A crankset of a bicycle includes a chainring (10) having teeth (12) on an outer edge thereof, a spider (20) connected to the chainring (10), and a crank arm (30) connected to the spider (20). An offset (50) is formed between a center of rotation of the crank arm (30) and a center of the chainring (10), so that the chainring (10) has a longest force arm (16), which is a longest distance between the center of rotation of the crank arm (30) and the outer edge of the chainring (10) and a shortest force arm (18), which is a shortest distance between the center of rotation of the crank arm (30) and the outer edge of the chainring (10). An orientation angle is formed between the longest force arm (16) and the crank arm (30), and the orientation angle is in a range between 30 degrees and 150 degrees.
