When Mike adjusted his bicycle, I thought I was watching a chess game. He would stare at a part for a while before he acted. Then we would wait for his opponent's response. For example, he stared for ten minutes before tightening the rear sprockets. Then he rode the bike for a minute, analyzing the change in the bike's performance. At first, I thought he was too careful. Now, I realize he didn't want the bicycle to become his Waterloo.
