suck balls and are simply not fit for purpose unless accompanied by a 'no riders over 25kgs and no off-road use' caveat.

Three rides, three broken spokes.

Utterly crazy. I have never broken a spoke before and I am riding the same trails as usual at the same pace.

Whoever thinks 28 spokes is sufficient for an Enduro wheelset needs their head looked at. There also seems to be a weak point where the spoke leaves the nipple as the spoke is pulled away at an angle.

My plan now is to junk the Sapim spokes and replace with some much thicker and stronger DT Swiss spokes. If that doesn't work, I'm going to through the wheels off a cliff and build a set of EX511 on Hope Pro 5's.

Really REALLY pissed off. There ruined rides in Madeira mountains.

I do not recommend. I've been on the Enduro S and have gone through two wheels (rear with cushcore and double down casing). I agree with sentiment above that they are a better trail wheel than Enduro / aggressive riding. Love the hub but wheels are not durable for aggressive hard riding on rocky terrain. 6'4, 200lb in the Rockies..29", 25/29 PSI.

I have 27.5s on my Warden and 29s on my Tyaughton. The set on the Warden has been holding up nicely, but the Tyaughton rear started giving lots of pinging with lateral movement (you can make the sound just by flexing the wheel a little while even unweighted or just pedaling the trail). The wheels are all still true.

I do not run inserts. I ride nearly everything at Galbraith and North Shore except for the big drops and pro-lines. I'm around 220 fully loaded and run around 23psi in the front and 27 in the rear. Never got any dings in the rims on the 27.5s (two years running now) or the 29s (around a dozen rides). So... as far as I've seen, the rims are holding up, but possibly someone did a bad job lacing the 29s up.
