The invention relates to a disk set arrangement with a driving disk set and a driven disk set for a chain-type CVT, wherein each disk set of said arrangement comprises two disks that are axially displaceable relative to one another on a shaft and a chain arrangement comprising thrust pieces that are active between said disks. The longitudinal axis of said thrust pieces runs parallel to the rotational axis of the shaft, and the frictional surfaces of the disks and the thrust pieces have a curvature determined by a radius and an eccentricity, wherein the eccentricity of the disk in the driving disk set is different to that of the driven disk set.
