三、安装步骤Assembly Steps #
1、升降鞍座开关厂家默认安装在车把左边箭头位置，如下图（1）。安装时升降鞍座开关线在前刹车线后面，如下图（2）。也可以根据你的使用习惯安装在你觉得合适的地方，安装方法可以参考以下第2、到第3、步骤。By default, the dropper seatpost lever is installed on the left side of the handlebar at the position indicated by the arrow in image (1). When installing, ensure the dropper lever cable is positioned behind the front brake cable, as shown in image (2). You may also install it in a location that best suits your riding preferences; refer to steps 2 and 3 below for further guidance.
2、松开升降鞍座开关螺丝，放置在安装处，如图（1）。安装在左边车把位置时升降鞍座开关在油门线后面，如图（2）。Loosen the dropper seatpost lever screw and place it in the mounting position, as shown in image (1). When installing on the left side of the handlebar, position the dropper lever behind the throttle cable, as shown in image (2).
3、按箭头方向锁紧升降鞍座开关螺丝，锁紧扭矩为3N.m 。Tighten the dropper seatpost lever screw in the direction of the arrow, with a torque of 3 N·m.
4、安装完成后和油门开关没有干涉，（按压油门开关不会碰到升降鞍座开关）。如有干涉需要再次调整角度。After Assembly, ensure there is no interference with the thumb throttle (pressing the thumb throttle should not touch the dropper seatpost lever). If there is any interference, adjust the angle again.
