Shimano Dura-Ace 9200 Power Crank Arms Info
The Shimano Dura-Ace 9200 Power Crank Arms let you add dual-sided power measurement to a Dura-Ace 9200 drivetrain without replacing your chainring — just the arms themselves, built to the same tolerances as the rest of the 9200 groupset. Power accuracy is rated to ±1.5%, with left and right readings reported independently so you can track side-to-side balance as well as overall output.
Connectivity covers both ANT+ and Bluetooth, so the arms pair with virtually any head unit, training platform, or smartwatch. Battery life is rated at over 300 hours, and the system is waterproof — two things that matter when you're training through unpredictable conditions. Zero-offset calibration is straightforward and can be done on the fly. Seven crank arm lengths are available, from 160mm through 177.5mm, covering a wide range of rider fit needs.
