I lowered my handlebars yesterday 2 spacers to give it a try. Should've just tried one but the person who fitted me to the bike originally told me I could be at this handlebar height when I first bought the bike. But decided to keep the 5 spacers in the meantime to get adjusted to the smaller more aggressive frame. I've been slowly lowering it and was down to 2 left and just decided to go all the way and remove all spacers and leave only a big 30mm spacer.
I went out for a short ride to give it a go and immediately noticed that I was rocking my bike a bit more. I felt like my legs were extending a lot more than they were before and had to focus to not rock the bike. Did a very short ride at a higher effort and when I focused on not tilting the bike, I could do it but it's something I had to focus on and not just naturally do. Other than that I didn't feel any discomfort for now but we'll see how it goes later. Just felt a lot more aggressive than before. Is this something I have to get used to? Or maybe I'm not ready for that position? Or maybe I'm too fat for this sport?
