A triple with a 12 speed cassette will give you those 36 speeds.

BTW it has been suggested by a few that I hate technology which is not true. FYI before I retired, I worked on almost all office machines from typewriters up to and including laser printers and mainframe computers.

Also Im not trying to say that anyone that enjoys having an electronics suite on his bike and enjoys it should not do so. All that I am saying is people should just go with the joy of cycling, watch their surrounding, and stop and smell the roses. Riding a bike should be carefree and fun. In todays world it is one of the few fun things left.
