SRM PM9 vs EFXLink

Our 9th generation Spider PowerMeter takes our proven formula and updates it with modern features. The result is a PowerMeter that is easier to use, even more accurate, better to repair 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 not round chainrings 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. PowerMeter 9 comes with many usability improvements. First of all 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. Features: • Magnet-less cadence • Left / Right Balance • Combined Pedal smoothness • Not round chainrings compatible • Automatic temperature compensation with sensor • Rechargeable via magnetic charger • 100 h battery runtime between charges • Compatible with Head-Units using ANT+™ and Bluetooth® • Zwift™ compatible
