In another disclosed embodiment, a method of fitting a bicycle saddle to a human rider comprises measuring a sit-bone width of the rider, determining a preferred riding posture of the rider, and assessing a saddle characteristic suitable for the rider based on both the rider's sit-bone width and the rider's preferred riding posture.
