The recalled model codes are ULTEGRA FC-6800, FC-R8000, DURA-ACE FC-9000, FC-R9100, and FC-R9100 P.
What to do:
Consumers with cranks with production codes that match the recall are being told to visit a bike dealer for inspection. (we can do this), Consumers with cranks with the codes and which show signs of bonding separation or delamination will be given a replacement crank and installation. Shimano expects fewer than 1% of the inspected cranks will require replacement.
At this time, with information we have now, the replacement crank will take 7-14 days and can only be done by specific (larger) dealers, (we are not one of them- this could change, we are in contact with Shimano about this and waiting for their response or solutions)
