Campag 8 speed woes

Evening Dammit,

I think I have had a similar problem on a classic Raleigh racer that I had:

**1. Your rear down shifter is not for an eight speed. Does the leaver push further one stop when you are in you lowest/highest gear?

1. your gear cables need a look at. Re-tensioned or probably easier to get new gear cables.
   
   

OR

1. Potentially mis-alignment with the rear derailier.**
   
   
   

If when you put your foot down you suddenly change gear with a massive clunk then I reckon one of the above three points (or a mixture of above) is where to start.

Good luck...

Gilles.

PS - do you know if you can change your title once registered?
