This is my Peugeot. It is a 1985 model, a believe a it is a PY model. It has a steel frame, but basically everything else on it is aluminum. Despite it's vintage, it's gotten to be a pretty sweet ride since I restored it, although the rear cluster has a few kinks in it (I need a new wheel). This is a picture of it before I finished fixing it up. It doesn't look much different now.
This is my Specialized "Ground Control." As you can see, it is a mountain bike. I think it's from around 1996. It's an early full suspension. It's held up pretty well over the years. The first owner road the hell out of it, my dad said, as do I. The components are all Shimano XT (w/ the exceptions of the LX front derailleur and the XTR rear hub). It's a very sweet ride, and it's great for cross country.
