Fit from Bike

ROAD Tandem. If you have a bike(s) that fits you well, tandem or singles, look at the drawing below and measure your bike (A and C for the captain;  E for the stoker) and look at the chart below. As with the measurements above, the chart and information below may not work for every type of bike and everyone, however, they should "get you in the right ball park. For new or recent vintage da Vinci bikes, it should be very close to the mark.
