Excellent Ritchey WCS seatpost. 350mm long. 27.2mm diameter . Bomber aluminium. Adjustable to suit any seat angle. Double clamp secures saddle rails. Some marks / scratches from use (see photos) but in very good condition overall. Works perfectly. Transfers showing signs of use and maybe too much polishing! Note that you can use this seatpost with a shim (typically a plastic USE, from a well known web cycle store - not provided) to fit any frame seat tube diameter... this is what I do where possible to stop risk of seat post seizing in frame... Selling due to now having bike with dedicated aero seat post and this just won't fit!
