Hi to everyone.

Which is the difference?
Pretty simple: 1-piece wheels are just that, rim and center cast or forged as one integral piece. 2-piece wheels have rims fabricated seperately from the centers and then fastened together, usually with bolts. 3-piece wheels take this a step further and split the rim in 2 pieces so offsets and widths can be easily varied. A properly done 1 piece wheel is theoretically technically superior, but there are lots of variables. The latter two are often done to easily adapt a wheel design for multiple fitments, but it is not the purest way to do it.
