The vertical distance from the center of the
bottom bracket to the top of the top tube will be calculated based on the
dimensions you provided on the Bike Setup form. You will need only to supply the
seat tube offset in the space provided and then select Calculate Seat Tube
Angle, then select Return to Bike Setup.
The seat tube offset is the horizontal
distance from the center of the bottom bracket to the center of the seat tube at
the center of the top tube.
Note: If the bike has a sloping top tube, it
may be necessary to re-measure the bottom bracket to top tube distance as the
top tube height on the setup form is measured at the front of the top tube.
