Static bowl is usually made of wood, but it also has plastic items, which serve to divide the slots with numbers. The bowl is the outer part of the wheel and it includes ball track, lower back track, spindle and canoe stops. An average bowl has 32 inches in diameter.

The wheelhead has 20 inches in diameter and it sticks to the spindle. At the top of the wheelhead there is a cone which directs the ball and a turret which hide the part of the inner mechanism. Also this part of wheel contains pocket with marked numbers. There can be 37 or 38 pockets depending on the layout.
