Abstract: A bicycle chain guide includes a first guide plate, a second guide plate, a first connection part and a second connection part. The first guide plate has a first chain engagement surface and the second guide plate has a second chain engagement to form a chain receiving area. The first and second connection parts extend between the first and second guide plates to connect the first and second guide plates together at first and second spaced locations, respectively. The first connection part is fixed to the first guide plate by a fastener. The first guide plate has a first abutment and the first connection part has a second abutment. The first and second abutments are arranged at a rear end of the chain guide to limit relative movement of the first and second guide plates.

Abstract: The present invention relates to a benzazepinone compound represented by the following formula (I): wherein R1 represents a C1-C6 alkyl group or halogeno C1-C6 alkyl group, R2 represents a carboxyl group which may be protected, and Y represents a group represented by the formula (II): wherein Z represents CH or a nitrogen atom, or a pharmaceutically acceptable salt thereof.

Abstract: A manually operated bicycle front derailleur assembly includes a linkage assembly, a lever member and a connecting link. The linkage assembly is supported to a fixing member and includes an inner link pivotally coupled to the fixing member at a first pivot point, an extension arm extending from proximate the first pivot point, an outer link pivotally coupled to the fixing member at a second pivot point, and a chain guide pivotally coupled to the inner and outer links to move between an inner shift position and an outer shift position. The lever member is pivotally supported relative to the fixing member and the bicycle frame spaced apart from the first and second pivot points. The connecting link operatively connects the lever member to the extension arm such that the linkage assembly moves in response to movement of the lever member.

Abstract: A bicycle front derailleur includes a fixed member, a chain guide and a linkage assembly. The fixed member includes a fixing body and a projection part fixedly coupled together. The fixing body includes a fastening portion with a seat tube reference plane that aligns with a longitudinal center axis of a seat tube when coupled thereto. The projection part has a projecting surface offset axially from the fixing body toward a smallest front chain ring of a bicycle front crankset. The projecting surface has an overall vertical height lying substantially in a single plane measured in a direction parallel to the seat tube reference plane that is greater than 10 millimeters in an area between the seat tube reference plane and 23 millimeters measured perpendicularly and forwardly from the seat tube reference plane.

Abstract: A front derailleur is provided with an auxiliary bicycle shifting component to minimize reduction in downshifting performance when a chain is located on a chain-entry side of a chain guide. The auxiliary bicycle shifting component basically has a fixed part and a chain contact part. The fixed part is used to fix the chain contact part on the chain guide. The chain contact part is disposed on the chain-entry side of an outer plate of a chain guide of the front derailleur, and is configured and arranged to contact with a chain.
