This is the first time I take this route. I am on my endurance road bike with about 20 lbs of goods on the rack. My lowest gear is 34/32. I can't get the top the hill. I make it about 3/4 of the hill. I simply run out of air.

Let's say I am on a touring bike that's 10 lbs heavier. And the lowest gear is 26/34. Will I do any better?
