Spine Flexibility and Pelvic Rotation are inextricably linked to saddle comfort—How flexible your spine is and by how many degrees your pelvis rotates determines which saddle and components fit you.

High body flexibility and no pelvic rotation whilst pedaling. You need a flat saddle.

    1. Introduction

    Spine Concept EVO is the result of a 3-year long study on the BICYCLE-RIDER INTERFACE, whose primary objective was to gain a better understanding of the biomechanics of bicycling and the effects that saddle and position have on the biomechanics of a cyclist.

    The study has utilized a fitting bike on which the positions of the saddle, handlebars and pedals can be independently manipulated. The bike has been custom instrumented with force transducers at the seat post, stem and bottom bracket. The goal was being able to measure those characteristics that so far have been determined only by feel. The anlysis of the huge amount of data that this study produced was the generator of our new saddle selection concept and of a new range of dedicated products.


    The initial group of experiments was performed to understand how the forces generated when pedalling are distributed on the contact points at:

    Different power outputs
    Different cadence
    Different hands position on the handlebar (Tops vs. Drops vs. Hoods)
    Different handlebar Stack and Reach


    The second group of experiments was performed to learn more about:

    Front-Rear Wheel Rider Weight Distribution (it showed substantial differences between different types of bike fitting methods). Center of Pressure Location (it defines the correct anatomical centre of a saddle).

    The final phase of the study investigated the body/machine interface more in details through: Saddle Discrimination Ability, a triangle test run to find the most reliable subjects that later performed a Subjective Rider Comfort test, which determined the relation between anatomical characteristics and shape, width of their preferred saddle.

    Multiple subjects have been taken their anthropometric/anatomic measurements and rode on a stationary bike with their own bike fitting measurements (either self fitting or commercial bike fitting). The stationary bike was equipped with several strain gauges on every contact point, a power meter and a speed/cadence computer.

    Data were recorded and analysed to determinate any existing correlation between subjective feelings and numerical results. Final report generated the Spine Concept EVO and a new range of products to better answer consumers’ needs.
