The Trek 520 is still running swell. During the weeks, when I haul my kid around in a kid seat (or sometimes a trailer) I have been using my older mountain bike. However, this weekend I plan on taking the 520 for a nice ride. It is an all black bike and it looks really nice. My cheesy picture does not do the bike justice!
oldmtngoat - the all steel frame really is nice. it just rides so nicely and it's so quiet. My alloy road bike made a lot of creaking and popping noises when the cable housings would move or shift in their bosses.
BigBlueToe - The LHT is a really nice bike too. I originally thought about building up a Surly LHT, but in the end, it was cheaper and faster for me to buy the 520. Early this year I did a major overhaul of my old mountain bike, so I have a lot of the tools to assemble a bike but in the end I just wanted to ride - plus I saved some $$ on components by buying a factory bike. I think I'd be happy with either a 520 or LHT, but I'm glad I got the 520. It's a fun bike.
