The Stages Power meter is built to the proprietary Stages Power carbon left crank arm. The full carbon fiber Stages Power meter and crank arm is compatible with many SRAM GXP road cranks.
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.
