Why We Like The Shimano 105 Gen 3 L Power Meter Crank Arm
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.

Change the way you ride
- Familiarity:
- I've used it several times
Excellent product, simple install, and easy to configure with your smartphone. Changed the way I ride almost immediately. If you are looking to get faster and ride longer and have never had a power meter before (like me) this one is the cheapest way to do it. I used to watch my speed to judge my effort in my workouts but watching my power output is a huge eyeopener.
