Derailer Adjustment (Sheldon Brown's explanation)
From what it looks like, it's a matter of setting the bike on the large-large (as in the biggest sprockets? highest gears?) combination without going through the rear derailleur, and making sure there's a full single link (~1 inch) overlap? Not sure if I'm missing anything.
I've never removed chain links before, so I just want to be sure before buying the chain tool and setting on a path to certain doom. I do like the idea of a master link, of which I've never heard of before.
Any advice would be appreciated, thanks.
