The Stages Power meter is built on to a non-drive Shimano Dura-Ace 9100 crank arm specifically and paired with Shimano's Dura-Ace FC-9100 drive side crank.
The new Stages Power meter is slimmer, and 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.
This Shimano Dura-Ace 9100 Stages Power meter is compatible with all Shimano Hollowtech II road drivetrains. The Stages Power Shimano FC-9100 crankset may be used with the 7900 10-spd drivetrain (including Di2) when paired with the CN-9100 chain. Bottom bracket not included.
