I recently bought a mixed 8 speed groupset: Record Titanium levers, Chorus calipers, Chorus front mech and Athena rear: it came off one bike, so I assume it all worked together.
However, the front mech only just shifts onto "the big dog" with the adjuster screwed right out (ie not limiting its movement at all): it will not physically move further out.
When in first, second and (to a lesser extent) third there is a distinct clicking from the rear mech caused by the chain clicking onto the lower jockey wheel: it initially arrives there at too much of an angle to sit correctly.
It seems clear to my idiot self that the chainline is out and I need to bring the crankset inboard. What concerns me is that I have only swapped from early-90s Campag to mid-90s Campag and can't understand why it doesn't work: am I missing something obvious?
