Firstly, there' s only 1 and it's size XL (21")
Secondly, it's the 2008 Model with v-brakes and not discs.
Even so, this is a great bike for £400 - a proper mountain bike which can handle the knocks without falling to pieces. If, like me, you have gone off disc brakes then the v's are a bonus..
For info - a 2009 version is around £650 and a 2010 version around £800
