In my usual tinkering, I often swap front derailleurs on bikes for myself and less-technically inclined friends. In order to prevent extra fiddling with the derailleur, is there an easy way to make sure the high-low adjustment screws are "centered" (allowing maximum adjustment) before mounting? It's always frustrating to get the derailleur on to begin adjusting the stop only to discover there's no enough adjustment room one way or the other.
Just wondering if anybody has a quick way to deal with this. Thanks.
