Well I've been looking over the site for awhile and thought it was about time I joined. I got back into cycling three years ago and bought a Trek 7200, mainly because it was a jack of all trades kind of bike. I use it mainly for commuting. It is set up with a single speed conversion kit for the winter. I might be upgrading the components in the spring.
I also have a 2Danger (Bicycle Outdoor Co's house brand) Vuelta Comp road bike (with 105s and a Truvativ crank) which saw some commuter duty and a Bianchi Via Nirone (with Campy Veloce components, except the Bianchi house brakes, which I'm replacing).
I used to have this rigid mountain bike I bought in Korea in 1989. Road it on three continents until it finally died. It weighed a ton but took all kinds of abuse.
I'm in the market for a fixed gear. Probably going to get a Bianchi Pista. I'm going to be using it for training and riding around town.
Most of my riding is commuting. I've done some day trips with friends and been up to the Critical Mass in Frankfurt a couple of times.
