Stages Shimano XT M8120 Driveside Power Meter

Description

Stages Shimano XT M8120 Driveside Power Meter
If you currently have a Stages Shimano XT M8120 left side crank arm, this Stages Shimano XT M8120 Driveside Power Meter allows you to upgrade to a dual-sided power meter. With power sensors on both the left and right crank arms, you can measure and record total as well as independent left power.
Also, some bike frames cannot fit a left side crank arm-based power meter due to clearance issues with the chainstay. In these situations, this Stages driveside power meter is a perfect solution! It allows you to quickly and easily add power to the right side of your crankset where clearance and compatibility issues don’t exist.
The power meter is extremely lightweight – adding only 15 grams to the weight of the crank arm. All Stages power meters are compatible with both ANT+ and Bluetooth SMART devices, which means you can use your favorite bicycle computer as well as a smartphone or tablet.
The Stages Generation 3 power meter features radio antennas that are 6x more powerful than the previous version. This means better compatibility with both bike computers and watches. The new versions also feature improved accuracy (+/- 1.5%) and have an LED indicator light on the housing for improved ease of use.
