Phil Wood Pro Rear Centerlock Disc Hub
The Phil Wood Pro is the top of Phil Wood's range: the same San Jose, California machining and full-contact sealed bearings as every Phil hub, with Carbonyte low-drag bearings, a 7075 aluminum axle and end caps, titanium bolts and RLR multi-drilled flanges that let one hub be built in several spoke counts. It comes in road rim-brake, 6-bolt disc and centerlock disc versions, and it is the Phil Wood hub for riders who want the durability without the touring hub's weight. This page covers the Phil Wood Pro Rear Centerlock Disc Hub.
The Phil Wood Pro 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
Phil Wood's bearings are the point. They are full-contact sealed cartridge bearings, meaning the seal rubs the inner race rather than floating above it, which adds a little drag and keeps water out completely; packed with Phil's own waterproof grease, they run for years in the worst conditions. The touring hub uses a 6061 axle and 6902 bearings, with a Carbonyte low-drag bearing upgrade available, and the shell is machined thick because a touring hub is not where weight is saved. Wide flanges give the rear wheel lateral stiffness under a load.
How it rides
A Phil Wood Pro rolls with less drag than the touring hub thanks to the Carbonyte bearings, engages quietly, and keeps the permanence Phil hubs are known for. It is the hub for a road, gravel or light-touring wheel that the customer intends to keep for decades, on an HED Belgium, Velocity Quill or Mavic Open Pro.

Which version this is
Version notes. Centerlock rotor mount, QR 5x135mm, Thru Axle 12x142mm, Thru Axle 12x148mm Boost, 24h, 28h, 32h, about 427g, in polished, black. If your frame or fork uses a different standard, the other versions of the Pro on this site cover it.
This is the centerlock Pro: 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 Phil Wood Pro Rear Centerlock Disc Hub comes in the drillings listed on this page with the axle and brake options shown in the configurator: rim brake in 130mm, 6-bolt or centerlock disc in 135 and 142mm. J-bend spokes in any gauge; we build most Phil Pro wheels with Sapim Race, Laser or CX-Ray spokes or DT Competition and brass nipples.
It pairs naturally with the HED Belgium R and G, Velocity Quill and A23, Mavic Open Pro UST, H Plus Son Archetype and Boyd Altamont. 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, touring, mountain bike, MTB single-speed and fat bike builds. Start a build with the Phil Wood Pro Rear Centerlock Disc Hub and the configurator opens with this exact hub pinned at the top of the Phil Wood list — you choose the rest of the parts and it validates every combination as you go.
Phil Wood's testing and certifications
Phil Wood & Co. states it was founded in 1971 and that its products are “completely designed, manufactured and assembled in San Jose, California”, machined from US-produced materials on CNC machining and turning centers with diamond-tipped tools. The company says a front hub shell passes through seven production stations before assembly, and that it specifies every bearing it uses, many made exclusively to its specifications. It publishes no load, fatigue, salt-spray, or ISO/EN figures.
The warranty page states a lifetime limited warranty against manufacturing defects for the original owner, one year on all bearings, and one year on Classic stainless cassette bodies and Pro aluminum parts; normal wear, contamination, misuse, modification, improper maintenance, and incorrect reassembly are excluded, with proof of purchase required.
current cassette hubs use 5 double-row heat-treated stainless steel pawls on a 40-tooth ratchet ring (earlier 4-pawl, 20-tooth hubs can be upgraded by the service department); Pro cassette bodies are hard-anodized 7075 aluminum; the Pro 11-speed rear hub weighs 331 g. Ratchet wear is excluded from warranty.

Building it at ProWheelBuilder
Phil Wood makes the Pro; 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 Pro drilling, strikes through combinations that are not made, and prices the wheel live.
Warranty
Phil Wood's warranty. Phil Wood & Co. gives the original owner a limited lifetime warranty against manufacturing defects, with a one-year guarantee on bearings, stainless cassette bodies and aluminum Pro parts. Proof of purchase from an authorized dealer is required, and bearings that fail from contamination or lack of maintenance are not covered.
ProWheelBuilder. Built into a wheel by us, this part is covered by our own one-year wheel warranty on top of the maker's. For a year we replace broken spokes whatever caused them, and we cover the labor on the wheel - truing, re-tensioning, a rebuild if it needs one. If a rim or hub fails and its maker covers it, we run that claim for you; if the maker says no, you get an eligible replacement rim or hub at 25% off retail. You pay the shipping each way. Wheels built from parts you send us are excluded.
Full terms are on our Policies & Warranty page.
Pro Rear 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 RLR drilling?
Phil's multi-drilled flanges, which carry more than one spoke-hole pattern so a single hub can be built in several spoke counts.
What are Carbonyte bearings?
Phil Wood's low-drag sealed bearings, which keep the full-contact seal but roll with noticeably less resistance than the standard bearings.
Pro or touring hub?
Pro for road, gravel and light touring where weight and drag matter; touring hub for loaded touring and tandems where strength is everything.
Which freehub bodies fit the Pro?
Shimano HG and SRAM XDR, selectable in the configurator.
Is ProWheelBuilder the manufacturer of the Phil Wood Pro Rear Centerlock Disc Hub?
We are not. Phil Wood 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 or Thru Axle 12x148mm Boost Rear. Measure between the inside faces of your dropouts if you are unsure, or text us.
