Stages L G3 Carbon BB30 Power Meter


Stages Power for riders looking to add power to their existing Sram or Race Face crank. The power meter is pre-assembled on the Stages Power Carbon left crankarm.

Stages Power built to a proprietary Stages Power Carbon left crankarm. The full carbon fiber crankarm and Stages Power meter is compatible with Sram Red 22, Force 22 and Rival 22 BB30 road, Sram Mountain (168mm Q) BB30, as well as selected Truvativ, drive side cranks or Race Face Next SL cranks using one of five Stages Spindles. This Stages Power meter will not fit SRAM's GXP bottom bracket interface. (See powermeters for Stages Carbon for SRAM MTB GXP and Stages Carbon for SRAM Road GXP)

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.
