Industry Nine Triad Aluminum SYSTEM Wheelset
The Industry Nine Triad Aluminum System wheelset is the enduro version of Industry Nine's flagship System build on an aluminum rim: a 30mm internal Hollow Bead alloy rim laced 32 spokes front and rear with machined aluminum System spokes to the Hydra2 System hub. Industry Nine lists it at 1909 grams for the pair, 873 front and 1036 rear, in 27.5in or 29in.
System means the hub shell and the spokes are machined in Asheville, North Carolina, the spokes thread straight into the flange, and both come in seven anodized colors. On the Triad Aluminum it gives you the Hydra2's 870-point drive and the full color treatment on a rim that costs less than carbon and dents rather than cracks.
The Triad Aluminum System is for the enduro or aggressive trail rider on a 150 to 170mm bike who wants Industry Nine's best hub and the colored spokes, and prefers an aluminum rim, whether for budget, feel, or peace of mind in rocky terrain.
Design and construction
The rim is the Triad Hollow Bead aluminum: 21.3mm deep, 30mm inner width, tubeless ready, drilled 32-hole front and rear. The hollow bead wall is Industry Nine's design for better pinch-flat resistance and impact strength than a solid bead on an alloy rim. The aluminum rim carries a two-year warranty against defects and is not covered for impact or crash damage.
The hub is the Hydra2 System, with 870 points of engagement, 0.41 degrees between clicks, six three-tooth pawls, about 60 percent less coasting drag than the original Hydra, a much thicker axle, and a five-year limited hub warranty. The straight-pull flanges are drilled for Industry Nine's one-piece 7075 aluminum System spokes, and the hub is 6-bolt.
Colors on the Triad Aluminum System are chosen for hubs and spokes separately: Black, Bronze, Gold, Orange, Purple, Red, and Silver.
Triad is shaped, tested and tuned for enduro, and the second-generation laminate increases impact strength while changing how the wheel reacts underneath you - the two are not the same thing, and tuning for both is the harder problem.
Industry Nine's aluminum System spokes
Every Triad Aluminum wheel is built on Industry Nine's aluminum System spoke, and it is the reason a System build rides and looks the way it does. Each spoke is machined from a solid bar of 7075-T651 aluminum in Industry Nine's own facility in Asheville, North Carolina, as a single straight-pull piece: it threads directly into the Hydra2 System hubshell at one end and carries integrated wrench flats at the rim end, so there is no J-bend and no separate nipple anywhere in the wheel. Those two features are where a conventional steel spoke usually fails, at the work-hardened bend and at the threaded nipple interface, and the System spoke simply does not have them. The Triad Aluminum is laced 32-hole.
On the Industry Nine Triad Aluminum System wheelset the aluminum spoke is not a lightweight compromise. Industry Nine gives it a 25 to 30 percent larger cross-sectional area than a comparable steel spoke, which it rates as equal in tensile strength to a 14/15-gauge double-butted steel spoke, and the thread root diameter is larger than the spoke body, so the spoke is strongest exactly where a steel spoke is thinnest. The result is a stiff, direct-feeling wheel that holds tension and tracks precisely. Industry Nine builds System wheels to a target tension of 120 kgf and holds every spoke within 10 percent of that figure.
Because the spokes are anodized rather than painted, they come in the same seven colors as the hubs, and the hub and spoke colors are chosen independently, so a bronze hub with silver spokes or an orange hub with black spokes is a normal order rather than a custom one. The Hub Color and Spoke Color menus on this Industry Nine Triad Aluminum System page drive exactly that choice and the preview picture follows it. One thing to know before you order: Industry Nine keeps the System spoke in-house and does not sell it over the counter, so a System wheel is serviced and rebuilt through authorized dealers such as ProWheelBuilder, and the spokes are warranted against manufacturing defects. If you would rather have a wheel any shop can re-spoke with stock parts, Industry Nine's Classic and 1/1 builds use the same rims with steel J-bend Sapim spokes and conventional nipples.
How it rides
The Triad Aluminum System is a stiff, responsive enduro wheel. Thirty-two aluminum spokes a side make it track accurately and hold tension through hard riding, and the Hydra2 drive is on the power the instant you pedal. The 30mm bed supports 2.4 to 2.6in tires at the lower pressures enduro riders run.
Against the carbon Triad it gives up a little weight and a little precision, and it will take a flat spot from a bottom-out that the carbon rim would ignore. In exchange, a dented aluminum rim usually finishes the ride and can often be straightened. For riders who race in rocky places or who simply prefer alloy, the Triad Aluminum System is the full Industry Nine experience on a rim you do not have to worry about.
The 32-hole front is worth mentioning. The carbon Triad runs 28 spokes up front; the aluminum version runs 32 at both ends, which along with the aluminum System spokes makes this one of the stiffest front wheels Industry Nine builds for a trail or enduro bike. Heavier riders and riders who push hard into berms tend to appreciate that.

Testing, standards and warranty at Industry Nine
Industry Nine has anodized and machined hubs, spokes, and drive systems in Asheville, North Carolina since 2004. The company grew out of a family machine shop in the Blue Ridge and states that it engineers and manufactures every component of its hub and wheel systems in-house, including hub shells, axles, spokes, pawls, drive rings, and anodizing. Complete wheels are hand built to order and ship in approximately two weeks, fulfilled from Asheville, Kamloops, or Cadiz depending on location and inventory. In 2025 Industry Nine acquired We Are One Composites, which now operates as WR1, its carbon rim design program and manufacturer; WR1 has hand laid carbon rims under one roof in Kamloops, British Columbia since 2017.
Three hub platforms cover the range. Hydra2, the flagship mountain hub, was developed from feedback on more than 100,000 first-generation Hydra hubs and pairs a reinforced 145-tooth steel drive ring with six phased oversized pawl pockets for 870 points of engagement at 0.41 degrees. Industry Nine cites a 65 percent thicker axle, 5.5mm pawl pockets with 26 percent better force dissipation, 60 percent less coasting drag than the original Hydra, 6903 hub shell bearings, and full-contact radial lip seals with a labyrinth channel; it is rated for trail, enduro, downhill, e-bike, bikepacking, and dirt jump use. Solix, the gravel, road, and cross-country hub, uses a patented continuously phased freehub in which five pawls and a 121-tooth drive ring produce 605 points of engagement at 0.59 degrees. Its pawls and drive rings are cut from A2 tool steel by wire EDM, bearing spec is equalized front and rear, end caps carry full-contact seals behind a proximity dust and water shield, and preload is set by bore-diameter contraction. The 1/1 hub is the entry platform, with a dual-phase pawl drive giving 90 points of engagement at 4 degrees, high-capacity bearings, and a conventional flanged shell for J-bend Sapim steel spokes. Hydra2 and Solix are offered as System hubs, which take Industry Nine's direct-thread machined aluminum spokes, or as Classic hubs with scalloped flanges for J-bend steel spokes.
Convergence is the carbon rim technology shared by the Whisp, Sector, Triad, Deal, Fuse, Wanderer, and Revive 2.0 rims. Industry Nine says the program ran through 208 versions over two years before release. The rim's alternating spoke bed faces are angled at 7.5 degrees so that each nipple bed aligns with the hub flange, producing a linear spoke line and 360 degree contact between nipple and rim; articulation is listed as plus or minus 7.5 degrees for mountain rims and plus or minus 6 degrees for gravel and bikepacking rims, with a 4.3mm spoke hole. A ZRT composite film from Boston Materials, containing 13 billion Z-axis carbon fibers per square meter, is built into the spoke bed, and Industry Nine reports the rim is 32 percent stronger than its predecessor with tuned vertical compliance. Every Convergence rim is laid up by a named technician, assigned a serial number, and shipped without sanding, filling, or painting. On the road side, the R35, R50, and R65 carbon rims are described as CFD born and wind tunnel tested and among the fastest disc-specific rims available. Industry Nine characterizes its validation as in-house pressure testing in the same environments its riders use rather than published laboratory figures, and it does not list a rider weight limit on current product pages.
Warranty coverage is administered from Asheville for the United States and Canada. All Hydra2 and Solix hubs carry a Five-Year Limited Hub Warranty regardless of purchase date; for other products the current terms apply to purchases made on or after January 1, 2026. Hubs are covered against defects in materials and workmanship for five years, with parts, labor, and return shipping included in the first two years and parts only in years three through five; bearings and other wear items are excluded. Carbon rims are covered for the life of the original owner against defects and also against impact damage sustained while riding within the wheel's intended use, with a rim replacement or a factory rebuild offered when a claim qualifies. Alloy rims are covered for life against manufacturing defects, including split seams and cracks at spoke holes, with full parts, labor, and return shipping for the first two years; impact or crash damage on alloy rims is not a warranty item but may qualify for the Crash Replacement program. Aluminum System spokes are covered for confirmed manufacturing defects. Coverage applies to the original purchaser with proof of purchase from a certified Industry Nine dealer or distributor, and claims are filed through the Service and Warranty Request form on the company's website. Industry Nine also offers factory service on all products and states that no proprietary tools are required for routine hub service.

Triad Aluminum SYSTEM on video
A note on Industry Nine
Industry Nine makes in North America, in Asheville, North Carolina, and makes an unusual amount of the wheel itself. The hubs, the spokes and the rims come from the same company with the same tolerances, which is the argument for buying the wheel as a system rather than assembling one from three suppliers.
Ordering it from ProWheelBuilder
ProWheelBuilder sells the Triad Aluminum System wheelset as an authorized Industry Nine dealer in Georgia. Industry Nine builds it to order in Asheville, North Carolina and ships in about two weeks. We are not the manufacturer; we verify your axle, driver, and brake selections against the actual bike so the wheel bolts on when it arrives.
If you want a Hydra2 System hub on a different aluminum rim, or a steel-spoke enduro build we can service in-house, our Custom Wheel program builds on Industry Nine hubs to your spec.
Warranty
Industry Nine's warranty. Industry Nine covers its hubs against defects in materials and workmanship for five years from purchase, with two years on the anodized finish. Its alloy and carbon rims carry a lifetime defect warranty to the original purchaser, with parts, labor and return shipping covered for the first two years and parts thereafter. Bearing wear, impact and crash damage are not defects.
ProWheelBuilder. These wheels were built at the factory, not on our bench, so it is the maker's warranty above that stands behind them - our own one-year wheel warranty covers wheels we lace ourselves. If you do need to claim, we will deal with the manufacturer for you.
