The White Industries Eccentric ENO line of hubs are made specifically for bikes with vertical dropouts. The majority of bicycle frames made today are made with vertical dropouts, however converting the frame to a single speed presents the problem of how to tension the chain. Chain tension with vertical frames can be addressed three ways: by using a chain tensioner, using an eccentric bottom bracket, or with our Eccentric ENO. The Eccentric ENO is an easy, clean, and simple answer to the problem. The eccentric rear hub allows the rider to adjust the chain tension by simply rotating the elliptical axle ends up and back in the dropouts. As the hub rotates back, the chain is pulled into tension. The Eccentric ENO is available in two models: The Eric's Eccentric ENO and Eccentric Disc ENO. The Eric's Eccentric ENO is a flip/flop design fixed/free. The disc model has an ISO standard six bolt rotor on the non-drive side and is freewheel compatible on the drive side. We recommend running the Eccentric Disc ENO with the eccentric caliper mount adaptor featured below. Made in the USA.
