It is 30 years since arguably the greatest Tour de France of all time, decided in the final time trial by just eight seconds. In the first of our two-part Kilometre 0 about the 1989 Tour, Lionel Birnie and François Thomazeau recall the see-saw nature of the battle between Laurent Fignon and Greg LeMond. Kilometre 0 is supported by Hansgrohe showers and taps.
