I have friends who use the Csixx chain guide. I am not impressed. Also I like how you blindly judge the E.13 without even looking at it. It's clear that you're just a hater, and we all know haters gonna' hate.
And if by "exactly the same in every way" you mean "it looks like one" then you are correct. But it also looks like a Kona, so it must be a Kona ripoff too right? Really the Aurum frame is functionally nothing like the Trek Session frame. It lacks ABP and Full Floater, the two main features that help the Session stand out from the crowd.
