This is an SR Royal 2- seatpost, Sake Ringyo’s interpretation of the 2-bolt, micro adjustable design. This post has a 27.2mm diameter. It is 200mm long with about 140mm of usable length (mid saddle rail clamp to minimum insertion line). The quill is straight and all threading and mounting surfaces are in nice condition. There is some light cosmetic wear. I have uploaded large photos. Please take a look and ask if something is unclear. Thanks!
