The invention discloses a front fork vertical pipe and a front fork. The front fork vertical pipe comprises a pipe body and a reinforcing piece. The pipe body comprises a pipe body and an in-pipe space. The pipe body is provided with an inner pipe face and a wire outlet opening. The reinforcing piece comprises a ring part arranged along the inner edge of the wire outlet opening and two foot parts connected to the ring part. The loop part is provided with an inner ring edge facing the space in the pipe. And the inner ring edge is flush with the inner pipe surface. And the foot part extends into the space in the pipe from the ring part. Each foot has a distal end spaced from the inner tube face. The front fork comprises the front fork vertical pipe and two front fork arms which are respectively connected to the front fork vertical pipe. The wire rod is arranged in the space in the pipe, so that the wire rod is prevented from being exposed. The reinforcing piece reinforces the structural strength of the pipe body, so that the structural strength of the pipe body can be maintained at a certain degree or above.
