This bike has definitely been a black hole for me! I've tweaked my front derailleur a little bit more. Occasionally, when downshifting, the chain will fall in between the two chainrings and actually get stuck between the underside of the large chainring's rivets and the teeth of the smaller chain ring.
I'm also considering switching the drivetrain to a 1x8 using a 52t chainring and a 11-32t cassette. Hopefully I'm using bikecalc.com correctly, but it looks like with this combination, I actually extend my gear inches in both directions. Is there anything else I should be considering?
