The SRM is the performance measurement system on swear most cyclists. From track cycling to mountain biking, the SRM numerous athletes has provided valuable services on their way to the top.
An optimal training requires precise control. You can create an accurate performance profile over the combination of all measurable values such as speed, cadence, heart rate and power. This profile is the basis for a very specific training, strengths and weaknesses are most exactly shown and can be improved or expanded. Use the information gathered can be driven selectively in the optimum power range even during a race in which no slump is feared before the end of the race. So you can with the correct pacing, using the power meter, realize the best possible results for your performance level.
Eight strain gauges measure the introduced torque which is charged together with the instantaneous angular velocity to the entered power. The measurement is made without loss 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.

At just 523 grams including chainring well being able to train one of the lightest variants on mountain power controlled. The chainrings with Narrow-Wide tooth profile keep the chain reliably in place.
