Well, I searched the forums and couldn't quite come up with my answer so I guess I will pose it here to those with more experience than yours truly. I have been narrowing down my new bike choices and have considerably narrowed the field. The Felt FW35 has a carbon seatpost, but not stays, but is full 105, and is a double. Both the Trek 2.1WSD and the Specialized Dolce Elite have carbon seatstays and seatposts, but are Tiagra front derailer and shifters, 105 rear derailer and are both triples. Furthermore, they are both one to two hundred more dollars. Is it better for me to go for the Felt with the better components or get one of the others for comfort. Do the carbon seatstays make that big of a difference over just the carbon post?
