I wanted a light carbon bar for road riding.
I think the carbon does help mute the road vibrations on long rides, and the shape is a very good compromise between a classic bar with a long flat area and a ergo bar that lets me get my hands up in the hooks easy.
I have large hands and this bar works well for me.
Also, I stayed with my normal 42 c-c width measured at the ends. This bar is a bit narrower at the hoods, but I like the feel.
Used this bar to build up a new frame from scratch. I found the drop position so much more comfortable than the bars on my other (now for travel) bike that I bought a second pair and swapped them to the EC90 SLX. Just spent four weeks in Europe riding with them and can confirm the drop position is super comfortable.
