White Industries ENO Fixed Free Rear Hub
The White Industries ENO is the single-speed hub with a trick: the eccentric version has its axle offset in the shell, so rotating the hub in the dropouts tensions the chain, which lets you run a single speed on a frame with vertical dropouts and no tensioner. It also comes in a standard-axle fixed/free version and a 6-bolt disc version, all machined from 6061 aluminum in Petaluma, California, with Enduro sealed cartridge bearings, White Industries' freewheel or fixed threading, and anodized colors. This page covers the White Industries ENO Fixed Free Rear Hub.
The ENO 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 trick in the ENO is geometric: the eccentric version carries its axle offset in the shell, so rotating the hub in the dropouts takes up chain slack. That is what lets a single speed run on a frame with vertical dropouts and no tensioner at all. It is machined from 6061 in Petaluma on Enduro sealed cartridge bearings, and also comes as a standard-axle fixed/free hub and a 6-bolt disc version.
White Industries is open that it is not the biggest manufacturer in cycling and has no interest in being. A hub like this one, which solves a narrow problem properly instead of a broad one approximately, is what a small shop is for.
How it rides
An ENO makes a single-speed wheel that simply works. The eccentric version solves the chain-tension problem on a converted road or mountain frame, the bearings roll for years, and the hub takes a White Industries freewheel or a fixed cog and lockring. It is the hub we suggest for single-speed conversions, fixed-gear road bikes and single-speed mountain bikes with vertical dropouts.

Which version this is
Version notes. Rim-brake rotor mount, Eccentric Bolt On 10x130mm, Eccentric Bolt On 10x135mm, Straight Bolt On 10x130mm, Straight Bolt On 10x135mm, 28h, 32h, 36h, about 268g, in polished, black. If your frame or fork uses a different standard, the other versions of the ENO on this site cover it.
This is the rim-brake ENO, with no rotor mount at all: a lighter, simpler shell for road, track and classic frames that stop on the rim. It builds into the lightest wheel the model can make and it is the version to choose for a rim-brake bike; the disc versions of the same hub have their own listings.
Sizes, fit and compatibility
The White Industries ENO Fixed Free Rear Hub comes in the drillings listed on this page with the axle and brake options shown in the configurator: eccentric or standard axle, 6-bolt disc or rim brake, in 120, 130 and 135mm spacing. J-bend spokes in any gauge; we build most ENO wheels with DT Champion or Sapim Race spokes and brass nipples.
It pairs naturally with the H Plus Son Archetype and TB14, Velocity Deep V and Chukker, Stan's Crest and any rim in the catalog that matches its drilling. Pick single speed or fixed-gear as your bike type in the configurator and it recommends a spoke count and lacing pattern.

White Industries's testing and certifications
White Industries states that every hub is CNC-machined, hand-assembled, and inspected in its Petaluma, California facility, keeping “machining, assembly, quality control, and operations under one roof”. Founded in 1978 with about 20 employees, the company says it has been designing, machining, assembling, and testing components in Northern California for more than four decades in a 100% solar-powered shop using domestically sourced raw materials. It publishes no load, fatigue, or salt-spray test figures.
White Industries states it has partnered with Enduro on bearings since 1996. Hubs ship with Enduro high-carbon chromium steel sealed cartridge bearings (two 17287 in the CLD front; four, including 61902-LLU/LLB, in the CLD rear); the Enduro XD-15 upgrade with ceramic balls in nitrogen-infused super-stainless-steel races carries a limited lifetime warranty. Shells are 6061-T6 aluminum, polished then anodized; bearing preload is adjustable and hubs are described as easily serviceable and rebuildable. Weights: CLD front 146 g, CLD rear 280 g, T11 rear 248 g.
The Warranty & Returns page states a limited five-year warranty to the original owner, excluding normal wear, misuse, improper installation, and labor; proof of purchase is required and return shipping is covered within 90 days of purchase. Older instruction pages still cite one year, with bearings 60 days.

Building it at ProWheelBuilder
White Industries makes the ENO; 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 ENO drilling, strikes through combinations that are not made, and prices the wheel live.
Warranty
Manufacturer's warranty. White Industries warrants this product against defects in materials and workmanship. The duration, conditions and claim process are set by White Industries and can change without notice, so ask us and we will confirm the current terms before you buy.
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.
ENO Fixed Free 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.
What does eccentric mean on the ENO?
The axle is offset in the hub shell, so turning the hub in the dropouts changes the chain tension. It lets you run a single speed on vertical dropouts with no tensioner.
Fixed or free?
The ENO takes a White Industries freewheel on one side and a fixed cog with lockring on the other on the fixed/free version; the disc version is freewheel only.
Which spacing?
120mm for track frames, 130mm for road, 135mm for mountain; selectable in the configurator.
Is the ENO rebuildable?
Yes. Like every White Industries hub, every part is replaceable and spares are stocked for decades.
Is ProWheelBuilder the manufacturer of the White Industries ENO Fixed Free Rear Hub?
No. White Industries 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?
Eccentric Bolt On 10x130mm Rear or Eccentric Bolt On 10x135mm Rear or Straight Bolt On 10x130mm Rear or Straight Bolt On 10x135mm Rear. Measure between the inside faces of your dropouts if you are unsure, or text us.
