Product Description
Shimano Dura-Ace R9100 L Gen 3 Power Meter Crank Arm by Stages Cycling
The Dura-Ace 9100 group looks really nice on your bike and even more importantly, works really well. 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 part with the excellent crankset, and you don't want it to cost a fortune. Thanks to Stages Cycling and its Shimano Dura-Ace R9100 L Gen 3 Power Meter Crank Arm, you can simply add on a non-driveside crankarm letting you keep the sleek 9100 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 non-power Dura-Ace 9100 arm you currently have, just make sure you order the right length, 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. The meter also incorporates Stage's Active Temperature Compensation (ATC), which compensates for the natural expansion and contraction of the strain gauges by adjusting the readings depending on external temperature. ATC accounts for those temperature changes without requiring you to stop pedaling in order to zero the system. Overall, the power meter adds less than 15g to the crank, which is a tiny tradeoff for its ability to capture power information as it transfers from the pedals into the drivetrain. A simple coin-cell battery and wireless firmware downloads make this power meter easy to service and keep up to date.

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
