Most tandems use 73mm BB shell width. Length / type of spindle will be dictated by the model of cranks you are fitting. Can't be any more accurate without further information.Make mine an Italian, with Campagnolo on the side..0

No more info unfortunately, but thanks for that nugget.The only bad view from the saddle is of the point of impact rising rapidly to meet you.0
