Pioneer Shimano Dura-Ace 9000 Left Crank Arm Power Meter
Pioneer Shimano Dura-Ace 9000 Left Crank Arm Power Meter Info
The Pioneer Shimano Dura-Ace 9000 Left Crank Arm Power Meter is a direct replacement for your existing Dura-Ace 9000 left arm — same spider, same feel, but with strain gauges, an accelerometer, ANT+ transmitter, and a CR2032 battery built into the inside of the arm. If you already run a 9000 crankset, this is one of the most straightforward ways to add power measurement to your setup without replacing the whole drivetrain.
The unit adds 22g and 8.8mm of depth to the back of the arm compared to a stock left crank — total arm weight comes in at 200g. Pioneer rates accuracy at ±2%. The accelerometer wakes the meter automatically once the crank begins to turn, so there's no manual activation required. The ANT+ signal is compatible with any head unit that reads ANT+ power data. One clearance note worth checking before you buy: if your frame runs an under-bottom-bracket brake cable, Pioneer recommends a minimum of 10mm of clearance on the back of the arm.
