Abstract
A shaft for an indoor bandy stick, comprising a hollow tube. The tube has a substantially circular bottom end which turns elliptical when progressing upwards while the tube expands conically. The ellipse has a major axis (a) which at its maximum is at least about 15%, preferably about 30% longer than its minor axis and the conicity is such that the diameter of the ellipse parallel to the major axis (a) increases at least about 30%, preferably about 50% or more and the diameter parallel to the minor axis (b) increases 0-30%.
