A method and a device are provided for individually adapting the saddle of a two-wheeled vehicle, especially bicycle saddles. The local pressing pressure of the buttocks of a test subject is measured on a adapting device (1) with a measuring saddle (2) and a pressure-measuring device (4) arranged on or in the seat surface at individual points or over a large area and in a localizing manner and evaluated. The two-wheeled vehicle saddle (8) is specifically adapted to the shape of the individual buttocks corresponding to the measuring results and is additionally cushioned where the contact pressure is higher.
