Singlespeed Hubs

Our 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 to use 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: Eric's Eccentric ENO and Eric's Eccentric Disc ENO. The Eccentric ENO is a flip/flop design fixed/free. The disc model is ISO standard six bolt on non drive side and freewheel compatible on drive side. We recommend running the eccentric disc ENO with the eccentric caliper mount adaptor featured below. Made in the USA

The eccentric caliper mount is designed to work with the Eric's Eccentric Disc ENO. The eccentric disc hub moves in an elliptical arc tensioning the chain. When running a disc brake the brake rotor moves in the same elliptical arc as the hub which creates a problem with the caliper / rotor interface. The eccentric mount replaces the caliper frame mount allowing the disc brake caliper to rotate in the same elliptical arc as the hub. The adaptor should work with post mount Hayes, Avid, and Shimano brakes. The original caliper frame mount will need to be unbolted from the caliper and replaced with the eccentric mount. The adaptor will NOT work with all disc brakes.
