I bought a new derailleur, cassette, and hanger after a decent wreck. Shimano 105 set, 11 speed, 11-34 cassette. I've tried adjusting the shift cable barrel, H/L limit screws, and the screw that sets offset from big cog.
The derailleur hardly moves at all between the two lowest (biggest) gears and when I get to the highest (smallest) gear it doesn't always travel go far enough, and barely even touches the limit screw. I thought indicates the tension is too high, but if I loosen it any more it become sloppy and starts skipping.
The cable is older and has an tiny kink in it in the highest (biggest) gears when loose, should I start with a new cable? I've never worked on the cockpit of a road bike so I've been avoiding taking the bar tape off.
I'm not sure why the derailleur movement at the low end is so small, is that by design? Every other shift causes a noticeable chain-width-sized shift in the jockey wheel's horizontal position.
