The Stages Power meter is mounted to FSA's hollow forged Energy 386 EVO alloy non-drive crank arm. This high quality crank arm is forged from 7075-alloy and finished with a subtle graphic to pair with and match most of FSA's BB386EVO road crank sets. NOTE: The Stages Power FSA 386 EVO model will not fit any FSA cranks with the pinch-bolt style interface.

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.
