Bar end shifting question
I just bought some used bar end shifters, 10 speed DA. I've never installed these before, just used them on bikes already built. I've decided I don't need them, and plan to sell them. Before I do, I want to be sure they work properly. On the shifter that is indexed, when it is not connected to a cable under tension, should there be play in the shifter at each stop? (I already have that one set to indexed, not friction). Also, they came attached to some aero extensions, what is the best way to remove them, they seem to be in there quite firmly. Thanks for any help.
