AFAIK the numbers on the back of this and other derailleurs don't mean what a lot of people think. I believe the '36' indicates the maximum "wrap" capacity of the derailleur. It is something like the max of this equation (chainring max + freewheel max) - (chainring min + freewheel min). No way this derailleur can handle a 36 tooth freewheel cog.
