Eeee, a multi-quote reply, everybody loves these
I did, once bitten...
All done yesterday, including a new hanger and a different wheel (that's been working fine elsewhere).
Not a shadow, no, but I think you have to be right with the friction issue as Cheesy mentioned earlier too.
What put me off that idea is that I can get the top three/four or bottom three/four sprockets shifting smoothly, but the difference between the adjustment is 16 clicks, so two & a half full turns! This has got me chasing the bent/alignment side of things, plus the original hanger was one I'd straightened so initially wasn't 100% on that. New hangers made no odds though, tried both an OEM (crap) and a BETD.
However I've lengthened the last loop anyway (no better) and stripped the shifter which does seem to be snapping very strongly into place. So it has to be cable drag or the mech and the mech feels strong & smooth.
So I've employed an assistant to pedal/shift whilst I apply the gentlest pressure to the mech, to assist the spring and guess what? It seems to be doing the trick!
So the simplest solution, as always seems to be the correct one. In the old cables this would make sense (hence the change), not sure why I'd have drag in brand new cables though :? Nice stuff too:

The last open section does touch the chainstay, but pretty sure it's not enough to cause any trouble and wouldn't differ between gears anyway
So - Bullet tensioner?
Chasing a bit more info then I might have to own up to what I think I've done wrong...
Thanks for all the ideas so far

biglev":fdvixygh said:Yeah what the big cheese said plus:
Check chain alignment
Is the bottom bracket axel the right lengh to give a good chain line
is the hanger bent (or nto tight if its replacable)
Is the rear axel bent affecting alignment
cheers

Reluctant":fdvixygh said:That's a Shadow type rear mech, right? The cable goes "in front" of the pinch bolt as you look at it from the drive side. Ummmm - check that the last loop of outer is long enough to allow free movement, but not too long. All the parts you're using should be compatible, so it's most likely an excess friction/routing type issue. Good luck!
