EBB Tool

Adjust EBB


Eccentric Bottom Bracket (EBB) is often seen on internal gear or single speed systems. By rotating the EBB, you can change the distance from BB center to rear axle. As a result, you can tension the chain or belt without a rear derailleur or tensioner.

To help professional bike shops or internal gear / single speed bike fans adjust the EBB more conveniently, we develop this special tool.

100% match the Blacksnow EBB frameset, made of stainless steel.
