Industry Nine 1/1 Road Front Black Centerlock Disc Hub
This page covers the Industry Nine 1/1 Road Front Black Centerlock Disc Hub.
The 1/1 road hub is built to order here. Choose the rim, spokes and nipples in the configurator; the wheel leaves Georgia laced, tensioned and trued.
Design and construction
This is the front hub, and a front hub has no freehub. What matters here is the part of the hub that carries the wheel: the bearings, the seals, the axle and the two flanges, and the front 1/1 shares all of them with its rear partner. It is the simpler half of the pair and the one that runs longest between services. The driver and engagement story belongs on the rear hub's page; this page is about a front wheel that spins freely, stays sealed and builds stiff.
How it rides
It is the hub we suggest for a road or gravel disc wheel that has to last and does not need a boutique badge.
On the road or the trail the front hub's job is to disappear: spin freely, keep water out, and hold the flanges still so the wheel tracks where you point it. The front 1/1 does that with the same bearings and seals as the rear and none of the rear's complexity, and because a front wheel carries less load and no torque it stays true longer than the rear on the same rim. When the rear finally needs a look, the front usually does not.

Which version this is
Version notes. Centerlock rotor mount, QR 5x100mm, Thru Axle 12x100mm, Thru Axle 15x100mm, 28h, about 138g, in black. If your frame or fork uses a different standard, the other versions of the 1/1 on this site cover it.
This is the centerlock 1/1: the rotor sits on a spline and a lockring holds it, which saves weight over six bolts and makes swapping rotors a one-tool job. If your rotors are 6-bolt, a centerlock adapter fits them, or choose the 6-bolt version of the same hub.
Sizes, fit and compatibility
Centerlock rotors, 12mm thru-axle road spacing. J-bend spokes in any gauge; we build most 1/1 road wheels with Sapim CX-Ray, Laser or Race spokes or DT Aerolite and Competition and brass or alloy nipples.
It pairs naturally with DT Swiss RR and GR rims, HED Belgium, Boyd Altamont, Velocity Aileron, Nox Citico, ENVE G-Series and Reserve gravel rims that match its drilling. Tell the configurator your bike type and weight and it suggests a spoke count and lacing pattern to suit.
Put it in a custom wheel
Build a custom wheel around the Industry 9 1/1 Road Front Black Centerlock Disc Hub — the link drops you into our Custom Wheel Program with this hub pinned, ready for you to choose the rest. It is set up for gravel and road disc, mountain bike, MTB single-speed and fat bike builds.
Industry Nine's testing and certifications
Industry Nine states it "has been anodizing & machining hubs, spokes, and drive systems in Asheville, NC since 2004" and that it engineers and manufactures every component of its hub and wheel systems in-house, including hub shells, axles, spokes and anodizing: "If it moves inside an I9 hub, we made it." Coverage of the Hydra2 launch (March 2025) reports Industry Nine drew on data from over 100,000 Hydra hubs in use to redesign the hub, with a 65% thicker axle "engineered for superior stress dissipation", larger 6903 bearings throughout, a labyrinth channel and full-contact radial lip seals against contamination. Industry Nine publishes no bearing-cycle, salt-spray, ISO 4210 or laboratory test figures for its hubs.
Warranty: Industry Nine states "Hubs are covered for five years against defects in materials and workmanship." Years 0-2 include parts, labor and return shipping; in years 3-5 parts are covered and labor and shipping may apply. Warranties apply to the original purchaser only with proof of purchase from a certified dealer; bearings and other normal wear items are excluded. Industry Nine says service needs only basic tools, "no proprietary tools are required".

The figures, certificates and media above are Industry Nine's own. ProWheelBuilder does not run these tests; our part is the wheel we build on the hub.
Building it at ProWheelBuilder
Industry Nine makes the 1/1; ProWheelBuilder is an independent custom wheel builder in Georgia and not the manufacturer. The build is the same every time: measured ERD, spokes cut to the half millimeter, staged tensioning with a gauge, stress relief, a final true, and tubeless tape and a valve on request.
The configurator shows only rims and spokes that fit the 1/1 drilling, strikes through combinations that are not made, and prices the wheel live.
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. Any wheel we build on this part carries ProWheelBuilder's one-year warranty in addition to the manufacturer's. Broken spokes are replaced for a year whatever the cause, and all wheel-side labor is included - truing, re-tensioning, rebuilding. Where the maker covers a failed rim or hub we handle that claim for you; where they decline, an eligible replacement comes at 25% off current retail. The customer covers shipping in both directions. Components supplied by the customer are not covered.
Full terms are on our Policies & Warranty page.
1/1 Road Front Black Centerlock Disc Hub questions
Will my rotors fit this hub?
This is the centerlock version, so a splined centerlock rotor drops on and a lockring holds it - one tool, no six bolts to torque or lose. If your rotors are 6-bolt they will fit with a centerlock adapter, or take the 6-bolt version of the same hub, which is a separate listing.
Does the 1/1 road hub come in colors?
It is black. Industry Nine's color range is on the SOLiX and Hydra 2.
Is ProWheelBuilder the manufacturer of the Industry Nine 1/1 Road Front Black Centerlock Disc Hub?
No. Industry Nine makes the hub. ProWheelBuilder is an independent custom wheel builder in Georgia that builds it into a finished wheel to your spec.
Which axle spacing does it fit?
QR 5x100mm Front or Thru Axle 12x100mm Front or Thru Axle 15x100mm Front. Measure between the inside faces of your dropouts if you are unsure, or email us.
Does it need special spokes?
No. It takes standard J-bend spokes, which the configurator offers in every gauge and finish we stock.
How long will the wheel take?
Build time comes down to parts availability rather than bench time. The estimated ship date is shown in the configurator before you check out.
