Gen 2 4iiii Precision Power Meter on a 172.5 Shimano R80000 left hand crank arm.
Great used condition. A few marks and scuffs as per photos.
My 4iiii meters have been super reliable after a poor experience with Stages.
Sale is due to a new bike being fitted with a dual sided meter.
I’ll include a new quality battery.
