Key Concepts of Retül
Retül tools, technology and methodology are built on three foundations that result in the application of accurate, objective and comprehensive bike fit data to a rider's position on the bike:
Using motion capture technology, Retül records a rider's position while he or she is in motion, therefore creating the most realistic picture of the rider's actual pedal strokes and body positions when out on the road and trails. Riding a bike is different than sitting on a bike, and capturing data dynamically presents a clearer and more accurate picture of a rider's movements.
Fit data collected in a traditional two-dimensional plane (such as video) is fairly limited because the fitter has to isolate a single view at time. In order to see how all of the applicable movements of the body are working together, the frontal and sagittal planes of a rider should be viewed as interdependent reference points. Retül's motion sensors simultaneously gather data on multiple angles of the rider in three dimensions so a fitter can not only see measurements such as knee and hip angles, but also lateral knee tracking and hip lateral travel.
Slight inaccuracies (the difference of millimeters) can drastically change a rider's feel after a ride. The Retül system is accurate to within less than a millimeter, creating true objective data which can be utilized by the fitter for the perfect biomechanical fit. Small adjustments can make a big difference in alleviating back, knee or neck pain, and those adjustments will improve a rider's performance.
