METHOD OF MOUNTING A DERAILLEUR ON THE BASE OF A BICYCLE FRAME

摘要

The derailleur is shown in a retracted position allowing the dismantling of the rear wheel of the cycle. In this retracted position, it is maintained by an abutment which is rigid with the fixed part of the derailleur and is resiliently retained in a cavity defined by the concavity of a resiliently yieldable strip carried by a member fixed to the frame lug. In the operative position, the abutment is applied against the support surface of the lug.
