[QUOTE=LauraB]I've had a Trek 7500 hybrid, and have been doing enough riding to finally upgrade to an actual road bike.
I've narrowed it down to two bikes, and am having a hard time deciding.

Hi LauraB - not a bad problem to have trying to decide between two great bikes.

I have a Trek 5000 and love it. Its the first bike I have ridden in 25 years and boy that carbon sure is light.

As far as pain goes I found I experienced a little shoulder neck pain but that with more riding my body became accustomed to the racing bike position and it disappeared.

Im sure you will have a great time which ever bike you decide to buy. Enjoy the freedom of the road.
