The Stages Power meter paired to Shimano’s Dura-Ace 9000 crank is the industry´s only crank-based power meter that is compatible with Shimano´s new FC-9000 crankset. The Stages Power is pre-assembled on a Dura-Ace 9000 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.
New low profile with new door interface – Stages Generation 2
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.
