Stages Dura-Ace 9000 G2 Power Meter 172.5

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.
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.
