Selling a Shimano Ultegra FC-R8100 drive-side crank arm and spider. This unit has seen less than 100km of total use and is mechanically perfect. Unfortunately, I had a chain drop on my very first ride which resulted in some cosmetic scratches on the outer face of the crank arm (see photos). Beyond these surface marks, the crank is in pristine condition with zero structural damage and virtually no wear. Model: FC-R8100 Arm Length: 175mm Speed: 12-Speed compatible Condition: Excellent mechanically, Fair/Good cosmetically due to chain rub. Great opportunity for someone looking for top-tier performance who doesn't mind a few scratches, or for a race bike where weight and stiffness matter more than a showroom finish.
