Velocity Race Front 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. This page covers the Velocity Race Front 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 sold here only inside a wheel we build. Choose the rim, spokes and nipples in the configurator and the finished wheel ships from Georgia laced, tensioned and trued by hand.
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 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.
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 Velocity Race hub 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
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.
A front wheel is where you feel a hub least and a build most. With no drive torque to carry, the front Velocity Race hub can be laced two-cross or even radial on the non-rotor side on a rim-brake bike, which makes a lighter, more direct-feeling wheel; on a disc bike we lace both sides crossed so the rotor's braking torque has spokes to pull against. Either way the front wheel is the one that steers, and a stiff, true front wheel is most of what makes a bike feel precise.

This version
This version is the centerlock hub in QR 5x100mm, Thru Axle 12x100mm, Thru Axle 15x100mm, drilled for 24h, 28h, 32h, 36h, about 145g, in black. Those are the only things that differ between the versions of the Velocity Race hub; the shell, bearings and seals are the same.
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
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. The configurator recommends spoke count and lacing from your bike type and weight.
Put it in a custom wheel

It is set up for gravel and road disc, mountain bike, MTB single-speed, fat bike, tandem and e-bike and touring builds.
How Velocity tests its hubs
Velocity USA offers hubs under its own name for road, gravel, mountain, touring, tandem and track use.
What Velocity does state: most hubs use cartridge bearings "with weather-resistant seals", and Race hubs add "double-bearing seals for added protection." Bearing preloads are set at the factory with no need for adjustment. Velocity cautions that "Sealed does not mean waterproof" - bearings that are submerged, pressure-washed or otherwise waterlogged should be serviced or replaced by a professional mechanic, and service depends on hub type. Velocity sells replacement sealed cartridge bearings in 6001, 6802 and 6902 sizes, offers loose-ball bearings as an option on custom wheels, and ships mountain disc hubs with parts to convert between 9 mm quick-release, 12 mm and 15 mm thru-axle.

Building it at ProWheelBuilder
The Race hub is assembled in Florida; ProWheelBuilder is an independent custom wheel builder in Georgia and not the manufacturer. Spokes are cut from the ERD we measure on the actual rim, the wheel comes up in stages on a tensiometer, and it is stress-relieved and trued before it goes in the box; tape and a valve go on if you ask.
The configurator filters to what fits, crosses out what is not made, and prices the build as you go.
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. Our one-year wheel warranty applies to any wheel we build around this part, alongside whatever the manufacturer offers. Inside that year, broken spokes are replaced no matter how they broke, and the wheel labor is ours - truing, re-tensioning or a full rebuild. A rim or hub failure that the maker covers, we claim for you and see through; one the maker declines, we answer with an eligible replacement at 25% off current retail. Shipping both ways is yours, and components you supply yourself fall outside this cover.

Race 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.
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.
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 ProWheelBuilder the manufacturer of the Velocity Race Front Black Centerlock Disc Hub?
No. Velocity 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 text 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.
