Weird round chainstay cable stop, special ferrule needed?
I recently got a nice old bike given to me. I decided to upgrade it a bit. I had a spare 9-speed Tiagra brifter, so I decided to install a 9-speed drivetrain. It's shifting great on the workstand, and it's shifting great most of the time, but sometimes it seems to hang between gears.
I suspect that the ferrule I'm using for the chainstay cable stop for the rear deraileur cable is the problem - or at least, part of the problem. The cable stop is weird, I don't remember seeing that kind before - instead of being the usual tube that receives the cable housing, it's a brazed-on metal sphere with a hole going through it.
Now, when I got the bike, there were two ferrules on the rear derailleur cable housing. A normal ferrule which was inserted into another kind of ferrule - and the outer ferrule is not in good shape. The photo doesn't do it glory...
Anyway, that outer ferrule has seen better days, and it doesn't seem to be fitting very well in the spherical cable stop.
So, I was wondering, does this two-ferrule arrangement seem like a good thing to do? Should I go looking for a replacement outer ferrule, or is there a better way to mate the rear derailleur cable housing to the weird cable stop?
