Hi all
Got a bit of a problem with my Campy Chorus rear derailleur. Basically, what I would describe it as is as if the cable isn't pulling back (down) the cassette enough.
On either end of the cassette it's fine, but across the middle, if I shift up (toward the biggest cog), it tends to overshift a small amount, and I have to manually push it back down one click. It's like there's not enough tension on the cable .. though it shifts down (towards smallest cog) fine.
Thought for a while it was sticky cables, but they've been changed. Have had it into a couple of OK bike shops, and they can't see anything wrong with the derailleur itself.
Any ideas? Anyone know anything about the tension spring in the rear derailleur .... could that be not doing its job for any reason?
Thanks in advance.
