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.
Showing and stored PC8 cycling computer Your performance on the Power Control. This is consistently oriented to the needs of athletes and dispensed gimmicks. All relevant values such as power, heart rate, speed, altitude data, the Training Peaks metrics such as TSS (Training Stress Score), NP (Normalized Power) and IF (Intensity Factor) are displayed. The display is also configurable. For recording and evaluating the PC8 has a GPS sensor. With a bearing capacity of 500 MB up to 4000 hours of training can be recorded. The workouts are stored files as fit and can be evaluated with all current training softwares. To use the PC8 on several wheels, 4 different cycling profiles can be stored.
Its sturdy Shimano XT crank arms of the power meter is also suitable for tougher gaits in intended use as Enduro or Dowhnhill. The stable and rigid drive 24 mm steel shaft and a rigid, weight-saving Hollowtech II crank design distinguishes the crank assembly.
NOTE: Contrary to the image of the power meter is shipped without chainrings.
