Description 
 
Stages Power paired with Shimano’s Dura-Ace 9100 crank. The Stages Power meter is pre-assembled on a Dura-Ace 9100 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. 
 
The new Stages Power meter is slimmer, and up to 28-percent lower profile than our original meter. It's sleeker by way of a 17-percent reduction in frontal area, and we've also made it stronger. The new housing design increases the strength of the battery door and housing connection by 200-percent over the previous design.
