Thank you for answering all my questions Cyccomute. I think I have a plan of action now and a recipe to follow. Will look for an 11/34.
One last thing, what is the difference in the crank length option? 170vs 175? Seems like splitting hairs.

I took my bike out to a steep hill yesterday and tried going up un loaded with my existing gearing. Yes, I will need low gears that is for sure.

Edit** on looking for a 11-34 sprocket I don't see too much….except this crazy pricey one

Does it make sense to convert to 8 speed while I am at it?
