Whilst riding recently the cable slipped from the clamp on the rear derailleur.
I'm attempting to affect repairs by re-clamping the cable. However by pulling the cable tight I have lost the bottom 2 gears. If I then slacken the cable just a small amount I gain the bottom gears again but lose the top gear. I can't seem to reach a balance.
This is the first time I've had to fit a cable to a derailleur, are there any tips? Am I potentially doing something wrong? Do I have to be in a certain gear before attempted to re-attach the cable to get the correct balance?
