There are loads of forums for cyclists -- just add the word "forum" to a Google search with a description of the bike in question and you should get some hits. I just sold my old Peugeot and Motobecane road bikes and picked up a Specialized carbon fiber bike and, a couple of days later, a sweet Klein frame. Now I need to decide which will be the "keeper" of the two!
I love bikes... I ride an old Raleigh Super Record that I've converted to single speed to work every day. Occasionally I'll ride a Belgian "Victoria" city bike, my Specialized mtb, or my Trek touring bike (just to keep them "in tune"). My wife isn't real excited about the amount of garage space the bikes take up, but they are a fun, cheap(ish) hobby.
Now, the leather saddle collection that sits under the coffee table in the living room is another story altogether. What can I say? I'm a sucker for a neglected Brooks seat in need of a little TLC!
