Stages Fsa & Sram Carbon Bb30 Interface Gen2


SKU: N/A Categories: ,


Stages Power built to a proprietary Stages Power Carbon left crankarm.  The full carbon fiber crankarm and Stages Power meter is directly compatible (no additional components needed) with 386EVO drive side 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.
