the Trek Madone 2.1 is nice, but is also more expensive, 1200 euro, mainly because of the Shimano 105 drivetrain, the Giant is 1000 (but dollars), same for the Specialized, the Scott speedster 30 looks good too it is a give and take situation, we have been discussing on other threads how bike manufacturers throw in a great combination of accessories in every bike, so one bike will be better in a certain thing but save money on another thing, there are no two equal bikes for a given price, geometries are different in these bikes, you may need to test ride a couple of them before making a decision, finally, you are not stuck with what you buy, you can always upgrade accessories and wheels, etc. but that is recommended after you do some serious riding and you get to know better the equipment,
of the Ridley's, the Tempo Race because the other one has a triple chainring (written in the specs, but pictured with a double crankset) the Felt drivetrain is not straightforward 105, they refer to some parts as Microshifting, not sure what they mean by that, first things first, frame size ! how tall are you ?
