The Stages Power FSA Energy MegoExo is the power meter option for all riders who are looking to add power to their bike and are using a FSA MegaExo 24mm crankset.
Stages Power meter is pre-assembled on an Energy 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.
