With the PC8 SRM offers a device that is focused entirely on the needs of athletes, and foregoes gimmicks. In addition to common values such as power, heart rate, speed, etc. – the Training Peaks metrics such TSS® (Training Stress Score®), NP® (Normalized Power®) and IF® (Intensity Factor®) are calculated, and the values are displayed. Also, location and content of the various data fields on the display is configurable.
Of course, the PC8 also has GPS (for recording) and is controlled by a light sensor backlight. The light as well as the GPS can be turned off in order to prolong battery life, which is between 10 and 45 hours.
The memory capacity is 500 MB, which can store data up to 4,000 hours of training. A built-in motion sensor turns the PC8 on automatically when riding.
Since many riders have several bikes with power meters, the PC8 supports up to four different bicycle profiles. Selecting the profile for the respective bike prior to departure eliminates the previously required pairing with the power meter.
The SRM PC8 displays up to 7 training zones based on your previously recorded heart rate or power data and automatically calculates your FTP.
