the indexing is what I would call excellent. Some subjectivity is
involved. It doesn't help that all Ergos have some play from new: partly
deliberate (the overshifting feature) when shifting to larger sprockets,
and partly some slop in the works when shifting to smaller sprockets.
This makes *perfect* and noise-free setup tricky even with properly
matched stuff.
Again, I believe that there is much variability caused by the
installation of the system. Quality of cables and housing, lengths or
loops of housing and how tight those loops are, chainline, chain
length, chain brand, and length of chainstays all cause shifting
variability. Cassette range is a factor too. Shifts for an 11/23
seem more difficult than those for a 13/29.
Define a perfect shift. When you move a lever or push a button, you
hear a click and there is a positive shift without chain noise during
and after the shift. People are more tolerant of a poor shift to a
smaller cog than to a larger cog. Is a perfect shift when the click
and shift happen at the same time?
I've had the opportunity to setup systems for singles and tandems with
Ergo 9 and 10. I can get mixes to work. Sometimes the range of error
in adjustment is very fine. Too fine for an average owner. Examples:
My hookups of Campy 10 with Hubub hookup to XT/XTR rear derailleurs is
positive. The cable will need to be readjusted when the bend sets in.
SHIMANO CASSETTES: I got an early 10 sp Shimano wheel in 2004 and
put it briefly into my Campy post 2001 x 10 sp bike. It seemed to
work ok in stand. This year, I bought one of the first 12/27 Shimano
cassettes for my Record 2003 system. I think it ideal cassette with
my 50/34. I could not make the cassette work to my standard and
promptly sold it. Later, I read that post 2001 shifters and a pre
2001 derailleur will shift the Shimano shifting perfectly. I bought
the cassette again and installed it using an 8sp Record rear
derailleur. It works aOK. I then put my Shimano 10 sp wheel into my
wife's post 2001 matched bicycle and it worked fine too! I don't
know.
My '99 Daytona 9 shifters with 2003 Centaur derailleur shift my tandem
perfectly.
All the 10 sp Ergo systems seem to shift Shimano 9 fine, especially
with Shimano HG chain.
