Here are a few pics of my beater...a 1988 Peugeot Fun Star that was bought new in '88 when I lived in Germany. All I have replaced are the tires, brakes and pedals...everything else is original. It's nice taking a bike out when it's really crappy (or in the winter) and not have to clean it or anything (when it's wet, we have some pretty nasty clay/mud around here). The thing just keeps on taking a beating and coming back for more. The only problem is that it handles like crap!
I'll take some new pictures of the Rockhopper with the recently added X517/XTR wheelset in a bit and post them up later.
