I'm selling my 2nd generation Stages left crank arm PM, Ultegra 6700, 175 mm. $150 plus shipping.

It's been very reliable. I'm selling it because I picked up a P2M NGeco for the tri bike and I have a PowerTap GS Hub on the road bike, so no need for a third power meter.

I've done several rides with the Stages on the road bike so I could compare it to the GS Hub and they've had the exact same normalized power on nearly every ride, the largest difference was one 4hr ride where the Stages was 2.1% higher (as you'd expect w/drivetrain loss).

I can send pics if you're interested. I can also throw in an Ultegra 6800 right side crank arm (4 bolt style), it just doesn't have chain rings because I moved those on to the P2M. Still asking $150 regardless of whether you want both the left and right crank arms, but shipping will likely go up because the box will be bigger.

Edit: added pictures
