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.
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
