Hi. I am looking into getting a new, and my first road bike. I have been riding a hybrid for the last decade or so. I typically ride 20-40 miles on an average ride. The bikes that have been recommended for me are the Felt ZW75 and ZW6 and the Trek LEXA SLX. Any input or direction. I do understand general differences in the aluminum/carbon fiber combo vs the full carbon fiber. Not sure the direction to take. Thanks for any info!
