There's some good contenders at Evans cycles from pinnacle and specialized, but that boardman with the carbon fork (mentioned above) looks tough to beat for the cash.
The bizango mentioned is a great bike but it has a 1x11 drive chain, so if you want to ride fast on the flat or downhill on the flat , you might find yourself running out of gears. It's geared to be a mountain bike rather than a tarmak sprinter.
The boardman is 1x10 but I imagine the front ring is quite a bit bigger than on the bizango, allowing you to get more speed, rather to aid lower geared mountain bike set ups.
