Record Ergo's shifting two gears instead of one(2 posts)

Record Ergo's shifting two gears instead of onemaurizio

I converted my 9sp. record carbon ergos to 10sp and it works good, but not great. On some occasions, near the end of the cluster (11 or 12sp), on a downshift, it will go two gears down instead of one.
What gives?
Is the return spring on my rear dera. weak? Could my cable housing have a kink or resistance in it?
It performed flawless on 9sp. For the most part, the 10 is great too, just seems to drop two gears on occasion?
Anyone blast those internals with WD-40 every now and then to lubricate?
Ideas?

Probably just need to tweak the cable tension a bit. Try loosening the cable adjuster (lengthen the cable housing) a tiny bit. If that doesn't work, if it were me, I'd start over with the rear derailleur cable setup, as demonstated here:
