Interesting that you mention needing a longer stem. I have two genuine powers but needed a third for my commuter so bought one of these.
I noticed that the rails don't extend as far forward as the genuine versions and I could only just get it positioned back far enough. Not bad otherwise though.
i never tryed the original but you are right about the short rail of this copy i put mine as much back as possible, i read that the power is good for an aggressive position and maybe put me more forward or at least this is my conclusion to why a think i need a longer stem now.
