Description

For frame builders who want to use the EBB standard. Because they can adjust the chain's tension, EBBs allow for a myriad of setups on any given bike frame. Note: the EBBdoes not come with a way to secure the Eccentric BB in the shell, a retention mechanism must be added by the builder.
