Colonel thank you, I do plan to run the tandem as a double and the TA chart for a Tandem might be for a triple at 127 mm ( I noticed that the chart says a double with Shimano is 115 mm and 118.5 mm with # 344 T.A. spindle.
Also the rear Drum brake Hub spacing on this Gitane Tandem is 124 mm with a 5 speed freewheel, does the wider rear hub effect the width of the BB spindle?
