I believe everyone needs to focus on the most important component...the frame!<br /><br />the drive train, wheels, etc, can be replaced/upgraded, but all the dura-ace or record in the world won't help a cheap-ass frame.<br /><br />at the same time, no one should be investing in an 8 speed if they think they might want to do more than ride in the park with the kids.<br /><br />remember, the frame is the central piece of any significant bike purchase.
