The present invention provides a transmission system (12) comprising a first pulley (211) connected to an input (11) by a cable (40) such that movement of the input causes rotation of the first pulley. The first pulley comprises an annular recess (25) between a first side (17) of the first pulley and a second side (19) of the first pulley. The annular recess is adapted to receive the cable such that the cable is supported by the first pulley. The first pulley also comprises a pair of support surfaces (31) located in the annular recess, which are moveable in a lateral direction relative to the sides of the pulley between a spaced condition, wherein the first pulley is at a first diameter and the pair of support surfaces do not engage the cable, and a meshed condition, wherein the first pulley is at a second diameter and the pair of support surfaces support the cable, the second diameter being larger than the first diameter.
