I have a FOLLIS tandem which sports a JUBILEE front and CRANE GS
rear derailleur with first generation SHIMANO bar end shifters.My
chainring set up is 54/47/32 with a fairly wide 14/32 rear freewheel.My
front derailleur handles those front rings very nicely thank you.I
believe we chose that DER as it looked to have the longest front
cage(also was a used item so was very inexpensive).
