Abstract	The saddle is one of the most complex bicycle components providing both comfort and support while pedalling. Several studies have been carried out on bicycle saddles in recent years including medical ones to identify any correlated pathologies, and others to optimize design and sports performance. There are various types of commercially available saddles but they are all fixed geometry. The main identifiers of these designs are their length, nose inclination and the geometry of the support of the ischial tuberosities and pubic rami (wide, narrow, flat, furrowed etc.). So as the literature suggests, the fixed-geometry saddle on today’s market has only partly resolved the anatomical pathologies related to extended saddle time. Consequently, the aim of this study is to develop, through interactive Re-design methodology, a variable geometry saddle (VGS) prototype for amateur cyclists capable of reducing the onset of saddle pathologies and improving pedalling comfort. The VGS was developed which can be adjusted to the physico-anatomical requirements of the rider as well as to various ride conditions (uphill, flat and downhill). The simple adjusters affect nose inclination and the width of the saddle back. In particular, the nose mechanism allows on-the-fly adjustment. The VGS developed could also allow the cyclist to identify the most congenial subjective geometry to help choose among commercial alternatives. An electroneurograph test on the pudendum nerve was also performed on five male amateur cyclists to see whether there were any effects with a variable saddle geometry compared to a fixed-geometry commercial saddle.
