Cinelli stem: stayer - of course that is what it is...
Stayer stems - with which I was completely unfamiliar until I found one in the shed. I must have run in the wrong crowd lol
I'm still a little confused as to whether these were intended for shops and team mechanics to test for exact size needed by individual riders, or to be used by individual riders and adjusted based upon other factors for a particular ride or race. Otherwise seems like extra weight rather than just getting the right specific length.
