A variator is disclosed comprising first and second races disposed for rotation about a variator axis, at least one rolling element disposed in a cavity between the races. In a drive configuration, drive is transmitted between the races and the or each rolling element; and in a neutral configuration, the or each 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 or each 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 or each rolling element to a position in which it makes contact with both of the races. |
