In recent years, a cyclist’s biomechanical assessment has evolved into a dynamic form given that the traditional instruments available (measuring tapes, wires, protractor) do not record accurate measurements while the rider is pedaling, and we all know that cycling is a dynamic activity.
Retül is one of the first kinematic analysis systems created exclusively for the assessment of the bicycle position (Road, MTB, Time Trial, Triathlon, Track). The system incorporates an extraordinarily accurate 3D motion capture technology, originally designed for the surgical industry. With the Retül system you get a huge amount of data, acquired in a dynamic and 3D way, tracing all moving body parts simultaneously, while the rider pedals and undergoes different load regimes on his or her bicycle.

The Retül process examines the moving body over three dimensions, unlike an observer who looks at a cyclist while pedaling and cannot measure lateral, vertical, and horizontal movements simultaneously. The result is that the cyclist will have a true adaptation of the bicycle to their movement patterns, maximizing efficiency and avoiding incorrect postures and movements which could lead to long-term injuries, joint problems and more.

The fundamentals of the Retül system are objective, dynamic and accurate data. Each cyclist has his own physique, a unique biomechanical set-up, so there can’t be universal parameters for the evaluation of each individual. Buying a new bicycle is a fun and exciting experience, but riding a bike that’s features are not properly tailored can cause frustration, pain or injury, and can eventually lead the cyclist to hang up their bike.

How does the Retül system work?

Retül is born out of a combination of technical training and specialization and therefore has a many years of experience in scientific research related to the biomechanics of cycling. For this reason, the analysis system is based on the exact requirements of the “technician”: it is an active system that uses infrared LEDs (light emission diodes) applied to cyclist’s body in eight clearly defined anatomic points.

Retül‘s active markers, once placed on the subject, emit a light signal that is captured by the four infrared cameras that only have to identify the marker, therefore not needing calibration by the operator, as in the case of past systems. Thanks to the interaction between hardware and software, the installer can read in real time a set of data that represents the cyclist’s movement pattern, and immediately evaluate the effects of any changes made.
