Front derailluer issue...
I have a Bianchi Giro with a 105 triple. The problem I have is with the middle ring. When shifting up from the small, or down from the large I get chain rub. It doesnt matter what cog I am in. To alleviate this I have to push the left shifter, it moves the derailluer, I hear an audible click and the chain rubs no more.
According to Zinns book this is not feathering as the book indicates you dont have that ability with a triple.
This a new issue that just started. Any thoughts on how to rectify this?
