STAGES CYCLING Power Meter LR Shimano XTR M9100 | M9120 | 32 teeth
With the Stages LR power meter, the manufacturer who made one-sided power measurement acceptable is now launching a power meter with two-sided measurement on the market. However, that does not mean that the manufacturer doubts its concept of measuring power on a crank arm. Rather, the LR power meter is an addition to the range. Measurements on both sides make sense for riders who, due to anatomical peculiarities, have strong power deviations between both legs when pedaling and for riders who want to analyze and optimize their pedaling technique more precisely.
The power measurement sensors are based on those of the established Powermeter L power measurement cranks of the current generation and weigh just 30 grams more compared to the M9100 crank without power measurement. Thanks to a further improved active temperature compensation, the measurement inaccuracies are kept very low at +-1.5%. In addition to the isolated power measurement for each leg, data on the pedaling efficiency can be obtained and evaluated via the two-sided measurement. The cadence is measured via an internal, improved accelerometer, so that no additional magnet is required. In conjunction with an integrated ring laser, the cadence resolution is even more precise. In order to be prepared for bad weather, the Stages LR power meter is waterproof according to the IPX7 standard (temporary submersion). The Stages power meter is compatible with the Stages Dash and all ANT+-capable bike computers and the latest smartphone models via the ANT+ and Bluetooth Smart transmission standards. Firmware upgrades can be carried out quickly and easily thanks to wireless transmission to the power meter. An integrated LED display visualizes the battery status and the calibration result even without a connection to an app or the bike computer.
