Abstract: A bicycle brake caliper apparatus comprises a caliper housing and a plug. The caliper housing includes a fluid chamber and an opening for receiving the plug therein, wherein the opening extends to an outside of the housing at a first location. The housing also includes a fluid passage in fluid communication with the fluid chamber, wherein the fluid passage is in fluid communication with an outside of the housing at a second location offset from the first location. The fluid passage is closed when the plug is in a first position. The fluid passage is open when the plug is in a second position so that fluid is allowed to flow from the fluid chamber, through the fluid passage and to the outside of the housing at the second location.

Abstract: A bicycle rim is provided with an annular tire mounting part, an annular spoke mounting part, at least one spoke attachment member and an orientation maintaining structure. The annular spoke mounting part includes a plurality of spoke openings a circumferential spaced along the annular spoke mounting part. The spoke mounting part extends from the annular tire mounting part to define an interior space containing the spoke attachment member. The orientation maintaining structure is dimensioned with respect to the interior space to form an orientation maintaining arrangement such that the spoke attachment member is slidably disposed within the interior space in a circumferential direction of the bicycle rim to selectively align with one of the spoke openings while also maintaining an orientation of the spoke attachment member within the interior space to align with the one of the spoke openings.

Abstract: A bicycle hub is provided that comprises a hub axle, a hub body rotatably mounted on the hub axle by a pair of bearings and at least one of the bearings having an inner tube. The bearings include an outer ring operatively coupled to the hub body, an inner ring operatively coupled to the hub axle, and a plurality of rolling components disposed between the outer ring and the inner ring. The inner tube is disposed with respect to the outer ring of at least one of the bearings such that at least a portion of the inner tube is disposed about the outer peripheral surface of the hub axle to form a small prescribed radial clearance therebetween.

Abstract: A bicycle sealing assembly is provided for a bicycle part having a fixed part and a rotational part mounted to rotate relative to the fixed part such as a bicycle hub. The rotatable member (hub shell and/or freewheel) is rotatable mounted on the fixed part (hub axle assembly) by a pair of bearing assemblies. The sealing assembly basically has first and second dust caps and first and second sealing members. The first dust cap is coupled to the rotatable member, while the second dust cap coupled to the hub axle. The first sealing member is disposed between the first dust cap and either the fixed part or the second dust cap to form a seal therebetween. The second sealing member is disposed between the second dust cap and either the first dust cap or the rotational part to form a seal therebetween.
