And yes, I used to run 2x9 (39/53 x 11-25) because a long lime ago, it was easy and cheap and then went to 1x9 (55x11-34) because cheap but still missing something and final a moved to 1x10 and 1x11 as my race bike (not in picture) because prices have come down as people move to 12s and electronic.
