Abstract: A bicycle hydraulic brake actuation device includes a hydraulic master cylinder housing having a bore, a lever, a master piston and an adjuster. The lever is pivotally coupled to the hydraulic master cylinder housing for movement between an at rest position and a brake engagement position. The master piston is disposed within the bore and having an adjustment end. The adjuster is operably disposed between the adjustment end of the master piston and a portion of the lever. The adjuster is movable between a plurality of adjustment positions relative to the adjustment end such that with the lever in the at rest position, movement of the adjuster between the plurality of adjustment positions moves the master piston between a corresponding plurality of adjustment positions along an axial length of the bore.

Abstract: A bicycle front derailleur includes a chain guide that is provided with a pushing element that is movable relative to the chain guide to assist in shifting a bicycle chain from a smaller front sprocket to an adjacent larger sprocket. The chain guide is part of a movable member that is movably coupled to a base member via a linkage assembly. The pushing element is rotatably coupled to the chain guide portion and activated by a chain to move relative to the inner chain guide member from a first position with the pushing element at rest to a second position in response to activation by the chain. The contact surface moves laterally outwardly into the chain receiving slot toward the outer chain guide member as the pushing element moves from the first position to the second position.
