Season 18 of the show features an episode called Breaking the Chain and revolves around a bicycle race. We watched it last night on DVDs rented from our library. Rival teams and rivalries among riders on the same team with brothers, sons of the team owner dad, the main focus of the investigation. Toss in a romantic triangle or two and friction with the locals and it made for a satisfactory whodunnit. Bike nerds will be intrigued by the background activity, with machines being wheeled about and tended to, with only an occasional flub. What is a bike with cantilever brakes doing in the repair stand of a road racing team? Is anyone really racing that bike with straight bars?
