I own a Trek Domane SL6 but upgraded with Ultegra Di2, Dura Ace cassette, pedals and Bontrager RSL 37 wheels with superlight Rene Herse tires and though I haven't weighed it, it feels like it is over 20 pounds. Basically the frame is heavy for a carbon bike but I am willing to compromise because the bike is so comfortable.

What I like about the bike is the versatility. Yesterday I rode the bike with 650 x 42 on some gravel and the day before that on 700 x 37. Days before that I was on 28 mm tires on pavement. It really is an all rounder.

There are so many good bikes in your price range that what ever you choose, it will be a good one.
