Points that mark the reading zone with millimeter precision!

The Retül system measures the cyclist’s movements in real time using 3D motion capture technology that is tracked by a wireless Trigonometric LED cable connected directly to the cyclist.

How is the cable connected, you ask?
With those little black dots! They are called Retül pre-adhesive dots. These are placed at 8 strategic points on the cyclist by the Biomechanical Assessor or Bike Fitter.
