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.
