Abstract
A set of sprockets has a first sprocket with a greater diameter, at least one second sprocket with a smaller diameter and one or more spacer elements operatively arranged between, and in abutment with the sprockets. At least one of the aforementioned sprockets and spacer elements has engagement portions with a freewheel body of a hub of a bicycle rear wheel, the engagement portions defining an ideal circumference for coupling with the freewheel body. The first sprocket rests against the second sprocket, through at least one of the one or more spacer elements, at at least one first contact point arranged at a first radial distance with respect to a longitudinal rotation axis, and at least one second contact point arranged at a second radial distance from the longitudinal rotation axis. The radial distance between the first contact point and the second contact point is at least equal to ⅓ of the radial extension between the circumference and a radially outer end of the second sprocket.
