Energy and Endurance
The CycleFit program uses the saddle setback as the starting point that the contribution of maximum force has to be connected with the limits of physical endurance. In a 1965 study, an ergonomics group from the Loughborough College of Physical Education proved that for the maximum force, the distance from the pedal axle to the top of the saddle, has to be in a fixed positioning relation to the inseam measurement.
This was again analyzed and substantiated in 1978 by Faria en Cavanagh. Meanwhile, it was also concluded that for prolonged efforts, of great force, a shorter saddle height is required for maximum force. CycleFit advice is derived by taking into consideration that the average cyclist is practicing endurance.
