My initial lack of riding out of shapeness has now devolved into me having no energy (feels like I have mono, which you can't get twice) and my knee problems have come back. It has really discouraged me from riding. So much so, that I haven't even finished building my road bike. It's all a bit of a downer. So, to cheer everyone up, I'm going to give my short review of Dura-Ace 9000 mechanical.
