If you want a carbon bike for the long run stick with one with a threaded bottom bracket and not pressfit.

If you are ok with rim brakes you can get a Pinarello GAN with 105 for around 2300 or disk at 2500.

Specialized also makes carbon bikes with threaded bottom brackets.

Also consider a lightweight steel bike.

As far as carbon bikes go, in that price range, the Pinarello is the best value.
