Industry Nine All Mountain – First Look

by Brian Mullin on November 8, 2010

I just got in a fresh set of the Industry Nine All Mountain wheels to test, and I was pretty stocked up to try them out. I had always respected the build quality of their wheels, and the highly engineered innovative hubs, but I was craving to try out the 120 point of engagement freehub. All the I9 wheels use their straight pull hubs, and aluminum spokes, which makes them pretty unique system. Everything except rims and bearings are made in their Asheville, NC site.

The freehub uses two sets of three pawls (second one phased three degrees from first), which are made from A2 tool steel, and each has three points, for 9 points of contact per set into a A2 hardened 60 tooth ring, giving 3 degree engagement (120 point, 3 degree engagement, 6 pawl mechanism). The I9 All Mountain come with a 26mm wide and 32 hole All Mountain rims, and their Enduro hubs, and .100 inch aluminum spokes. The hubs can be spec’ed in almost any size (adapters are available to convert the hubs) or color, 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 9, 15, 20, 24, or 25mm, and the rear to be 9, 10 or 12mm.

The I9 spokes are CNC machined from 7075-T651 aluminum, and have a larger cross section than comparable steel spokes, but weigh less and have a higher 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. Nipple less! The I9 hub shell body is CNC machined from 7075-T651, while the freehub uses 7068 alloy for durability, and they turn on one piece aluminum axles and ABEC grade 5 bearings.

They are very light, coming in at 1663 grams for the test pair, which are 20mm front and 12x135mm rear.

 
Impressions
I have been pummeling them pretty hard on some local terrain, including lots of rock gardens, rocky ledges and plenty of abuse. The front wheel is one stout beast, and I couldn’t feel any sort of flex coming from them, though they still had a lively feel and would turn on a dime. You could toss them into a corner or berm, with hardly a whimper from them. The rear hub is simply amazing, and I am highly impressed with the high point of engagement. In difficult technical terrain, you could just crank on the pedals, and the hubs would react instantaneously, as there was no lag whatsoever. I could apply power almost anywhere I wanted, at any angle, direction, and terrain obstacle. They also allowed you to track stand, catch your balance (and composure), and start up again, almost like you were on a Fixie (ok, just sort of!). They were pretty quiet, and only gave a muted whirl noise, buzzing up to a whiz sound at higher speeds, but not very noticeable when hammering down the trail.

Conclusion
The I9 AM wheels are pretty darn sweet! 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, with virtually no lag in the power transition, making pedaling a joy, especially in highly technical terrain. I am looking forward to more testing and riding.

Gram – were you able to set the I9 AM up tubeless using just the Stan's Yellow Tape or do you need Rim Strips (assume the later)?

Thanks,
Shane

Shane,
I used rim strips, though I think a few layers of Stan's tape would have done the trick. I used some generic brand for one layer, but ran out of it and wasn't able to try more layers. I think I would build these with Stans Flow rims

I have a set of I9 AM's and Stans tape did the trick without a problem. I'm now running Rubber Queens (UST) tubeless.

On the review at the end it has the WEIGHT : 1750 grams. I9 web site claims 1650 grams and at one point in your review it has the Front – 747.1 grams
Rear – 915.5 grams
Total – 1662.6 grams. Hopefully this is a typo because if I can get these wheels with a lefty front at 1662 grams I am ordering soon but at 1750 I'm exploring other options.

Yeti Ben – the 1750 was their last claimed weight when I retrieved info from their site, the set I had weighed in at 1663 grams. I see it now shows 1650, so they must have had a typo?
