Ludoal Gran Sport

Ludoal Gran Sport derailleur main image

This is a workable copy of a 1950s Campagnolo Gran Sport. Even the details are pretty correct except for the pulley cage plates - which have strange and function-free extra struts.

This Ludoal Gran Sport is extremely similar to some Gambato Gran Sports - but their are significant differences:

  • On the Ludoal the main Allen bolts at the b-pivot and the p-pivot are very like the Campagnolo design - which is not true of the Gambatos.
  • The Campagnolo has a 43mm pulley cage, this Ludoal has a 44mm pulley cage and the Gambatos has a 45mm pully cage. Why? Who can say.
