I started fiddling with my bike again (which is not a good idea for me) and I noticed that when I'm in the small/small combo (34x12), the chain rubs on the rear derailleur. Not that I would use that gear much, but I don't know if it has always been that way, or if I messed something up. The only thing I touched on the RD was the barrel adjuster.
In the pic, the bike is upside down, but even when it's right-side-up it still rubs a bit.
