Why did you change it, I think mine needs changed as well. I get a sore neck, and I know the reach is too far for comfortable (often using tips of fingers)
I just looked, mine is 100MM in length, 31.8 wide or whatever it is. I looked at flipping it, but flipping it makes the handlebars lower so its already as high as it can go, and there is no room for spacers so they are at their max height. Height is actually fine, I think they need to be closer and think maybe 80mm might be better for me as well
