OK guys, I'm not buying a bike with disc brakes. I mentioned the Disc Trucker to be polite. Indexed downtubes are high tech to me, let alone bar-ends. I'm happy with good o'l canti's; my lame single-pivot calipers have gotten me through three winters of commuting without incident.
And back on subject, I do think I'll be stopping by the LBS on Tuesday to put a payment down on the new 520. I've never owned a new bike before
Thanks for the input and help guys, I really do appreciate it!
