^^^This.
If it's ever a problem, I will find a way to deal with it. I doubt it will be.
This is theoretically a much bigger issue than it is in reality. This seems to happen a lot online.
I will dutifully report back in if I ever hit the derailleur on anything during the normal course of riding.
PS. 65r, your 20 (or whatever the Phillips equivalent is) rocks hard, always has, definitely an inspiration and fantastic build.
