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.
