Width, geometry, colors, strength
weight, but not by muchOverall Review: The atlas are an excellent bar. They come in at the perfect width and they feel great. The low rise is perfect for riders who like a low setup, and it gives that aggressive, racy feel. It comes in a bunch of great colors so you can match it to pretty much any build and they seem to hold up well in crashes. They are definitely heavier than some competition but they look better than most of them.
