Evaluating the central pressure point to determine the optimal saddle setback
Journal Title: Journal of Science and Cycling - Year 2015, Vol 4, Issue 2
Abstract
Over half of all cyclists describe discomfort at the saddle as limiting condition. (Detori & Norvell, 2006) The saddle setback is an important parameter to consider when aiming to improve the comfort for sportive road bike riders in a professional analysis of the position on the bike. Traditional method Knee Over Pedal Spindle (KOPS) determines the saddle setback using the distance that the patella come over the centre of the pedal spindle This method, however, lacks empirical background and following expert advices gives a range of 80 mm for optimal setback position. (Burke and Pruit, 2003; Gressmann 2006). This paper empirically analyses the effect a change of the saddle position in the sagittal plane (setback) by ±10mm has on the position of the knee joint as well as the pressure parameters central pressure point (COP), maximal pressure and loaded surface on the saddle.
