The Stages Power meter L is built into the proprietary Stages Power carbon left crank arm. The full carbon fiber Stages Power meter and crank arm is compatible with many SRAM GXP mountain cranks with a 168mm q-factor.
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.
