Abstract: Embodiments of a front derailleur gear shifting system including various unique chain guides attached to and operating from a single pivot point. This derailleur system provides a simple, yet, elegant and robust improvement in shifting technique over conventional, lateral motion front derailleurs. Embodiments of open and closed annulus chain guides having specially shaped lifting and pulling surfaces for acting upon a bicycle chain during shifting are also disclosed. Additionally, as an optional enhancement, a dual-sided chain catcher that prevents unintended over-shifts in either direction is disclosed.

Abstract: A bicycle derailleur for operating a chain guide. The derailleur has primary actuator that imparts a primary displacement on the chain guide that has at least a component in an axial direction with respect to an assembly of toothed wheels. The derailleur also has secondary actuator that imparts a secondary displacement on the chain guide that has at least a component in a radial direction with respect to the assembly of toothed wheels. The secondary actuator can operate independently of the primary actuator.

Abstract: The present invention relates to a bicycle derailleur gear, particularly a front derailleur gear, with improved reliability that comprises a kinematic mechanism in the form of a four-bar linkage with a base body and a mobile body connected together through a pair of connecting rods hinged to the base body and to the mobile body at four pin elements, the mobile body carrying a chain guide, the four-bar linkage-kinematic mechanism being associated with derailleur gear actuation means suitable for deforming the four-bar linkage-kinematic mechanism so as to determine a displacement of the mobile body with respect to the base body and consequently a displacement of the chain guide, the derailleur gear actuation means being of the motorized type and comprising a motor casing and an outlet shaft that projects directly from said motor casing and characterized in that the actuation means command a translation in the axial direction of the outlet shaft with respect to the motor casing and are mounted between distinct components of the four-bar linkage-kinematic mechanism through interposition of at least one tilting interface about a fifth pin element substantially parallel to the pin elements.

Abstract: A front derailleur is basically provided with a base member, a chain guide, a link mechanism and a cable guiding structure. The base member is fixedly coupled to a bicycle. The chain guide is configured to guide a chain. The link mechanism movably couples the chain guide to the base member between a retracted position and an extended position in response to movement of an operation cable. The link mechanism includes a cable attachment portion that is configured to be attached to the operation cable. The cable guiding structure guides the operation cable from the cable attachment portion. The cable guiding structure is disposed on at least one of the base member and the link mechanism. The cable guiding structure has a cable exit that is arranged such that the operation cable exits forwardly from the cable guiding structure towards the front of the bicycle.

Abstract: A bicycle front shifting system includes operable to transmit a wireless signal, a crank assembly with two crank arms and a pedal on each of the two crank arms. The crank assembly is rotatable about a rotation axis. A front shift unit is coupled to the crank assembly and is rotatable about the rotation axis. The front shift unit includes a chain ring component with a big chain ring and a small chain ring. The small chain ring has a small diameter and the big chain ring has a big diameter that is larger than the small diameter. A shift mechanism is coupled to and rotatable with the chain ring component about the rotation axis. The shift mechanism is configured to receive the wireless signal from the shifter and to shift a chain between the big chain ring and the small chain ring according to the wireless signal.
