Garmin HRM-600, Pirelli P-Zero SLR, and Pirelli P-Zero Race SLR Tyres Tested for 200 Miles

The Garmin HRM-600 was tested alongside the Polar Street X. The HRM-600 offered accurate heart rate monitoring with a small discrepancy of 2 beats per minute compared to known gear. Battery life was around 14 hours, which is comparable to the Pirelli P-Zero SLR tyres. Comfort was rated as solid, but not perfect.
