This is a camera mount that can be attached to bicycles and motorcycles. It's an easy-to-install type that can be fixed simply by tightening the head screw. Digital cameras and drive recorders can also be attached. The head part uses an alloy. It can be attached to bars with a diameter of approximately 17mm to 30mm. A separate tripod mount is required to use with GoPro. It has been stored in a private home. Thank you for your understanding. #Motorcycle #CameraMount
