A bicycle front derailleur basically includes a base member, a chain guide, a linkage assembly and a support structure. The base member is configured to be mounted to a bicycle frame. The linkage assembly movably couples the chain guide to the base member to move relative to the base member between a retracted position and an extended position. The support structure includes a support member and a contact member. The support member is configured to be mounted to the base member and to advance toward the bicycle frame in a first direction. The contact member includes a contact part and a coupling part extending from the contact part. The contact part is configured to contact the support member and the bicycle frame. The coupling part is configured to be movably coupled to the base member.

A bicycle front derailleur is basically provided with a base member, a chain guide and a chain restricting abutment. The base member is configured to be mounted on a bicycle frame. The chain guide is configured to be movably coupled to the base member between a retracted position and an extended position to move a bicycle chain. The chain restricting abutment is configured to restrict the bicycle chain from moving in a radially outward direction of a rotational center axis of a bicycle front sprocket when the base member is mounted on the bicycle frame and the chain guide moves from the extended position toward the retracted position.

A bicycle frame includes a first frame member and a second frame member configured to be pivotally connected to the first frame member about a pivot axis. The first frame member includes a threaded hole, through which a fixing bolt for fixing a mounting member of a bicycle front derailleur to the first frame member passes, and an abutting portion configured to restrict rotation of a mounting member of a bicycle front derailleur around the fixing bolt by abutting the mounting member. The threaded hole is located on a front side of the pivot axis.

A bicycle bracket element connects a bicycle frame to a rear gearshift mechanism of a derailleur system. The bracket element includes a first portion which has a cutout for receiving a portion of a bicycle rear wheel axle and a second portion which has a mounting opening to which the rear gearshift mechanism can be secured. The bracket element is formed with a region made from plastic and a region made from metal. The region made from plastic is fixedly connected to the region made from metal.

A clamp configured for connecting a bicycle component to a tubular element of the bicycle. The body of the bicycle component has a through opening extending between surfaces of the body and a seat on one surface that connects with the through opening. The clamp has an annular band that is connected to a slider in the through opening. An actuation lever connected to the slider moves the slider between a release position and a clamping position. When the slider is in the claiming position, the actuation lever is position in the seat on the body.

A bicycle component including a main body and an associated clamping device for fixing the component to a tubular bicycle element is disclosed. The clamping device has a plurality of hinged clamping segments configured to be arranged around the tubular element and quickly secured by a removable fastener.
