I wasn't clear....
Bolt-on = bolt-on to the bracket that was brazed-on (or bonded, as the case may be) to your seat tube, aka. braze-on derailleur.
Braze-on derailleur is one of those terms that just doesn't compute in my head. After all, water bottle cages aren't usually referred to as 'braze-ons' nor are any other components that attached to 'brazed-on' frame fittings. Don't get me started on clipless pedals; you know, the ones you clip in to and out of.
