Industry Nine Whisp Carbon SYSTEM Wheelset
The Industry Nine Whisp Carbon System wheelset is the top of the Whisp line: a 29mm inner width Convergence carbon cross country rim laced with Industry Nine's own straight-pull aluminum System spokes to the Solix System hub. Industry Nine lists it at 1368 grams for the pair, 630 front and 738 rear, which puts it in genuine race-wheel territory without going to a narrow rim.
The System platform is what most people picture when they think of Industry Nine. The hub shell and the spokes are machined in Asheville, North Carolina, the spokes thread directly into the hub flange rather than bending through it, and both hub and spokes come in seven anodized colors that you mix however you like. On the Whisp Carbon System that means a wheel that is lighter and stiffer than the J-bend versions and looks unlike anything else on the start line.
This is the version for the rider who races cross country, rides marathon events, or simply wants the fastest 29er wheel Industry Nine builds, and who is happy to accept a proprietary spoke in exchange for the weight and the finish. It also fits a wide gravel bike, since the rim is offered in both 29in and 700c labeling and the hub takes 12x100 and 12x142 axles.
Design and construction
The rim is the Convergence carbon Whisp: 21mm deep, 29mm internal, 28-hole front and rear, hookless and tubeless ready. Convergence rims are hand laid by We Are One Composites in Kamloops, British Columbia, and use a shaped spoke bed that lets each nipple seat square to the rim wall, which is a large part of why they hold tension so evenly. Industry Nine covers the carbon rim with a lifetime warranty that includes riding impact damage.
The hub is the Solix System, Industry Nine's lightest platform, built for XC, gravel, and road. Its drive uses five phased pawls on a 121-tooth drivering for 605 points of engagement, or 0.59 degrees between clicks, and it carries a five-year limited hub warranty. The System version of the hub has tall flanges drilled for straight-pull spokes; those spokes are one-piece machined 7075 aluminum from Industry Nine's Asheville shop, and they are what shave the weight off compared with the Sapim steel builds of the same rim.
The Whisp Carbon System is ordered by hub color and spoke color, seven choices each: Black, Bronze, Gold, Orange, Purple, Red, and Silver. Brake mount is not a selectable option on this build, so if you run Centerlock rotors tell us before we place the order and we will confirm the interface with Industry Nine.
Industry Nine's aluminum System spokes
Every Whisp 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 SOLiX 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 Whisp Carbon is laced 28-hole.
On the Industry Nine Whisp 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 Whisp 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 singletrack the Whisp Carbon System feels quick in the way a good XC race wheel should: it spins up fast, the aluminum spokes and carbon rim make for a stiff wheel that tracks precisely through rooty corners, and the 605-point Solix drive means there is essentially no dead stroke when you get back on the pedals out of a switchback. The 29mm bed gives a 2.25 to 2.4in tire a squarer, more supported profile than the 25mm rims most race wheels still use, so you can run lower pressures without the tire folding.
The honest trade is that stiff, light wheels transmit more trail chatter than heavier trail wheels, and a 28-spoke XC build is not what we would put under a 220-pound rider who likes to plow through rock gardens. If that is you, look at the Sector. For the fit, fast rider who wants to climb well and descend confidently on an XC or downcountry bike, or who wants a wide-rim gravel wheel with real engagement, this is the Whisp to buy.

Fit and compatibility
The Whisp Carbon System is built in 29in, which Industry Nine also labels 700c for gravel use; it is the same rim. Front axle choices are 12x100, 15x110, 15x110 with RockShox Torque Caps, and QRx100. Rear axle choices are 12x142, 12x148 Boost, and QRx135.
Driver options are Shimano HG, Shimano Micro Spline, SRAM XD, and Campagnolo N3W. If you are ordering a front wheel on its own, pick None (front wheel only) as the driver; a front hub has no freehub body. We check every axle and driver selection against your frame, fork, and cassette before the order is placed.
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.

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
When you order a Whisp Carbon System wheelset through ProWheelBuilder, Industry Nine builds it to your color and axle spec in Asheville, North Carolina, and ships it in roughly two weeks. We are an independent wheel shop in Georgia, not the manufacturer; what we add is a second set of eyes on the axle, driver, and brake choices so the wheel that shows up bolts straight onto your bike.
If you like the Solix hub but want a different rim, a 32-hole build, or a steel-spoke wheel we can true and re-tension in-house, we also build custom wheels on Industry Nine hubs through our Custom Wheel program.
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.
Full terms are on our Policies & Warranty page.
Whisp Carbon SYSTEM questions
Is ProWheelBuilder the manufacturer of the Whisp Carbon System wheelset?
No. Industry Nine designs and builds this wheel in Asheville, North Carolina, using Convergence carbon rims made by We Are One in Kamloops. ProWheelBuilder is an authorized reseller and checks your spec before the order goes in.
Can I run the Whisp Carbon System on a gravel bike?
Yes. Industry Nine lists the rim as 29in and 700c because they are the same size, and the hub is offered in 12x100 front and 12x142 rear, which covers most modern gravel frames. A 40 to 50mm gravel tire suits the 29mm internal width well.
How is the System version different from the Whisp Carbon Classic?
The System uses Industry Nine's machined aluminum straight-pull spokes and a straight-pull Solix hub shell, and lets you choose spoke color as well as hub color. The Classic uses a J-bend Solix hub with black Sapim Race steel spokes. The System build is lighter and stiffer; the Classic is easier to service with off-the-shelf spokes.
What is the engagement on the Solix System hub?
Industry Nine lists 605 points of engagement, or 0.59 degrees, from a five-pawl, 121-tooth drivering.
Can I mix hub and spoke colors?
Yes. Hub color and spoke color are separate choices, seven anodized options each, so a black hub with orange spokes or a purple hub with silver spokes are both possible.
What is the warranty?
Industry Nine covers Convergence carbon rims for life, including riding impact damage, and the Solix hub with a five-year limited hub warranty.
