Boltbreaker, that is a particularly interesting frame. It also probably has the longest head tube that I've ever seen, what frame size is it?
The shifter position seems particularly awkward to use, but you clearly are comfortable with using it and will keep it there.
fascinating bike
have you ever considered those drivetrain covers, to keep everything nice and clean? I understand they do have some contact with the chain, and some people dislike the sound.
