SRM PowerMeter 9 – The Next Generation

SRM Spider PowerMeters are the Origin of mobile power measurement. Since 1986 we have continuously refined our PowerMeters to meet ever-higher standards in technology, accuracy, and reliability. For that reason, our PowerMeters are widely seen as the Gold-Standard for training with power.

Our 9th generation is our best PowerMeter yet and takes our proven formula and updates it with modern features. The result is a PowerMeter that is easier to use, even more accurate, even longer-lasting, and has improved connectivity.

Thanks to a combination of angle and torque measurement, the PM9 is now able to measure with higher accuracy in very low cadence situations and oval chain-rings do no longer have an impact on the recorded data. The integrated temperature sensor allows for maximum accuracy in changing conditions. Users are now able to show L&R balance, as well as combined Pedal smoothness. With a total of 8 strain gauges and 16 measurement-grits, SRM PowerMeters offer the best measurement accuracy in the industry!

PowerMeter 9 comes with many usability improvements. First is the Magnet-less cadence mode, which allows you to use the PowerMeter without any cadence magnet.
PowerMeter 9 can be used with ANT+ and Bluetooth LE. It connects to pretty much any head unit and comes with a mobile App. The App gives you access to live torque data, battery status information, firmware updates, and much more.
