Ah, I'm learning so much... but still have far to go!

Eden, doe "cross chain" mean when you have the chain on a biggest/smallest combo? I think I know what you are describing in general -- when you shift, and the chain makes that *rubbing* noise?

OakLeaf, I did not know it was possible to shift 2-3 cogs at once! I will have to try it...

Lisa, my shifters are 2007 FD 105. In an effort to figure this out, I've tried pushing very, very hard, all at once, but my hands simply can't do it without steering into the bushes... and once I accidentally threw on my front brake in the effort!

This is very interesting. *Trimming* is something that never even crossed my mind!
