I am looking to upgrade from my old Trek 1000 to a much nicer bike. I am a runner trying to covert to biking to save my knees. I am 40 something but ride hard and want something responsive but not painful. I am looking to spend $2000 or less. I have looked at the Trek 5000, Cdale CAAD8 R1000 and Giant TCR comp 2. Does anyone have some insight on these bikes? Are there any other bikes I should look at? Thanks

Have you considered something with a more of an upright geometry such as the Trek Pilot?

The Giant comp's are nice (I'm on an '05 TCR comp 1) - I'd look at the OCR line as well.

I like the Treks too (actually there are d@mn few bikes I don't like).
