I've got too many bikes around to ride anything a LOT these days (I'm up to 17 bikes in the house), but I do like them to look nice. I do have a tendency to hold onto the old parts that I take off bikes. My Davidson Tandem supplied a couple sets of mid-80's Specialized cranks I've still got hanging around and I'm quickly piling up parts as I swap and try stuff. I'm pack rat by nature. :|
