Two things I really wish would come back into production - this cable, and high flange road hubs. I used to say freewheels, but IRD is doing a good job.
Anyhow, I know Velo Orange doesn't have any - I recently suggested that they do find a source of this stuff. However, today I was at Proteus bicycles in College Park, MD, and I asked Jill Dimauro if they had any of this sort of thing rolling around the bottom of the hammer drawer somewhere. She said, no she didn't, but she actually used to carry it, that Mel Pinto, of Mel Pinto imports has a source, etc, and I might as well talk to him.
So I'll see what happens there.
