barretts, you've mentioned your setups before, and I agree 100% on how versatile the 39 tooth is. While I am intrigued by compact doubles, I really think I will always be a triple fan, especially as I can often have a pannier with stuff on a bike, and then also because I like you, find the middle chain ring to be so versatile for so much of my riding and not having cross chaining.

tks for the charts. Us gearing nerds find those neat.
