Which Groupset?

Campagnolo state you should use 3 clicks to change front ring. You can then click back once, to trim things if needed. If you tend to shift front from the middle of the cassette or beyond you wont need to trim. I tend to shift chainring early in preparation for a approaching climb, yet still dont use the trim click.

My front mech clears the chain by a whisker in the big ring, little sprocket position. This achieved via cable adjusters. It is the limited in the inner most position, via the limiter bolt. To clear the chain by a whisker on the other side. When in little ring, big sprocket position. Works for me*

(*when my silly cassette behaves)

Ok good to know, I didn't really think it through, but that all makes sense. I will try to perfect my technique.

I will say this about Athena: I used to find gears annoying, but a good groupset like this makes the bike a joy to ride
