Industry Nine All Mountain Review

Pro Reviews Wheels


The Industry Nine All Mountain wheels are pretty darn sweet, as they are lightweight, brutally strong, look good, are well made, and have one of the most amazing freehubs I have ever used! Instant power can be applied to the wheel due to their 120 point of engagement hub, with virtually no lag in the power transition, making pedaling a joy, especially in highly technical terrain. All the I9 wheels use their straight pull hubs, and aluminum spokes, which makes them a pretty unique system. Industry Nine is a small Asheville, NC company, and they do onsite design, manufacturing, quality control, sales, assembly, truing and tensioning of their products (the rims and bearings are outsourced).



Industry Nine All Mountain
The I9 All Mountain’s comes with their 26mm wide and 32 hole All Mountain rims, and their Enduro hubs, and .100 inch aluminum spokes. The straight pull hubs can be spec’ed in almost any size (adapters are available to convert the hubs), and the hubs and spokes are available in 11 colors (Red, Black, Silver, Blue, Brown, Gold, Green, Orange, Pewter, Pink, or Purple), while the rims are either black or white. I9 has a great selection of adapters for their hubs, and the replaceable end caps, allow the front to be a QR, or 9mm, 15mm, 20mm, 24mm, 25mm thru axles, and the rear to be a QR 135, or 10x135mm, 12x135mm, 12x142mm thru axles. They come with a three-year warranty against defects in materials or craftsmanship. There are some additional custom options, such as Singlespeed, Lefty, Ceramic bearings, and they can be built to any 32 hole rim. Recently, I9 began to offer the Classic hub, which offers all the great benefits of their hubs, without the proprietary spoke system.


The unique I9 spokes are CNC machined from 7075-T651 aluminum, and have a larger cross section (20-25%) than comparable steel spokes, but weigh less, have a greater lateral stiffness and equivalent tensile strength. The rim end of the spoke is just a flared flange, and it floats in the rim hole, while the other end threads directly into the straight pull hub, and the thread section (very coarse) is larger than the spoke diameter. They are fatty, and nipple less! The one piece design of the spoke means they perform like an extremely long screw (insert rude joke). Since there spoke and hub is made from the same material, there isn’t any corrosion nor galling issues, that can occur when unlike metals interact. The spokes are laced up in a three-cross pattern, though they appear to be two crosses, they actually make another pass over each other when they are threaded into the hub.

Brian likes to push the limits in all the sports he obsesses in, whether it's mountain biking, whitewater kayaking, skiing, or sport climbing. He takes those same strengths and a good dose of insanity to his reviewing and writing on mountain biking products, creating technical, in-depth articles. Whenever he's not on the bike, he might be found watching MotoGP racing, otherwise look for him out on the trail.

    One correction: Galling can happen to parts made of the same material. In this case the anodizing prevents it, not the material selection. Good review though!

  • Brian Mullin says:

    cojacket: You are correct, and thanks for info, and the article has been corrected. If it was hard anodized they will not gall, but it could be more of a regular decorative anodizing, and then durability would be an issue, but the spokes are not really going to be adjusted much? Not sure?

  • jen says:

    the machining in the first picture looks shit!

  • Kevin Kaehms says:

    I’ve had to constantly re-tighten my I9 spokes after every ride; yes they’re light, strong and have incredible engagement- but the spokes are continually coming loose.

  • Brian Mullin says:

    Kevin: My spokes have been fine, and have only needed minor tweaking. The wheels have stayed in true better than most?

  • Brad Fitkin says:

    I bought my I9 AM wheelset about 8 months ago, even though I read quite a few claims about I9 wheels that spokes constantly loosen, they break easily, the freewheel has too much drag, etc. I’ve given ’em hell, and they’ve chewed it up and spit it out. I’ve had to tighten one spoke, haven’t broken one yet (got a few dings and a slightly bent one due to rocks, etc), and the initial drag on the freewheel has quickly become a total non-issue after break-in. Despite a single loose spoke and a slightly bent one, my wheels remain true. My goal was to upgrade my wheelset to top-shelf, install it and forget about it status, and these wheels have exceeded my expectations.

  • Kevin Kaehms says:

    Brian, what kind of wheel build do you have,(XC, all mountain, DH, etc…)? My I-9 build is a DH wheelset and I’m 200+lbs so I tend to be hard on equipment. Still no complaints with the hubs, but if I were to do it over again I’d probably go with their “classic” hubs & standard spokes- may be a heavier build, but because of my weight I tend to prefer durability over total bike weight.

  • TOU93 says:

    I’ve had I9 AM on my bike for just over a year now and they have been awesome! Mine are laced up with Stans ZTR Flow rims and have handled many days at DH parks. I’ve only had to true them once. If you read the instructions that come with them it says to get them re-tentioned after 4-6h of first riding them to make sure everything is fine.

  • Brian Mullin says:

    Kevin: AM setup, I am tough on wheels cause I do real low speed technical trials stuff, jamming a lot of torque onto the system, but I only weigh in at 155 lbs.

  • Jeff says:

    @ Kevin: The most common cause of chronic de-tensioning is overall low spoke tension. Have your bike shop tension the wheels and verify the tension with a Park or DT Swiss tensiometer. The conversion #’s are on Industry Nine’s website. If the wheels are properly tensioned, de-tensioning shouldn’t be an issue.

  • mc says:

    Great review! These are so much stiffer than my Hadley/Flow combo I was running. Engagement is about the same, but lateral stiffness if noticeable. Got them running tubeless with just two passes of Stans Yellow tape and WTB TCS tires. No issues so far and holds air just like my Stans did. Worth the extra money.

  • Brad says:

    I have a set of the I9 proprietary enduro hubs. They are tough as hell , with very little truing at all. However; I am consisently having a problem with the rear axle coming loose, which results in a very loud creaking noise. Anyone else have this issue going on?
