Ok I'm a potentially new road rider looking for a good recreation and commuter road bike. I have $650 to spend on a 24spd bike and am looking for the best deal for the price. After much shopping I've come to the conclusion that various bike co.s pick and choose the value of components. Almost all bikes provide an 6061 aluminum frame and Shimano sora gearing; however some have carbon forks or alum. forks, sealed or unsealed wheels, hell the $800 Novaro Divano doesn't even come with sealed wheels. Besides the position comfort and durability, what components should I look for in a road bike that are worthy of the $650 price tag? Here are some links to bikes I checked out below.
