Abstract
An adjustable bottom bracket assembly for a bicycle comprises a body member and a wedge member, each having a circular cylindrical external surface in close fit with an internal circular cylindrical surface of a bottom bracket shell. The body and wedge members have abutting complementary planar wedge surfaces oriented obliquely to the axes of their cylindrical surfaces. A drive device, such as a screw, moves the body and wedge members axially to wedge them securely in an adjusted position in the bottom bracket shell.
