This eccentric ENO hub is made specifically for bikes with vertical dropouts. Chain tension with vertical frames can be addressed three ways; by using a chain tensioner, using an eccentric bottom bracket, or with the eccentric ENO.
This hub allows a rider to adjust 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.
Eccentric Caliper Mount Adaptor: For post mount disc brakes and to be used in conjunction with the Eric's Eccentric ENO disc hub. When installed the adaptor will allow the caliper mount to move in the same arc as the movement of the hub/brake rotor allowing the caliper and rotor to be properly aligned
This Eccentric Disc model has an standard ISO six bolt rotor on the non-drive side and is freewheel compatible on the drive side.
Made in the USA
