This fit suggestion system is the next step from the original spine concept you may have previously been familiar with. You can download the app for Android and iOS systems, which will guide you through the process of finding the right saddle for you.Comfort from your saddle comes from having the right fit by looking at the overall shape of the saddle. The spine concept evo is a two-stage process focused around your spinal flexibility, body weight on the saddle, and power output.1. Spine flexibility and pelvic rotation are inextricably linked to saddle comfort - how flexible your spine is determines which saddle shape fits you. - Arione / Snake - a flat saddle, suits flexible riders who tend to ride with their pelvis in a neutral position and be very active along the length of the saddle. - Antares / Chameleon - a slight curve towards the rear of the saddle, slightly wider than the Arione. Provides some pelvic rotation support while still allowing some movement of the rider on the saddle. - Aliante / Bull - a more significant waved shape in this saddle provides support for the pelvis while in a rotated position. This can happen as a result of reduced spinal flexibility, meaning the rider's pelvis must rotate on the saddle in order to reach forward into the riding position.2. Power and weight through the saddle Once you have found your shape, then the app can help you select the right width for you. It looks at your power output and weight to determine how much weight is being applied to the saddle vs the pedals and will then recommend the correct width for you.
