Which drivetrain are you running? One reason (one of the many) I like Dura Ace 7800 is the available gear indicator on the shift cable.
I suppose someone could mount this on a 7900 or 9000, but haven't tried it on my gf's bike.
The next simplest gear indicator is downtube shifters.
Someone on Google put them on a mountainbike, so I suppose it's possible.
