How are Forged Wheels made?
Forging allows for wheels to be made in 1, 2 or 3 pieces. They start as a solid block of billet aluminum, which then has heat and pressure applied until it forms the shape of a wheel. This makes forged wheels 25-30% lighter than cast wheels. The forging process allows for more strength with less materials, which means additional room for things like larger brake components.
1 piece wheels, also called “monoblock” wheels, are all formed from one piece at the same time.
For 2-piece wheels, the center piece and spokes are manufactured separately from the rim.
3-piece wheels are constructed of a center piece, an outer barrel, and an inner barrel. They allow for even greater flexibility of materials than 2-piece wheels, since different parts can be forged, spun or cast.
