Why it was recalled
The recalled bonded crank parts can separate and break, posing a crash hazard to consumers.
What to do
Consumers should immediately stop using the cranksets manufactured before July 1, 2019, and contact an authorized Shimano dealer to schedule a free crankset inspection. Only consumers whose cranksets show signs of bonding separation or delamination during the inspection will be provided a free replacement crankset and installation.
