This is the one with the shock running parallel to the seatstay isn’t it. If so I had the S-Works version. They were good in their day but the offset shock did make it feel like it was twisting slightly on compression and they were quite flexible – lots of lateral flex round the BB. I’m only 65kg and not much power so usually I don’t notice such things but this was pretty obvious.
I sold mine and bought the 2009 Epic Marathon which I still have. This is a huge step forward, and I love it, but compared to a more modern bike it feels pretty twitchy and flexy.
I wouldn’t touch the 2007 version unless it was mega cheap, there was nothing else about and I didn’t want to do anything more than fast XC (What it was designed for!)
