Abstract: A weight reduction means for a dual-wall rim includes a structural frame disposed in the rim, multiple through holes to receive insertion of respective spoke connectors being disposed at where the dual-wall frame is located relatively to the spoke connectors; and one or a plurality of through holes between any abutted existing through holes on the dual-wall frame being punched at the same time when those existing through holes are initially punched without affecting the structural strength of the entire dual-wall rim without changing locations and numbers of those spoke connecting holes disposed on the inner circumference of the rim while maintaining the structural strength of the rim for weight reduction and cost saving purposes.
