Industry Nine Fuse Carbon SYSTEM Wheelset
The Industry Nine Fuse Carbon System wheelset is Industry Nine's e-bike wheel built the flagship way: a 33mm internal Convergence carbon rim designed for motor torque and added system weight, laced with machined aluminum System spokes to the Hydra2 System hub. Industry Nine lists it at 1938 grams for the pair, 897 front and 1041 rear, in 27.5in or 29in.
System is the platform where the hub shells and spokes are machined in Asheville, North Carolina, the spokes thread straight into the flange, and each comes in seven anodized colors. On an e-bike wheel that combination is particularly well matched: a motor multiplies every pedal stroke, so a stiff spoke system and a hub with 870 points of engagement turn that torque into forward motion with no lag.
The Fuse Carbon System is for the full-power e-MTB rider on a 150 to 170mm bike who rides aggressively and wants a wheel designed for the loads an e-bike creates rather than a trail wheel asked to cope.
Design and construction
The Fuse rim is a Convergence carbon e-bike profile: 33mm inner width, 18mm deep in 29in and 21mm deep in 27.5in, hookless, tubeless ready, drilled 28-hole front and 32-hole rear. The wide bed supports the 2.5 to 2.6in tires e-bikes run, and the layup is built for sustained torque and repeated load. We Are One hand lays the rims in Kamloops, British Columbia; the shaped nipple bed keeps each spoke square to the rim wall. Industry Nine covers the carbon rim for life, riding impact damage included.
The hub is the Hydra2 System: 870 points of engagement, 0.41 degrees between clicks, six three-tooth pawls, about 60 percent less coasting drag than the original Hydra, and an axle around 65 percent thicker, which on an e-bike is the upgrade you want. It comes with a five-year limited hub warranty and is drilled for Industry Nine's one-piece 7075 aluminum System spokes. The hub is 6-bolt.
Hub and spoke colors are chosen separately from Black, Bronze, Gold, Orange, Purple, Red, and Silver.
Industry Nine's aluminum System spokes
Every Fuse 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 Fuse Carbon is laced 28-hole and 32-hole.
On the Industry Nine Fuse 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 Fuse 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
On an e-MTB the Fuse Carbon System feels immediate. The Hydra2's near-instant engagement pairs well with a motor that is always ready to add torque, and the aluminum spokes and 33mm carbon rim make a stiff wheel that does not squirm under the extra mass when you lean the bike into a berm. The wide rim keeps a 2.6in tire from folding at the lower pressures heavy bikes want.
It is a stiff wheel, which is appropriate on a 50-pound bike but worth knowing if you like a soft feel. The rear rim in particular is built to shrug off the square-edge hits an e-bike carries speed into. Riders who have bent or cracked trail wheels on an e-bike will notice the difference in the first ride, and the lifetime impact warranty on the rim means the next rock strike is not a financial event.

About this Fuse Carbon SYSTEM Wheelset listing. The choices on this page are driver type: Shimano HG, Shimano Micro Spline, SRAM XD; axle: Wheelset - 15x110mm F / 12x148mm R, Wheelset - 15x110mm F / 12x157mm R, Wheelset - 15x110mm (20mm hub) F / 12x148mm R, Wheelset - 15x110mm (20mm hub) F / 12x157mm R, Wheelset - 15x110mm RockShox Torque Cap F / 12x148mm R, Wheelset - 15x110mm RockShox Torque Cap F / 12x157mm R, Wheelset - 20x110mm Boost F / 12x148mm R, Wheelset - 20x110mm Boost F / 12x157mm R; hub color: Black, Bronze, Gold, Orange, Purple, Red, Silver; i9 alloy system spoke color: Black, Bronze, Gold, Orange, Purple, Red, Silver; wheel(s): Wheelset - 29", Wheelset - 27.5", Wheelset - Mullet (29" F / 27.5" R). This listing is the complete wheelset - front and rear together, not a single wheel.
Fit and compatibility
The Fuse Carbon System comes in 27.5in and 29in. Front spacing is 15x110 Boost, 15x110 on a 20mm hub shell, 15x110 with RockShox Torque Caps, or 20x110 Boost; rear spacing is 12x148 Boost or 12x157 Super Boost.
Freehub bodies are Shimano HG, Shimano Micro Spline, and SRAM XD; a front wheel ordered alone takes the None (front wheel only) driver choice. The System hub is 6-bolt; the Fuse Carbon Classic and 1/1 offer Centerlock. E-bike frames use a range of rear spacings and some motors dictate the driver, so we confirm both before Industry Nine builds the wheel.
Industry Nine's testing and certifications
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
A good deal of the range is developed under World Cup racing and then revised for everything that happens after the race tape comes down: park laps, blown-out turns and shuttle days. The parts that survive that are the ones that reach the catalog.
Ordering it from ProWheelBuilder
ProWheelBuilder sells the Fuse Carbon System wheelset as an authorized Industry Nine dealer in Georgia. Industry Nine builds each set to your colors and standards in Asheville, North Carolina and ships in roughly two weeks. We are not the manufacturer; we take the order, check the axle and driver picks against your e-bike's frame, fork, and drivetrain, and support the wheel afterward.
If you want a Hydra2 System hub on a different e-bike rim, or a J-bend build we can service in-house, our Custom Wheel program builds custom wheels on Industry Nine hubs in our shop.
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. This is a complete wheelset built by its manufacturer rather than in our shop, so the maker's warranty above is the one that applies to it. ProWheelBuilder's own one-year wheel warranty covers the wheels we build. We will still handle a manufacturer claim on your behalf.
Full terms are on our Policies & Warranty page.
Fuse Carbon SYSTEM questions
Is ProWheelBuilder the manufacturer of the Fuse Carbon System?
No. Industry Nine builds it in Asheville, North Carolina, using Convergence carbon rims made by We Are One in Kamloops. ProWheelBuilder is a reseller and custom wheel builder in Georgia.
What makes the Fuse an e-bike wheel rather than a trail wheel?
A 33mm inner width for wide tires and a rim layup Industry Nine designed for sustained motor torque, added system weight, and repeated load. The Hydra2's thicker axle helps too.
Is the System hub Centerlock?
No, it is 6-bolt. Centerlock is offered on the Fuse Carbon Classic and 1/1.
What tire width suits the 33mm rim?
2.5 to 2.6in e-MTB tires.
Does it fit a 20mm front axle?
Yes. 20x110 Boost is offered, plus 15x110 on a 20mm shell.
What is the warranty?
Lifetime on the carbon rim including riding impact damage, and a five-year limited hub warranty on the Hydra2.
