STAGES CYCLING Power Meter L Shimano GRX RX810
The Power Meter Stages L RX 810 is the first Gravel Bike specific power meter in the Stages range and was developed for the Shimano GRX group. The power meter is preassembled on a left Shimano FC-RX810 crank arm and, once the correct crank length has been selected, can be replaced extremely quickly and easily with the left crank arm of the existing crankset. A great advantage over other systems: there is no intervention in the tuning of the wheel and the gearshift.
In the L- (Left-) power meter all features from the current LR- (Left-Right) power meter have been integrated with power measurement on both sides. Not only the software, but also the hardware has been revised. The measuring accuracy could be 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. With 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. To be prepared for bad weather, the Stages LR power meter is waterproof according to IPX7 standard (temporary immersion).
