This is for my recent Paramount find, please help if possible....

My question refers to the compatibility in chain length, cage length, and crankset. As some of you already know, it's a Campy triple. The freewheel I plan to use is is a Shimano 600 13/23. The RD I plan to use is a Nuovo Record. Does anyone see a problem with this setup? Should I still need a long cage RD with the smaller freewheel? There really are no hills around here that the small front and 23 couldn't handle. The final 13/large combo would be close to average, so top speed would still be there. On an average ride I find myself on the middle of a triple, and middle to smaller of the rear cogs. I'm just thinking out loud. It's still in the planning stage so none of this is set in stone.,,,,BD
