Sorry I did not read all the comments. However, the video totally misses the point for me... if I could put out 200W all day everyday with 25kg, I wouldn't worry about bike weight. However, I have much less power that is also very affected by heat. Saving base bike weight can be the difference is suffering levels up hills, to being able to keep up with friends and to even attempt a ride. It can also mean the ability to carry more food, water or extra individual component weight for greater comfort.
