Abstract
A bicycle derailer assembly that is mounted concentrically with an axle of a rear wheel assembly. The derailer is constructed to be mounted to the bicycle such that the derailer is pivotable about a common axis with the rear wheel and such that the rear wheel can be removed from the bicycle without interfering with the connection of the derailer to the bicycle. The derailer system provides a derailer that is robust and reduces interference of the derailer with the performance of bicycle maintenance.
