Hello there! I am a new member of this board and have a few questions that I thought the experts on here may be able to help with. I have recently purchased my first bike since I was a kid, and it is a used Specialized Rockhopper that I got at a great price and have put Specialized Fatboy slicks on it. I absolutely love it considering I have $150 in it altogether. I have been researching some better bikes for my needs as I am riding about 12-14 miles a day on my rockhopper and it is all on a paved bike path. I have found the two bikes I mention in the title to fit my needs (basically wanting a flat bar road bike because of riding position, carbon frame and fork, etc.) My question is, can anyone tell me which of the two offer the better quality components? I have come to my conclusion that what I am looking for is a full carbon bike for the weight/speed advantages as well as the vibration dampening ability. Am I correct that this will be the best type of bike for me? How much lighter will these bikes be than say, their aluminum framed lower priced models and how much of a difference will the carbon frame make vs. aluminum? Also keep in mind that I am currently riding a chromoly frame and fork, and the bike seems pretty light to me. Any suggestions are certainly welcomed along with other bikes that fit the bill. Thanks again for your help, and enjoy your riding!!
