I am looking for a 'eighties' 15-20 six-gear freewheel-set for my Merckx bike with campi dérailleur. It is marked *'maillard 700, course, super'*. Where can I find it or an equivalent. My 15-gear is worn but not the 16-20.
Alternatively, is it possible to take the freewheel apart to separate the cogs? If so, do you what is required in terms of tooling, and could I find a single 15 cog? Tnx. Paul.
