    摘要： A bicycle rim comprises a tire-attachment portion, an inner peripheral portion, a first side portion, a second side portion, and a first non-contact printed deposit. The inner peripheral portion is provided radially inwardly from the tire-attachment portion with respect to a rotational center axis of the bicycle rim. The first side portion includes a first curved surface. The first non-contact printed deposit is at least partly provided on the first curved surface. A first tangential line is defined on the first curved surface in which the first non-contact printed deposit is provided. A first surface angle is defined by the first tangential line and a reference plane perpendicular to the rotational center axis. The first surface angle is larger than 30 degrees.

    摘要： A bicycle derailleur includes a base member, a movable member, a link member, a chain guide, a biasing mechanism and a switching member. The link member movably couples the movable member to the base member. The chain guide is pivotally coupled to the movable member about a pivot axis. The biasing mechanism is operatively disposed between the movable member and the chain guide, and biases the chain guide with respect to the movable member about the pivot axis in a first direction in a biasing state. The switching member is configured to selectively switch the biasing mechanism between the biasing state and a releasing state. The biasing mechanism biases the chain guide less in the releasing state than the biasing state. The switching member is disengaged from the biasing mechanism in the biasing state. The switching member is engaged with the biasing mechanism in the releasing state.

    摘要： A bicycle sprocket is provided that is configured to limit a chain separation. The bicycle sprocket includes a sprocket body and a plurality of teeth. The sprocket body has a rotational center axis. The plurality of teeth includes a first tooth having a first width extending in a rotational center axis direction, and a second tooth having a second width extending in the rotational center axis direction. The second width is smaller than the first width. The plurality of teeth includes a base body and a nickel plating layer. The nickel plating layer covers at least a portion of the base body. The nickel plating layer includes at least one of phosphorus and boron.
