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.
