Trimming the Gears?

Usually, the lefthand levers control the front derailleur and everyone has to trim the front derailleur at one time or another if you have a triple. It is just making minor adjustments to keep the derailleur from rubbing the chain when the chain line is at an angle.

Campy has infinite teeny adjustments while Shimano has the "half shift" clicking and is therefore limited to how much it can be trimmed. Having used Campy or barcons for years but just recently learned Shimano road STI shifting I can definitely state that Shimano has more of a learning curve. I'm with Emily on this one.

If you're having to "trim" the rear derailleur, it is out of adjustment.

Hey SK...I think that this might be what you tried to show me how to do at one point on our ride? Am I right?

We talked about cross-gearing when your chain is on big/big or little/little front to rear. No amount of derailleur trimming is going to work in this instance. However, the sound of your derailleur rubbing is a good indication that you either need to trim the front derailleur or "uncross" your gear selection. That sound is what alerted me to look at your chain on Sunday.
