Stages Cycling Shimano 105 5800 Power Meter Crank Left Arm (2nd Gen)

Stages Cycling Shimano 105 5800 Power Meter Crank Left Only (2nd Gen)

No longer limited to the pricer cranksets, Stages Cycling's Shimano 105 Power Meter Crank Left Arm Only (2nd Gen) replaces your non-drive crank arm for power data collection and instantaneous readout. Riders looking to add power to their existing crank need only select length, as the Stages Power meter for 105 fits all styles of 105 crankset, including compact and standard.

Stages Cycling's power meters have been lighting up the pro and amateur pelotons for some time now and with this edition you have a Shimano 105 compatible option. Regardless of what piqued your interest in power measurement, you’ll find the Stages Power 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. Especially exciting is the Stages Cycling 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 or iPad device, while also keeping its housing impenetrably sealed to the elements.

Stages Power also broadcasts via Bluetooth Smart. Bluetooth 4.0 devices can communicate with Bluetooth Smart devices as well as legacy Bluetooth versions.

Is my bike compatible with Stages Power Meters?

To help find your current crank model, check the inside of the crank arm for the model and length.

The next step is to check the power meter's compatibility with your frame; if the space between your crank arm and seat stay fits a 10mm allen wrench between 5cm and 12cm from the centre of your bottom bracket, this should be compatible.
