[peterj]

Hi, i currently have this bike:

http://www.evanscycles.com/products/genesis/core-00-2009-mountain-bike-ec017148

everything has been upgraded apart from the drive train, for the drive train i want i need a new bb so the question is will this fit my bike?

the only question would be the front derailleur; it will probably need a larger than Ø28.6 band.

everything else should work ok.

Now the real question: why? You will have a very very hard time telling the difference between what you have now and the new group. I would consider changing out the RD, cassette and rear shifter only. Many people that do particularly rough riding have switched away from the external bearing BB's because of fragility and poor sealing protection of the bearings.
