I read your post, so you don't need to be snidey. If I don't agree with it doesn't mean I didn't comprehend it. I'm sure it's a topic that's been done to death, so other results will no doubt be available, but when Cycling News tested a 2013 bike with a 2023 bike, they found gains on the flat, but very few going uphill. Is that the answer for why climbing speeds have gone through the roof?
