Perhaps in the B mode with the angled parallelogram it would index well. In the A mode the design geometry is lacking compared to the NR and SR.
Yes - my FD is braze on. I don't think the 1st gen Chorus RDs were designed for indexing, but they do shift well in the "B" position, where they are actually the first Campy slant parallelogram unit (I think).
