In case there is a question of the AGC levers working with other calipers, I’m using AGC 250 levers with Dura Ace BL-7400 calipers. I think they work great.

Side note: My levers did have the goofy screwed in cable housing end which I drilled out and replaced with a conventional cable housing. Not quite sure of the original intent of this contraption. Maybe it was supposed to make new cable housing installs easier.
