Amateur riders, weekend warriors, seasoned professionals…everybody is affected by fatigue during a ride, and the change in body posture it brings along with it. During a time trial or triathlon bike leg, this results is a less aerodynamic position on the bike and thus a slower ride. But how do you notice this change in body posture? Well, you couldn't up to now. But that has all changed with the arrival of the Lazer Inclination Sensor. WHAT? The Lazer Inclination Sensor is a body posture monitor that allows you to track your aerodynamic cycling posture in real time. The monitor tracks your head and helmet position and provides you with tactile or acoustic feedback when you are out of your optimal aerodynamic position. Before using the monitor it should be calibrated towards your optimal aerodynamic cycling position. For the best result, the calibration should take place in a wind tunnel with the help of aerodynamic experts. But it works just as well when you visit a training center or shop with experienced professionals to help you find that ideal aero position. The monitor aims at making you aware of your head position while riding, and guiding you towards that sweet spot where you cheat the wind as best as possible.
