Stages Power meter for riders looking to add power to their existing FSA or SRAM crank. The Stages Power is pre-assembled on the Stages Power carbon left crankarm.

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 directly compatible (no additional components needed) with 386EVO drive side cranks. It can be retrofitted to SRAM Red 22, Force 22 and Rival 22 BB30 road and SRAM Mountain (168mm Q) BB30, as well as select Truvativ, drive side cranks using three Stages bottom bracket kits (sold separately). This new Stages Power meter will not fit SRAM's GXP bottom bracket 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.
