These wheels have an overall diameter of 72mm and a width of 32mm. The offset center gives you 8mm from mounting surface to edge on one side and 16mm on the other which allows you to change your track-width by flipping the wheel. The 14mm bore provides a centering mechanism on hubs that have a 14mm protrusion.
