Nope, no indexing, acts like a friction shifter. The upshift takes a ton of travel to to get the chain to move, I mean way over towards the stem, no "crispness" at all. Downshifts index, up no. Pulling the cable along the dt shifts about like brifter does, except with better feel(!). I will pull the cable and clean, see if that helps. The cables and housing are not the originals, 4yrs +- on them.

Drew, thanks for the links, I'll buy the parts while I can still get them, best to have some spares regardless.

"Is the rear derailleur of the same vintage as the shifters? Campy changed the derailleur's actuation ratio in 2001."

yes, same year

My interpretation of post #1 is that the OP is having indexing problems while downshifting because the statment is: "does not index when climbing the cassette". This sounds to me as if he means the problem is when shifting toward bigger cogs, though this is actually downshifting.

correct

If this is correct the problem may be with the shifters, or possibly a bent derailleur hanger, or a problem with cable routing at the rear derailleur. A problem that I've seen recently was caused by the pinch bolt washer tab pushed up against the cable effectively changing the actuation ratio slightly.

interesting.

always appreciative of input,
Brian
