My local bike shop ordered F1 dual disc Galfer lines for me. I heard him repeatedly say yes to their questions but they were too short on the top hose and the lowers were made for the stock steel tubing which I didn't want.
He couldn't do a return because black was a special order color. Anyway, I kept them and paid his cost. I eventually used all three hoses.
Moral of the story, have your measurements at hand when you call.
