Running out of cable is what it's doing, I should think. It wouldn't have been designed to pull a derailleur that far across the cassette.
There are some Shimano bar-end shifters that can operate as non-indexed friction shifters for 8/9-speed, I think, so you might find downtube friction levers with enough range.
But friction shifters with a 10-speed cassette is kind of perverse. And quite amusing. :)
friction works well exept the mentioned problems. I like it to, feels good to be able to microadjust.
but I have some DA downtube shifters heading my way as we speak. Wonder if it will help against autoshifting. And I really hope i can fit them in the suntour band on studs I have now. have anyone tried something similar?
