Industry Nine Sector Carbon SYSTEM Wheelset
The Industry Nine Sector Carbon System wheelset is the trail wheel Industry Nine builds when nothing is held back: a 29mm internal Convergence carbon rim, the Hydra2 System hub, and Industry Nine's machined aluminum straight-pull System spokes in the color of your choice. Industry Nine lists the pair at 1605 grams, 714 front and 891 rear.
System is Industry Nine's flagship platform. Instead of a J-bend hub and steel spokes, the hub shell is machined with straight-pull flanges and the spokes are one-piece 7075 aluminum, threaded at the hub end and machined in Asheville, North Carolina alongside the hubs. The result is a lighter, stiffer wheel than the equivalent steel build, and one you can order in any of seven anodized colors for the hubs and seven for the spokes.
The Sector Carbon System is for the trail rider on a 120 to 150mm 29er who wants the fastest-engaging hub on the market, a rim that carries a lifetime impact warranty, and a wheel that looks like it was built for them specifically, because it was.
Design and construction
The Sector rim is a Convergence carbon trail profile: 21mm deep, 29mm inner width, hookless bead, tubeless ready, drilled 28-hole front and 32-hole rear. We Are One Composites hand lays these rims in Kamloops, British Columbia, and their nipple bed is shaped so every spoke enters the rim square to the wall, which spreads load evenly and is a big part of why Convergence rims hold tension so well. Industry Nine covers the rim for life, riding impact damage included.
The hub is the Hydra2 System. Its drive uses six three-tooth pawls to reach 870 points of engagement, or 0.41 degrees between clicks, while cutting coasting drag roughly 60 percent compared with the original Hydra; the axle is also about 65 percent thicker than before. It carries a five-year limited hub warranty. The System hub is 6-bolt; if you run Centerlock rotors, the Sector Carbon Classic offers that mount.
Colors on the Sector Carbon System come in two separate picks, hub and spoke: Black, Bronze, Gold, Orange, Purple, Red, and Silver for each. Matching or contrasting both is up to you.
Sector is built for the all-day ride: a re-engineered Convergence layup that stays composed through rough descents while staying light enough to climb with deep in the backcountry.
Industry Nine's aluminum System spokes
Every Sector Carbon 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 Sector Carbon is laced 28-hole and 32-hole.
On the Industry Nine Sector Carbon 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 Sector Carbon 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 Sector Carbon System is a precise, quick trail wheel. The aluminum spokes and carbon rim build a stiff structure that holds its line under hard cornering and does not wander when you load the front end into a berm, and the Hydra2's 0.41 degree pickup makes ratcheting through rocks on a technical climb feel almost continuous. The 29mm bed suits 2.3 to 2.5in tires and lets you run them at trail pressures without squirm.
It is a stiff wheel, and riders who prefer a softer, more damped feel sometimes find the System spokes a little direct on chattery, hardpack descents. That is the trade for the weight and the response. For a rider who climbs and descends with equal intent on a modern 29er trail bike, and who wants the wheel to reward pedaling as much as it tolerates abuse, it is hard to argue with.

How Industry Nine tests its wheels
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.

A note on Industry Nine
Convergence is the name Industry Nine gives its carbon rim platform, and the models are not one rim in different widths: each gets its own layup, tuned for what that wheel is asked to do. It is why a Sector and a Triad can share a factory and a philosophy and still ride nothing like each other.
Ordering it from ProWheelBuilder
Ordering the Sector Carbon System wheelset through ProWheelBuilder means Industry Nine builds it to your colors and standards in Asheville, North Carolina, and ships it in roughly two weeks. We are a custom wheel builder in Georgia and an authorized Industry Nine dealer; we do not manufacture the wheel, but we check every axle and driver selection against your frame, fork, and cassette so nothing comes back for exchange.
If you want a Hydra2 hub on a different rim, a 32-hole front, or a J-bend build you can service anywhere, our Custom Wheel program lets you spec Industry Nine hubs into a wheel we build here.
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. Because this wheelset comes assembled from its maker, the warranty that applies is theirs, set out above; ProWheelBuilder's one-year wheel warranty is for wheels we build here. Either way, a claim goes through us and we will manage it.
