The ETR-B is back! This bottom bracket chain tensioner does what no other chain tensioner can do. By applying the spring tension around the chainring, it allows the rear drop out area to be simple, uncluttered and lighter. No more deraillers sticking out and getting caught in anything! This can be used with or without our current arsenal of tensioners.

Fitment Warning: This mounting configuration will require that the frame does not have: ISCG Tabs nor pressed in BB. Carbon frames with a different  Outside Diameter will also affect the fitment of the Adapter.
