Bicycle sprocket assembly

A bicycle sprocket assembly comprising:

• a plurality of sprockets, one sprocket of the plurality of sprockets being a separate member from another sprocket of the plurality of sprockets;
• a sprocket support member configured to support at least one sprocket of the plurality of sprockets, the sprocket support member being a separate member from the plurality of sprockets, the sprocket support member comprising:
• a central cylindrical portion comprising a hub engagement profile to engage with a bicycle hub assembly;
• and
• a plurality of sprocket support portions extending radially outwardly from the central cylindrical portion with respect to a rotational center axis of the bicycle sprocket assembly, at least two sprocket support portions of the plurality of sprocket support portions being spaced apart from each other in a circumferential direction about the rotational center axis, at least one sprocket support portion of the plurality of sprocket support portions comprising:
• at least one axially extending surface extending in an axial direction parallel to the rotational center axis;
• an interior cavity;
• and
• a cover portion to form the interior cavity, the interior cavity being provided between the cover portion and the at least one axially extending surface.

A bicycle sprocket assembly comprising:

• a sprocket support member configured to support at least one sprocket that is a separate member from the sprocket support member, the sprocket support member comprising:
• a central cylindrical portion;
• and
• a plurality of sprocket support portions extending radially outwardly from the central cylindrical portion with respect to a rotational center axis of the bicycle sprocket assembly, at least two sprocket support portions of the plurality of sprocket support portions being spaced apart from each other in a circumferential direction defined about the rotational center axis, at least one sprocket support portion of the plurality of sprocket support portions comprising:
• a plurality of radially extending surfaces extending radially relative to the rotational center axis to support at least one of the at least one sprocket;
• a plurality of axially extending surfaces extending in an axial direction parallel to the rotational center axis, the plurality of radially extending surfaces and the plurality of axially extending surfaces providing a stepped shape;
• an interior cavity;
• and
• a cover portion to form the interior cavity, the interior cavity being provided between the cover portion and at least one axially extending surface of the plurality of axially extending surfaces.
