我在测量车架尺寸网站测的时候搞不懂臂长是哪里到哪里 原文是 Arm:（臂长） Continue to hold the cylindrical object and extend your arm in front of you, holding your arm parallel to the ground. Try not to allow your shoulder to come forward. Make sure that the object in your hand is perpendicular to your arm. Locate the Pivot of the arm to shoulder point and ～～～～～～～～～～～～～～ measure from this point to the center of the object, which should fall in line with your knuckles. Measure both arms and average the measurements. 问题是Locate the Pivot of the arm 这要怎麽看，中心点或旁边？ 另外肘长有一样的疑问 Forearm （肘长） Hold a cylindrical object (a magic marker is ideal) in your fist. Lower your arm so that it is to your side, and extend your forearm in ahead of you. Keep the object in your hand perpendicular to your forearm, and measure from the center of the object, which should fall in line with your knuckles, to the boney protrusion at your elbow pivot. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 这the boney protrusion at your elbow pivot又是指哪里？ 我摸不太出来，随便量 误差有2、3公分 --
