The Ergons are also adjustable and tilt back.I actually did see these Ergons and many others, but I needed to shift my weight back, not forward.
These other, extremely ugly bars you post, look nothing like mine.
My extension are pointing back, towards the seat and actually allow me to lean back so far that my shoulders are behind my hips and still have a comfortable grip.
I originally thought to put a different set of handlebars on, but that would require me to re place the brake and shift cables as they were too short. Not to mention the considerable work of re mounting the grips brakes and shifters and other mounts on the bars. On the other hand my bar ends took a total of 15 min and look absolutely beautiful, (I have received many complements and imitators.)
