Abstract
A variator comprises first and second races disposed for rotation about a variator axis and at least one rolling element disposed in a cavity between the races. In a drive configuration, drive is transmitted between the races and the at least one rolling element; and in a neutral configuration, the at least one rolling element and races are configured whereby the races can move independently of one another. In a method of operating the variator, the neutral configuration is obtained by moving the at least one rolling element to a position in which it ceases to make contact with at least one of the races. The drive configuration is obtained by moving the at least one rolling element to a position in which it makes contact with both of the races.
