I have no idea what they used to be like, but my comments were towards the 2010 and newer stuff since that's what you would get if you bought something today. For some reason they are still advertised as "identical except for weight" even on websites like Competitive Cyclist. Oh well. I just wanted people to know there are *now* structural differences between Rival, Force, and Red front derailleurs. Being informed is better than not, right?
I'm going to take some pictures when I get home to show the structural differences between the three.
