Abstract
A derailleur is configured to be mounted to a bicycle frame. The derailleur includes a clamp mountable to the bicycle frame. The clamp includes a first end having a threaded portion receiving a clamp fastener for tightening of the clamp about the bicycle frame. A base member is connected to the clamp and includes a bore receiving the clamp fastener. A chain guide receives and laterally displaces a chain. First and second link members pivotably connect the base member and the chain guide. One of the link members includes an opening aligned with the bore such that the clamp fastener passes through the opening and into the bore of the base member.
