This paragraph seems to claim that Nivex manufactured two different versions of their derailleur:

  • The 'Course' which has a capacity of 16 teeth.
  • The 'Grand Sport' which had unlimited capacity.

I am unclear about the difference between the two. Each version is available in either clamp-on or braze-on forms.
