You may want to look at the Kineses Crosslight 5T. It is meant to be an excellent frame and has a Tiagra groupset. The other components seem to be good too eg Mavic CPX22 wheels

Here are a couple of other nice options:

Cannondale CAADX5 - full 105 groupset and BB30 bottom bracket

Fuji Cross 2.0 - nice combination of 105 and Ultegra components
