          Description
          Stages Power L Shimano Ultegra R8000 Power Meter 172.5Mm. Stages has set the standard for user-friendly, super-accurate, exceptionally durable power meters that also are astoundingly minimalist in structure. Furthermore, this latest, third generation version of the Stages Power Meter sports slightly redesigned electronics, providing improved accuracy, as well as adding an LED indicator light to the housing to show battery life and confirm that the power meter is awake. The Stages Power L Shimano Ultegra R8000 Power Meter features a non-drive side Ultegra R8000 crank arm with a factory-installed power meter that adds a mere 15 grams to the crank arm's weight. You simply remove your existing Ultegra R8000 crank arm, replace it with the Stages arm, and then pair it with your Garmin or other ANT+ or Bluetooth Smart compatible cycling computer. That's it! With no moving parts, and everything protected by a high-strength ABS-PC housing, the Stages power meter preserves the structural integrity of the crank - all while seamlessly adding the ability to measure your power. Furthermore, the Stages power meter also measures cadence as unobtrusively as it measures power using an accelerometer - the same technology used to tell your smart phone how to orient its screen. The proprietary circuitry houses this cadence tool, allowing the meter to eliminate the antiquated need of magnets, external sensors, cables, and zip ties to measure cadence. This modern technology also allows the meter to capture multiple positions per revolution, resulting in a faster response and better overall data. To retain power accuracy, Stages power meters are equipped with ATC (Active Temperature Compensation). Different temperatures cause strain gauges to expand and contract a specific amount. ATC allows the power meter to compensate for temperature changes that would otherwise affect the strain gauges and their ability to accurately measure force. More importantly, Stages ATC auto-adjusts on the fly, without the need to stop pedaling.
