This is the REC-MOUNTS lower adapter long type R [GP-K400ALR]. I purchased it new on Amazon in 2024 and used it to attach a CATEYE light, but I'm no longer using it, so I'm selling it. It shows signs of use. The items for sale are the main body and two screws. There is no packaging or instruction manual. Please refrain from purchasing if you are looking for a pristine item, as this is a used item. #GoPro #adapter #rec-mounts #lower #CATEYE #ampp #volt #randonnee #cycling #pottering #roadbike #crossbike #touring #light
