Buy a scott. Dunno why I just like 'em. or try and get hold of an old orange p7 (think that's the one) my mates dad has one and seriously it's the lightest thing in the world, would put tarty Adams Czar to shame. or you can do what I done and buy a cheap second hand jump bike (like I did) and just wack the saddle in the air and buy a new cassette to give you more range throught the gears. or you could not buy a Carrera as I wouldn't trust halfords to make toast, let alone a bike. or go to Wight Mountain and see if they have anything in the second hand part of the shop, I might be able to swing you a bargain.
