Stages Power Carbon BB30/386EVO 170mm

The GEN 2 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.

GEN 2 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.
