I'm planning to ride the l'Eroica event in Tuscany on September 26th. It is a 200 km 'randonee' over the gravel roads of Tuscany where participants are asked to ride vintage or classic bikes. The organizers give 1980 as the cut off year but many ride much older bikes some going back to the early 1900s. Have any of the list members ridden l'Eroica, or intend doing so this year? If so I'd like to get some idea of the terrain.
      I'm planning to ride a Mariposa that I built in 1971 which is fitted with a Campag Paris-Roubaix derailleur. As P-R riders will know the gear range is limited by the length of the drop-outs. At the moment I have a 15-23 freewheel and a 46T ring which gives me gears of 54" - 82". The drop-outs won't allow me a much wider range. The 54" may be a bit of a struggle, so if anyone has an idea of the course profile I would be pleased to hear from them.
      The Mariposa I intend to ride is the only North American bike I've seen or heard of which is built with the Paris-Roubaix drop-outs. Does anyone know of any others?
      Riders of P-R or Corsa derailleurs will know that it is very important to have the correct pointed tooth freewheel sprockets. As far as I know these haven't been made since the mid 1950s. Does anyone know a source? Mike Barry. Bicycle Specialties, Toronto.
