The Stages Power meter is mounted to FSA’s hollow forged Energy alloy non-drive crank arm.  

The Energy MegaEXO model fits a variety of FSA MegaEXO road cranksets including alloy MegaEXO cranks 2014 and newer and carbon MegaEXO cranks 2008 and newer (SL-K Light, K-Force Light, etc).

It is not compatible with triple cranksets or the FSA Omega MegaEXO (which uses a smaller spindle diameter).

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.
