Quite Fond(riest) of this frame

@190-215GPa Dave, the ferrules arrived today and I took them straight to the Pinarello garage. Thanks so much for sending them, it was very kind and your note made my day!

However, they aren't the correct type. It is my fault. After trying not to weep uncontrollably and having now consoled myself, I have discovered that there are two forms of these different Cinelli diver's helmet braze-ons. For anyone who may have this issue in the future, I've attached a handy image.

Of course, mine is the 5mm internal diameter type, and of course, these are as rare as it gets. I found a few photos (attached) to show the exact form of ferrule needed - notice the shape is different from the others, with a shorter insert and slight curve at the end.

I may have found one in Germany, but until the seller confirms the diameter, the bike remains with Pinarello.
