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 a 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.
