Information

The ENO hub has long been synonymous with the White Industries brand and remains a sought after item.  “ENO” is “ONE” spelled backwards, the result of a machining program mistake we made years ago and decided not to correct.  Made from U.S. sourced 6061-T6 aluminum, it takes a standard threaded freewheel on one side and our proprietary splined fixed gear cogs on the other. The ENO hub comes in five axle variations, each using the same hub shell: two with eccentric axles, and three with straight axles. 

The eccentric axle ENO hubs are called “ENO ECC” hubs, and allow you to convert your vertical dropout frame to singlespeed or fixed gear*, offering 20mm of total fore-aft adjustment.  These come in either 130mm or 135mm axle widths and use bolts with stepped washers to hold the hub in the frame.

The straight axle ENO hubs are simply called “ENO” hubs.  These are designed to be used with frames that have either slotted horizontal dropouts, adjustable dropouts, or an eccentric bottom bracket.  They come in 130mm, 135mm and 12mm x 142mm Thru.  The 130mm and 135mm axle widths use bolts with stepped washers to hold the hub in the frame, while the 12mm x 142mm Thru axle version uses a 12mm Thru axle (supplied by you, to fit your frame) to hold the hub in the frame.

*While these hubs are referred to as “Flip Flop” hubs, they do not have the same chainlines on each side.  The freewheel side has a 47.5mm chainline and the fixed side has a 43mm chainline.  If you want to be able to use it as a flip flop, you would want to shoot for a chainline in the middle which is 45mm, and use an 8-speed 3/32″ chain.   

We do not offer the 12mm x 142mm Thru axle version with an eccentric axle because it would not work with this hub design.
