(Imagine this is a spooky mysterious voice you might hear in a dream or when you awake in the middle of the night ) "Come to the other side! Come to New Hampshire!"

Seriously, not knowing you or your wife's climbing abilities, let me recommend lower gearing. At least go to a 26T or 28T granny, but I'd also encourage a 30T or 32T bailout cog. I realize you are limited with a 5 speed freewheel, but trust me there are times when the grades in this region justifies a low-low gear.

Getting back to the build: Well done and I know your pain and frustrations! Having converted several vintage bikes which never imagined anything more than a half step double, the triple conversion can be very challenging. In the end you sorted it all out and learned so much along the way. Have fun in Northern Appalachia this summer!
