This sale is only for the drive-side crank-arm and chainrings that was taken off my 2016 S-Works Tarmac. I'm selling it because I had not tightened the pedal on the non-drive side crank and the pedal pulled out, damaging the threads. I am including that non-drive-side crank for parts-only in the off chance that the buyer might repair the threads or just throw it away. The drive-side crank-arm and chainrings do have wear and tear on them, as they were on my bike for 5 years before being pulled off. I had taken the bike to my LBS and they were not aware of any possible repair to the non-drive side, so I had to replace the entire unit. It's taken me a long time to get organized enough to post it here on ebay. When I had the original issue, I tried to find a replacement for the non-drive crank but none were available at that moment, otherwise I would have gone that route. I have zero knowledge of cranks and how they are installed in a bike, so the only extra parts that I have are what the bike shop gave me, which are the two rings and the screw as shown in one of the photos. Let me be clear -- the non-drive-side crank arm will be sent, but the threads are damaged, so it is very doubtful that they will be of any use whatever. If you do not see any point in receiving that part, let me know and I will toss it before shipment.
