My apologies for overlooking the information that you had provided. You are correct. I just checked and there is a 7 speed brifter option using RX and RSX 100 series. This throws another wrench in my situation now..lol. I now have two options to go with since have two complete group sets. one Shimano Tri-color 7 speed and the other with Campy Veloce 8 speed after a cold set.
