Looking at their site the bike is a lightweight (and I reckon it'll come in around the < 11kg mark) fast hardtail XC bike. It's designed t climb and ride fast on singletrack etc. The geometry looks pretty aggressive,with a slammed front end (short headtube, low stack) so you'll be over the bars and paggering it. It's well equipped, with XT gearing (whether it's the full gearset is always in doubt) but the fork and wheelset are quality lightweight items. The very light frame is a bonus, as it's made by Kinesis apparently.
What do you want it to do? If you want to ride smoothish trails fast, then it'll do it very well. If you want to ride really technical trails it'll probably be a bit nervous, and if you are a novice it'll be a bit uncompromising at first wherever you ride it, but you'll have a blast getting to know it.
If it's what you want, then it's a bit of a bargain. In fact, it's a helluva bargain. I'd buy it.
It'll come mostly built up anyway, and there's nothing on a modern bike that needs more than a bit of know-how and the right tools.
