Stages Gen3 L Power Meter, Shimano 105 (R7000), 170mm Crank, Black
Now that you're looking to take your riding to the next level, you want to add a power meter to your setup to maximize your training but you have a couple of reservations. You don't want to waste your existing crankset, and you don’t want it to cost a fortune. Thanks to Stages Cycling and its Shimano 105 L Gen 3 Power Meter Crank Arm, you can simply add on a non-driveside crankarm letting you maintain the aesthetic and precision shifting rings while adding accurate power measurement to your steed.
This non-drive side crank arm is exactly the same as the standard 105 crank arm you currently have with a Stages power meter affixed to its inner surface. Tucked inside this little pod, strain gauges and an updated Gen 3 accelerometer measure torsional force and rotation speed to calculate power and deliver this data to your head unit via updated Bluetooth LE or ANT+ radios with a 6-time improvement in transmission strength. These measurements come with a claimed accuracy of +/- 1.5%, which is very much in-line with the best power meters on the market.
PowerMeter has light scuff due to heel strike. It is only cosmetic and does not affect the operation of the PowerMeter. "Shown in the 1st picture"
