I can tell you that my wife goes up hills way easier and quicker than I do. She weighs 100 pounds less than me, and we’re on the same model bike. I go down quicker . I weigh about the same as you, but I’m old and trying to drop 20, which seems like a major hurdle. I’m guessing it will help me going up hills, if I can drop some weight. Probably not the scientific answer you’re looking for, but I’m guessing somebody will help with more helpful data.
