Indysteel ...

Your dissertation on gears 101 was much appreciated by me ... even if it's not what the original post was asking! I can't wrap my head around the relationship between big and small rings, high and low gears, and easy vs. hard to pedal. I know which ones I like to use in which situations, but I am utterly unable to explain it to anyone else! Thanks for the explanation. I think I'll print it out and study it while examining my bike gears.
