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, the ENO Disc hub takes a standard threaded freewheel on one side and an ISO 6 bolt disc rotor on the other. The ENO hub comes in three axle variations, each using the same hub shell: one with an eccentric axle, and two with straight axles. 

The eccentric axle ENO disc hubs are called “ENO ECC Disc” hubs, and allow you to convert your vertical dropout frame to singlespeed or fixed gear, offering 20mm of total fore-aft adjustment.  This comes in a 135mm axle width and uses bolts with stepped washers to hold the hub in the frame.

The straight axle ENO disc hubs are simply called “ENO Disc” 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 135mm and 12mm x 142mm Thru.  The 135mm axle width uses 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.

 NOTE: You may need to also purchase the “ENO Eccentric ISO Disc Caliper Adapter” (Part # ECCALMOUNT available in Hub Parts). As the ENO ECC Disc hub moves through its eccentric adjustment, your brake rotor is also moving along the same path and can cause a situation where the rotor is either too close to (and possibly hitting) the caliper or too far away to retain proper pad/rotor contact.  This adaptor allows you to get the caliper back where it belongs. 

In some situations you may not need this adapter and you’ll find that just by luck your caliper and rotor end up in a position that works fine.  So if you’re nor sure, just try things without it first.

 *We do not offer the 12mm x 142mm Thru axle version with an eccentric axle because it would require a completely new hub design.
