It's octalink, yeh. Hmmm, more hassle! Are road and mtb bb's interchangable?
Would it be worth trying a different derailleur? I had no trouble shifting when the crankset/bb was on my mtb, albeit with a mtb derailleur and shifters. There are some '06 model campag triples going cheap. And they're 31.8 band-on's so with a shim (my seatube is 28.6) would it make the starting position further out? Or is that accounted for in the derailleur design? Thanks for all your advice, I didn't even consider bb length!
Edit - Reading through shimano technical documents it seems the mountain bike stuff I have has an "applicaple chainline" of 50mm and the road 45mm which would account for the problems I'm having. Anyone know the campag chainline? It's definitely looking like a new bb will be needed...
