Stages Cycling Sram X9 GXP Power Meter Crank - Left Arm Only

Stages Sram X9 GXP Power Meter Crank - Left Arm Only

For SRAM mountain riders Stages offer a power meter as replacement non-drive crank arm for existing SRAM GXP model cranks. Riders looking to add power to their existing crank will need to select length to retrofit a Stages Power left arm to their X9 system.

Technology

You'll find the Stages meter to be the lightest, smallest, most technologically advanced unit available today. The 20g unit houses an array of high technologies adapted from the rapid advancement of modern electronics.

The accelerometer based cadence measurement is possible due to the technology's development for use in smart phones. We’re especially excited about the Stages Power meter’s bilingual communication between both ANT and Bluetooth Smart protocols; the latter gives Stage the ability to ‘future proof’ this power meter with the ability to update its firmware over the air using an iPhone 4S or iPad 3 (or later) devices, while also keeping its housing impenetrably sealed to the elements.
