Shimano FC-R9100-P dual sided power meter

The cranks were removed from my bike before I sold it. My new bike has a power meter installed already so these are for sale. I ran them on my Shimano Ultegar 12 speed Di2 previously. I used the black magnet on my previous frame. this was removed and is included with the sale, but if you wanted to use the black colour again, I would advise to purchase a new one. The white magnet has never been used. There are the normal wear marks on the cranks, but they are good value for a dual sided power meter.
