Hi, I was wondering if anyone could tell me more about my bike. I recently got this Columbia Dream Machine last week for $5. I since have put new wheels on it, tires and a seat and bar tape. All I know is that the bike is from the 70s but I don't really know to much about it. Does anyone else have a Columbia road bike? I heard that Columbia bikes NOW are Junk but back in the day they were pretty decent. Yea this bike is heavy but it's pretty fun to ride.
