Phil Wood Track Pro Low Flange Fixed Fixed Rear Hub
The Phil Wood Pro track low-flange hub is the small-flange track hub in Phil's Pro specification: the same San Jose, California machining and full-contact sealed bearings as the standard low-flange hub, with Carbonyte low-drag bearings, a 7075 aluminum axle, titanium bolts and RLR multi-drilled flanges. It is the hub for velodrome racers and fixed-gear riders who want the lowest drag and lightest Phil track hub. This page covers the Phil Wood Track Pro Low Flange Fixed Fixed Rear Hub.
The Phil Wood Pro track low-flange hub comes from us only as a finished wheel: pick the rim, spokes and nipples, and we lace, tension and true it by hand in Georgia before it ships.
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 track wheel rolls with noticeably less drag than the standard hub thanks to the Carbonyte bearings, which on a velodrome is worth having, and it keeps the permanence Phil hubs are known for. It is the Phil track hub for racing.

About this listing
What sets this listing apart from the other Pro track low flange versions: rim-brake rotor mount, Bolt On 10x120mm, Bolt On 10x126mm, Bolt On 10x130mm, 24h, 28h, 32h drilling, about 280g, in polished, black. Pick the one that matches your frame and rotor and the rest of the hub is identical.
No rotor mount here: this is the rim-brake version of the Pro track low flange, which drops the disc flange and the weight that goes with it. It suits rim-brake road, touring and track frames and it is often the lightest hub in the family. Disc-brake frames need one of the disc versions listed separately.
Sizes, fit and compatibility
The Phil Wood Track Pro Low Flange Fixed Fixed Rear Hub comes in the drillings listed on this page in 100mm front and 120mm rear bolt-on spacing, fixed or fixed/free. J-bend spokes in any gauge; we build most track wheels with DT Champion or Sapim Race and Laser spokes and brass nipples.
It pairs naturally with the H Plus Son Archetype and TB14, Velocity Deep V and Fusion, and any track rim in the catalog that matches its drilling. Pick track or fixed-gear as your bike type in the configurator and it recommends a spoke count and lacing pattern.
Build it into a wheel
This hub is live in our Custom Wheel Program for track and road single-speed builds. Start a build with the Phil Wood Track Pro Low Flange Fixed Fixed Rear 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.
Testing, standards and warranty at Phil Wood
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.
Phil Wood states its Standard bearings are stainless steel cartridge bearings with a 100% Phil Waterproof Grease fill and full contact seals; Carbonyte bearings use a 30% Carbonyte grease fill with a partial contact seal and are not recommended for year-round mountain biking or touring. Shouldered axles position the bearings so no adjustment is required. Shells are 6061 aluminum with 7075 axles and end caps; the front touring hub weighs 202 g. Rider-plus-bike limits are 280 lb / 127 kg (Classic) and 190 lb / 86 kg (Pro).
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.

Building it at ProWheelBuilder
Phil Wood makes the Pro track low flange; ProWheelBuilder is an independent custom wheel builder in Georgia and not the manufacturer. We measure the rim before we cut a spoke, bring the wheel up in three or four rounds with a gauge, stress-relieve it between rounds and true it last, then tape it and fit a valve if you want it tubeless.
Only compatible hubs and spokes appear in the configurator, impossible combinations are struck through rather than hidden, and the price is 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. If we lace this into a wheel for you, that wheel also carries ProWheelBuilder's own one-year warranty, which covers broken spokes regardless of cause and all wheel-related labor, including truing and rebuilding, for a year from purchase. Where a rim or hub is covered by its maker, we make the manufacturer's claim for you and coordinate it; where it is not, we offer an eligible replacement rim or hub at 25% off current retail. Shipping to and from us is the customer's. This cover does not extend to wheels built from components you supply yourself.
Full terms are on our Policies & Warranty page.
Track Pro Low Flange Fixed Fixed Rear Hub questions
Can I use this hub with disc brakes?
No - this is the rim-brake version and it has no rotor mount at all, which is exactly why it is lighter and simpler. It is the one for a rim-brake road, track or classic frame. A disc frame needs one of the disc versions of this hub, which are listed separately.
Which spokes and nipples suit the Pro track low flange?
For most riders a double-butted spoke such as Sapim Race or DT Competition with brass nipples; lighter riders can go to Sapim Laser or CX-Ray. The configurator recommends a gauge and count for the Pro track low flange from your bike type and weight.
Low flange or high flange?
High flanges shorten the spokes for a stiffer wheel and a classic track look; low flanges are lighter and a touch more compliant. Phil makes both.
Fixed or fixed/free?
Fixed for the velodrome and pure fixed-gear riding; fixed/free flips between a fixed cog and a freewheel.
What spacing?
100mm front and 120mm rear, the track standard, with bolt-on axles.
Is the low-flange hub made in the USA?
Yes. Every Phil Wood hub is machined and assembled in San Jose, California.
Which axle spacing does it fit?
Bolt On 10x120mm Rear or Bolt On 10x126mm Rear or Bolt On 10x130mm Rear. Measure between the inside faces of your dropouts if you are unsure, or text us.
