So no upcoming IGH's on the horizon?

No possibility of me going to Taiwan in the foreseeable future, let alone during the bike show period.

I wouldn't call it OCD. Why? Because efficiency matters. I can feel the difference between 80, 85 and 90% between 1 IGH and another. Everyone knows the pros and cons of IGH vs derailleurs vs single. I must have IGH.

True, even the gold standard Rolhoff graphline isn't flat. But notice it's the most steady among the lot. It's as steady as IGHs go at the present.

NB: The first of 3 graphs in that webpage of efficiency measurements can be ignored. The writer claimed that he improved the test to account to obtain steady averages. Therefore only 2nd and 3rd graphs should are valid.
