Specialized aluminium, single-bolt aluminium saddle-post from 2009. 30,9mm by 350mm, c 15mm off-set. 270g.
This ‘post is in good functional condition. Heads and threads are clean, no Zorro marks, minimal oxidation. The major flaw may be a feature, depending on your affinity for 1970s-late styling: the anodization is faded in a graduated manner, depending on exposure to light, of course. See photo for a close-up to determine for yourself =)
