9 speed cassette, deore rear mech & shifter.
The basic problem is that the shifter seems to go through all it's travel by the time I've gone half way up the cassette. I've checked the cable, it's doesn't appear to be snagging anywhere, re-adjusted derailleur limit screws, re-tensioned cable, you name it, as much as my basic bike mechanic skills allow me.......
I'm probably missing something blindingly obvious or doing something fundamentally wrong, but it's got me stumped. It's just as if there aren't enough clicks in the shifter.
Any thoughts please?
