The Stages Power Shimano 105 5800 is the power meter for all riders who are using a Shimano 105 crankset. The Stages Power is pre-assembled on a 105 5800 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.
Riders only need to select colour and length as the Stages Power Shimano 105 fits all styles of 105 cranksets, including compact and standard. 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.
