As I mentioned in another recent thread I've just bought my first wrecked up 'classic' and am working on fixing it up. I've come to replacing the front derailleur gear cable as the old one was stretched, rusty, frayed and having no affect on changing chainrings.
I've got 2 problems I'd appreciate a few pointers on if possible, I've done some research but all the pics I pull up tend to be of newer setups:
1. I'm not sure if I'm setting everything up correctly when tensioning the cables. I'm currently putting the (downtube) lever right forward, parallel with the tube, with the chain on the smaller inside chainring. I'm then tightening the cable clamp on the derailleur with the cable pulled hand taught. So then when I pull the shift lever up towards me the cable should tension and the derailleur should be pulled outwards towards to larger chainring. Is this all correct so far?
2. The next problem is that when I put any tension on the cable, no amount of tightening of the clamp will stop the cable slipping. Comparing the pic below of my derailleur to similar ones online (see here), it looks to me the clamp is bent out of position. In a word, is my derailleur done for?! I can't get any leverage from the levers to pull the derailleur out towards the large ring, the cable just slips, is this likely to be the cause?
