Velocity Race Rear Black Centerlock Disc Hub
The Velocity Race hub is the lighter of the two hub lines the company assembles in Florida, and it is the hub we reach for when a customer wants a wheel that matches from rim to hub. The Race hub has a machined aluminum shell, sealed cartridge bearings and a pawl freehub, and it comes anodized in the same colors as the rims, which is something no other hub maker offers. This page covers the Velocity Race Rear Black Centerlock Disc Hub, the mountain-bike disc version in Boost or standard spacing with a centerlock or 6-bolt rotor mount.
These are not the lightest or the fanciest disc hubs we sell, but they are well made, easy to service, priced sensibly and available in a matching color, and for a lot of trail and gravel riders that is the whole brief.
The Velocity Race 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
The Race hubshell is machined from aluminum bar with conventional J-bend flanges and anodized in the color range. Bearings are sealed cartridge units in common sizes, replaceable with a bearing press when they eventually wear. The rear freehub runs pawls on a hardened ratchet ring for prompt engagement and swaps between Shimano HG, SRAM XD and Micro Spline bodies. End caps convert the Race hub between thru-axle and quick-release standards, and the configurator lists the axle and driver options for the version on this page.
The Race is lighter than the Standard hub because the shell is machined thinner and the axle is a lighter alloy; the flange spacing is the same, so the two build into wheels of similar stiffness.
The hubs are assembled at the same Jacksonville, Florida facility as the rims, which is why hub and rim colors match exactly and why the two are designed to be built together. The hubs use common cartridge bearing sizes and simple pawl freehubs that any shop can service, and spares stay available for years.
How it rides
A Velocity Race hub is quiet and undramatic. Engagement is quick enough for technical trail climbing, the bearings spin freely, and the seals keep grit out. It is happy under cross-country, trail and gravel use; for enduro, downhill or e-bike torque we would steer you to a heavier-duty hub.
The main reason to choose the Race hub over a DT Swiss 350 or Bitex is the color match with the rims, and a wheel built that way looks like it was made as a set because it was.

Which version this is
Version notes. Centerlock rotor mount, QR 5x135mm, Thru Axle 12x142mm, 24h, 28h, 32h, 36h, about 275g, in black. If your frame or fork uses a different standard, the other versions of the Velocity Race hub on this site cover it.
This is the centerlock Velocity Race hub: 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
The Velocity Race Rear Black Centerlock Disc Hub comes in the drillings listed on this page with the axle, rotor and driver options shown in the configurator. It takes J-bend spokes in any gauge; we build most Race hub wheels with DT Competition or Sapim D-Light spokes and brass nipples.
It pairs naturally with the Velocity Blunt 35, Blunt SS, Dually and Cliffhanger, and with any other rim in the catalog that matches its drilling. Tell the configurator your bike type and weight and it suggests a spoke count and lacing pattern to suit.
Build it into a wheel
This hub is live in our Custom Wheel Program for gravel and road disc, mountain bike, fat bike, tandem and e-bike and touring builds. Start a build with the Velocity Race Rear Black Centerlock Disc Hub and the configurator opens with this exact hub pinned at the top of the Velocity list — you choose the rest of the parts and it validates every combination as you go.
Velocity's testing and certifications
Velocity USA offers hubs under its own name for road, gravel, mountain, touring, tandem and track use. Velocity's product pages do not state where the hubs are manufactured, and the company publishes no bearing-life, freehub-durability, sealing, load or fatigue test figures and no third-party certification for hubs; the specification tables on its hub pages (weight, bearings, axles) are blank and refer customers to the tech page.
Warranty matches all Velocity products: defects in material and workmanship for the life of the product, excluding normal wear and tear, accidents, misuse, improper assembly or maintenance; repair or replacement at Velocity's discretion.
Velocity states cassette-body pawls should be inspected and lubricated once a year or more depending on use and environment; cassette bodies come in Shimano, SRAM XD/XDR and Campagnolo fitments.

Building it at ProWheelBuilder
The Race hub is assembled in Florida; 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 Race hub's drilling and color, strikes through combinations that are not made, and prices the wheel live.
Warranty
Velocity's warranty. Velocity warrants its rims against defects in material and workmanship for the life of the product, repairing or replacing at its option. Normal wear, accidents, misuse, improper assembly and poor maintenance are excluded.
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.

Race Rear 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.
What is the difference between the Race and Standard hubs?
The Race is lighter, with a thinner machined shell and lighter axle, and comes in colors; the Standard is the heavier, cheaper workhorse. Internals and flange spacing are similar.
Which freehub bodies fit the Race hub?
Shimano HG, SRAM XD and Shimano Micro Spline, selectable in the configurator for the rear hub.
Can I get the Race hub in a color to match my rim?
Yes. The factory anodises the Race hub in the same colors as its rims; the colors in stock are listed in the configurator.
Is the Race hub e-bike rated?
No. For e-bikes choose a hub with a full-contact or steel-reinforced freehub such as a DT Swiss 350 or Hope Pro 5.
Is ProWheelBuilder the manufacturer of the Velocity Race Rear Black Centerlock Disc Hub?
We are not. Velocity manufactures the hub; ProWheelBuilder's part is the wheel: measuring, lacing, tensioning and truing it here in Georgia.
Which axle spacing does it fit?
QR 5x135mm Rear or Thru Axle 12x142mm Rear. Measure between the inside faces of your dropouts if you are unsure, or text us.
