At one time, cyclists tried to avoid using large stars, believing that they could save on the weight of the bike, and thereby increase their speed, albeit very, very little. However, Professor Stuart Burgess conducted research, and it turned out that with the same gear ratio, small stars are less efficient. Ceramic Speed recently also conducted research, and confirmed Burgess's findings. About how the size of the star affects the efficiency of the transmission, as well as its resource, in our issue.
