A cable routing system of a bicycle, including a stem having a receiving space and an engaging hole communicating with the receiving space, a frame, a fork, an expander, and at least one cable. A head tube of the frame has a top portion having an upper mounting hole and a bottom portion having a lower mounting hole. The fork sequentially passes through the lower mounting hole, the upper mounting hole, and the engaging hole to be connected to the stem. The expander is disposed in a steering tube of the fork and has at least one cable passage communicating with the receiving space and the engaging hole. The cable extends into the steering tube from outside by passing through the receiving space and the cable passage. An end of the cable is connected to a bicycle controller, and another end thereof is connected to a bicycle component.

A straddle vehicle includes: a shift drum that makes a shift change of a transmission including a plurality of gear trains; a transmission case enclosing the shift drum, the transmission case including a side wall portion provided with an insertion hole into which an end portion of the shift drum is inserted; and an actuator unit secured to an outer surface of the side wall portion, the actuator unit including a drive shaft that outputs drive power to rotate the shift drum, the drive shaft having the same rotational axis as the shift drum and being connected to the shift drum on the rotational axis.
