Our most compact and lightweight module ever designed fits inside the strap. Its soft, rounded contours and flat seams make it an ultra comfortable strap, even out of the water.
Running Dynamics
The HRM-Tri monitor has a built-in accelerometer to measure your bust movements in order to calculate 3 stroke data: 2
The cadence: number of steps taken per minute. It shows the total number of steps taken (left and right feet combined).
Vertical oscillation: the rebound of your movements during a run. It indicates the vertical movement of your torso, in centimetres. HRM-Tri is compatible with several training products and displays your heart rate when paired.
Ground contact time: corresponds to the time spent with your foot on the ground at each step while running (measured in milliseconds).
