摘要

The rim has an internal hollow structure filled with core material (7), and a load bar (1) extending within the hollow structure for linking an outer side of spokes with a rim bed (4), where the spokes extend from the inner hollow structure up to the rim bed. The spokes are arranged parallel to each other along a curved surface of a spoke wall. The rim bed extends throughout the hollow structure and into the region of the load bar.
