Stages Cycling Carbon Single Leg Power Meter Crank Arm for SRAM Red BB30

You love your SRAM Red 22 drivetrain and its lightweight efficiency, but its one downfall is its inability to measure power and upgrading to a dual leg, integrated power meter crankset just isn't in the budget. Which is why we're stoked to have options like the BB30 Stages Carbon Single Leg Power Meter Crank Arm for SRAM Red. It packs a heap of training utility into a price point that won't crush an annual cycling equipment budget. Because it's made by Stages, this isn't exactly the same left crank arm as your current SRAM Red arm, but the only immediately apparent differences are the Stages branding and the small power meter pod affixed to the arm's inner surface, which adds the ability to gather pinpoint power data to better measure your ride. It utilizes a blend of strain gauges and an accelerometer to chart position and force data 64 times per second and deliver power readings with a claimed 2% accuracy that's right in line with what we'd expect from any quality power meter. The weight conscious riders among us will also appreciate that the Stages power meter adds a paltry 20 grams to the crank arm, which is a tiny sacrifice to gain the data tracking and training specificity having a power meter affords.
