I'm pretty sure I have one of these stems, and in the size you want. Whereabouts are you based though, as I'm not overly keen on posting/hope you could collect if you're local to me?
Hi, I have Cinelli 63s x40cms ctrs Hbars complete with Cinelli 1A stem x 100mmctrs.
Centre ferrule has slight scratching on front right (as veiwed from front)
These are both in good to V good condition.
