1. A transmission chain with links mutually coupled by rocker assemblies, which each comprise a first and a second elongated pin, of which the first pin rolls during operation with a curved longitudinal surface over an opposite longitudinal surface of the second pin, while in each rocker assembly the first pin is destined to cooperate in a force transferring way with an opposite cone pulley of a pair of pulley sheaves, and the first pin has a first dimension (b) in the longitudinal direction thereof, a second dimension (h) in a direction perpendicular to the longitudinal direction as well as to the running direction of the chain in which said pin is accommodated and a third dimension (d) cross-wise to the longitudinal direction and in the running direction, wherein for each value of the first dimension (b), as determined by the preferred width of the chain, the second and third dimensions (h) and (d) respectively, are chosen such that the respective ratio between the first dimension (b) and the second dimension (h) is less than or equal to approximately 4.1, and the ratio between the first dimension (b) and the third dimension (d) is less than or equal to approximately 8.2.
