In the world of cycling, performance metrics are everything. Whether you’re a professional cyclist or an enthusiastic amateur, understanding your performance data can make a significant difference in your training and race outcomes. That’s where power meters come into play, and SRM has been at the forefront of this technology since 1986. Their latest offering, the SRM PowerMeter 9 (PM9), promises to set a new standard in the industry. Let’s dive into the details.
The All-New Chassis Design
The PM9 features an all-new chassis design that is more robust than ever. This design ensures efficient and consistent force transfer, which translates to ultimate accuracy in your readings. The improved sealing also increases water resistance, making it a reliable companion in all weather conditions.
Compatibility with eeWings Mountain Cranks
The SRM PowerMeter 9 is designed to be used with eeWings mountain cranks from Cane Creek. These titanium cranks are not only lightweight but also incredibly durable and stiff. They are specifically designed for aggressive trail and enduro mountain biking, offering 20-30% more stiffness than carbon cranks. With a 10-year warranty, these cranks are built to last.
Battery Life and Charging
One of the standout features of the PM9 is its impressive 100-hour battery life. Charging is also a breeze, thanks to the fully sealed magnetic connector. LED lights on the device indicate cadence, charging status, and when it’s fully charged.
The PM9 offers an accuracy of +/- 1%, ensuring that you get the most reliable data possible. The spider weight is just 103g, and it features a BCD 4 bolt 104. Thanks to a combination of angle and torque measurement, the PM9 can measure with higher accuracy in very low cadence situations. The integrated temperature sensor also allows for maximum accuracy in changing conditions.
The PM9 comes with many usability improvements, including a magnet-less cadence mode. This feature allows you to use the PowerMeter without any cadence magnet, making it even more user-friendly. The device can be used with both ANT+ and Bluetooth LE, ensuring compatibility with almost any head unit. The accompanying mobile app gives you access to live torque data, battery status information, firmware updates, and much more.
The Gold Standard in Power Measurement
SRM Spider PowerMeters have long been considered the gold standard in mobile power measurement. The 9th generation takes this legacy forward with modern features, making it easier to use, more accurate, longer-lasting, and with improved connectivity.
