So I went through a bunch of trouble to get my front derailleur to shift properly between the large and middle rings. I got so focused on fixing the problem that I never bothered to pause and consider whether it mattered.
Today the epiphany hit me that I never use my large ring--ever. I use the middle ring on the intermediate trails and sometimes the small ring on the advanced trails. I replaced my outer chainring today with a Salsa Tooth Fairy bash guard, which is a pretty sweet component I must say. It replaced the outer chainring I bought about a week ago for $30 :| If only I had had said epiphany earlier.
