The SRM is to swear most professional cyclists, the performance measurement system. From track cycling to mountain biking, the SRM has made numerous athletes on their way to the top valuable services.

Optimal training requires precise control. An accurate performance profile can be created through the combination of all measurable values such as speed, cadence, heart rate and performance. This profile is the basis for a very specific training, weaknesses and strengths are most exactly shown and can be improved or expanded. Using the information collected can also be driven during the race targeted in the optimum power range, where before the end of the race no burglary is to be feared. So you can with the correct pacing, using the power meter, realize the best possible result for your performance level.

Eight strain gauges measure the introduced torque which is charged together with the instantaneous angular velocity to the entered performance. The measurement takes place without losses with an accuracy of +/- 1%. The measured values are transmitted via ANT + protocol and are all also ANT + devices dominant recyclable. Thus, Garmin Edge devices can be used with the SRM power meter crank.

Your performance is displayed and saved on the Power Control PC8 cycling computer. This is to consistently meet the needs of athletes and waives gimmicks. All relevant values such as power, heart rate, speed, altitude data Training Peaks metrics such as TSS (Training Stress Score), NP (Normalized Power) and IF (Intensity Factor) are displayed. The display is also configurable. To record and analyze the PC8 has a GPS sensor. With a storage capacity of 500 MB up to 4000 hours of training can be recorded. The training sessions are stored as files and Fit can be evaluated with all common training software. To use the PC8 on several wheels, 4 different cycling profiles can be stored.
