摘要： A gear indicator for use on a bicycle is provided remotely from the shift operating device. The gear indicator is coupled to a shift operating device via an indicator cable. The gear indicator basically includes a housing with an indicator member slidably coupled to the indicator cable with in the housing. The location of the indicator member relative to the housing indicates a gear currently engaged by the chain. In the most preferred embodiments, an indicator member is frictionally mounted on the inner wire of the indicator cable for automatically adjusting of the indicator member in the event that the cable becomes elongated or the indicator member becomes misaligned. The housing has a biasing member coupled between one wall of an interior cavity and the first end of the inner wire of the cable indicator for biasing the indicator member to one of its end positions. An abutment or stopper is provided within the housing to engage indicator member to automatically adjust the indicator member along the cable in the event that the cable becomes elongated or the indicator member becomes misaligned. In other embodiments, a gear position indicia portion of the housing is frictionally coupled to the housing for manually or automatically adjusting the gear position indicia relative to the indicator member.

摘要： A bicycle operating device is provided with a position maintaining arrangement that selectively maintains a movable member in any one of a plurality of holding positions relative to a fixed member. The moving arrangement selectively moves the movable member in a first moving direction from a current holding position to another one of the plurality of holding positions. The first operating member moves in a first operating direction from a rest position to a first end position, and moves in a second operating direction from the rest position to a second end position. The movable member is moved by a different number of the holding positions in the first moving direction when the first operating member moves from the rest position to the first end position as compared to when the first operating member moves from the rest position to the second end position.

摘要： A bicycle crank axle comprises an axle body having first and second end portions, a plurality of first splines disposed at the first end portion of the axle body, a plurality of second splines disposed at the second end portion of the axle body, and a projection extending radially outwardly from the first end portion of the axle body, wherein the projection is structured to abut against a lateral outer surface of a bicycle crank arm to prevent the bicycle crank arm from moving axially outward. A separate projecting member is mounted to the first end of the axle body to form the projection. The plurality of first splines extend radially outwardly from an outer peripheral surface of the axle body for engaging a splined surface of the bicycle crank arm, but the plurality of second splines do not extend radially outwardly relative to the outer peripheral surface of the axle body.
