The Stages Power XTR is the power meter option for all mountain bike riders that are using a Shimano XTR crankset. The Stages Power XTR is available for Shimano M980 (triple/double) or M985 (double) crank arm. Riders looking to add power to their existing crank will need to select length as well as crank model (M980 or M985) due to a difference in the arms’ offset.
The Stages Power is pre-assembled on a XTR left crankarm. It replaces the existing left crankarm which makes installation pretty simple. Due to the left crankarm interface there is no interference with the drivetrain components. Via ANT+ and Bluetooth Smart technologies the Stages Power is compatible with all ANT+ cycling computers as well as with the latest smartphone models.
