An eccentric bottom bracket for a bicycle. The eccentric bottom bracket includes opposing first and second members. The first member and the second member each include a body and a flange. Each body is sized and shaped to penetrate an opening of a bottom bracket shell of a bicycle. Each flange is sized and shaped to prevent complete admittance of the member into the bottom bracket shell. Each body also has a bearing guide with an axis that is parallel to but offset from a center axis of the bottom bracket shell when that body is fit into the bottom bracket shell. The eccentric bottom bracket also includes a tightening assembly for selectively applying a compressive force between the body of the first member and the body of the second member. The compressive force secures the first member and the second member to the bottom bracket shell.
