I have been considering an IGH. I want a drivetrain that's simple and easy to keep clean.
I might not ever convert a 2x9 into a 1x9. If I could just yank off the front der. and hit the road I would do it.
Unfortunately it seems like I need to add 2-3 special parts to compensate for the missing F.D.
That's not my idea of simplification...I might make sense on a new build or rebuild.
EDIT: Metricoclock seems to have pulled it off without any special gadgets.
