he Stages Power Meter L for the current Shimano XTR M9100 | M9120 cranks . The power meter is preassembled on a left Shimano XTR M9100 crank arm and, once the correct crank length has been selected, can be exchanged extremely quickly and easily for the left crank arm of the existing crankset. A great advantage over other systems: there is no intervention in the coordination of the wheel and the gearshift.
In the L- (Left-) power meter all features from the current LR- (Left-Right) power meter with bilateral power measurement have been integrated. Not only the software, but also the hardware has been revised. The measuring accuracy was increased to + -1.5%. The antenna has also become stronger and sends the data at 6 times higher intensity, which reduces the risk of dropouts. The L-Powermeter are also compatible with even more bike computers. The integrated cadence sensor was also upgraded to measure even more precise values. Optionally, the cadence can now also be measured using a magnet. As a positive side effect, the new hardware ensures a weight reduction of 5 grams compared to the previous version.
Active temperature compensation ensures that the Stages power meter is measured accurately, even with large temperature fluctuations. Via the ANT + and Bluetooth Smart transmission standards, the Stages power meter is compatible with all ANT + -compatible bike computers and the latest smartphone models. Firmware upgrades can be carried out quickly and easily thanks to the wireless transmission to the power meter. An integrated LED display visualizes the battery level and the calibration result even without a connection to an app or the bike computer. In order to be prepared for bad weather, the Stages LR power meter is waterproof according to the IPX7 standard (temporary immersion).
