RD7700 is a rear derailer model, not a shiftlever model. Maybe you have
the BS77 shifters?
When you say 9 & 8 speed, what do you mean. Are you referring to the fact
that the BS77 shifters are intended to be compatible with an RD7700 rear
derailer in a nine speed application, or an RD7400 rear derailer in an
eight speed application? Or are you referring to the RD7700 derailer being
applicable for both 8sp and 9sp setups? Or are you saying you do cassette
swaps or wheel swaps and use both 8sp and 9sp cassettes on this bike with
the same rear der and shifters?

OK so you are in the smallest cog. Lets call that position 9. You click
from position 9 to 8, and the derailer shifts. You click from 8 to 7, and
it works. You click from 7 to 6 and it works. Now you are in the middle,
and 6 to 5 is not going to work. What doesn't work? You said 'skips two
clicks'. You mean that the shifter has no clicks, and acts like a friction
shifter from 6 to 5, and continues to move like a friction shifter from 5
to 4. Those two clicks are 'skipped' in the shifter. Then from 4 to 3,
the clicks reappear, and click properly all the way to position 1. Is this
what you are describing?
Or do you mean the shifter does click from 6 to 5 and from 5 to 4, but
those two gears are skipping when you pedal in those gears? Is that what
you are describing?
